Esper Hand 2 for Active Users: Work, Travel, Exercise and Daily Life

Quick answer

Esper Hand 2 is a multi-articulating myoelectric prosthetic hand designed for work, travel, household tasks and active daily routines. It combines six independently driven motors, proportional EMG control, configurable grips, IPX5 water resistance, modular servicing and a maximum static carry load of up to 35 kg (77 lb), depending on hand size.

Esper Hand 2 can support activities such as typing, smartphone use, carrying bags, holding cups, driving and moderate exercise when clinically appropriate. It is not intended for swimming, powerlifting, rock climbing, skiing, mountain biking or other high-impact activities. Final suitability depends on the complete prosthetic system, socket fit, EMG signals, training and the user’s individual goals.

There is no single definition of an “active prosthetic user.” For one person, active use may mean working eight hours at a computer. For another, it may include teaching, running a business, travelling, driving, exercising or moving between several of these activities in the same day.

The best prosthetic hand for an active user is therefore not necessarily the hand with the longest specification sheet. It is the prosthetic system that best supports the activities that person actually needs to perform.

Esper Hand 2 for active use: key specifications

These specifications describe the hand itself. The functional limits of the complete prosthesis may also depend on the socket, wrist, connectors, residual-limb anatomy and other components.

What makes a prosthetic hand suitable for an active user?

An active user may need one prosthetic system to support computer work, household tasks, transport, travel, social activities and moderate exercise. The most relevant factors usually include control reliability, socket comfort, weight, grip versatility, battery life, water resistance, expected loads and access to repairs.

The prosthetic hand is only one part of that system. Socket design, electrode positioning, EMG signal quality, wrist components, training and rehabilitation all affect how the hand performs in real life.

Instead of asking only which prosthetic hand offers the largest number of features, a more useful question is: which complete prosthetic system best supports this person’s repeated daily activities?

Esper users have applied their prostheses in a wide range of occupations and routines, including software quality assurance, hospitality, healthcare, teaching, electronics work, driving and sport. These cases illustrate possible applications, but they should not be interpreted as guaranteed outcomes for every user.

What daily activities can Esper Hand 2 support?

Esper Hand 2 is designed to support common daily activities including holding a phone, typing, eating with utensils, carrying bags, holding cups, opening doors and completing household tasks. Configurable grips allow clinicians and users to prioritize movements that occur most often in an individual routine.

Everyday objects require different types of interaction. Holding a phone is not the same as carrying a shopping bag, while a coffee cup requires a different grip from a keyboard, utensil or door handle.

Jelena, a member of the Esper community who was born without her left hand, has documented using Esper Hand 2 for driving, typing, holding cups and applying makeup. Her experience illustrates how grip versatility can support several parts of one person’s routine, but it does not predict identical results for every user.

Successful use also depends on the full prosthetic configuration. A grip available in the hand does not automatically make every object or task equally manageable. Object size, shape and surface, as well as socket stability, control settings and user experience, all influence the result.

What makes Esper Hand 2 suitable for physical work?

Esper Hand 2 combines individually powered fingers, customizable grips, defined carrying limits, and a modular design to support everyday work tasks. These features support activities such as carrying bags or containers, holding cylindrical objects, and handling small components.

Customizable grips for different tasks. Esper Hand 2 includes eight standard grips and supports up to 24 custom grips through the Esper+ app, with up to six active grips in the Basic Kit. Precision Pinch and Tripod provide options for handling small objects, while Bottle and Lateral offer different ways to grasp cylindrical and thin objects. Users can adjust grip configurations for the objects they handle most often.

Power Grip for additional squeezing force. Power Grip increases motor-current limits to produce a stronger grasp. In Esper’s internal Bottle grip testing, force increased from 42 N to 57 N for Small and from 67 N to 112 N for Large—improvements of approximately 36% and 67%, respectively. These results reflect squeezing force under the tested conditions, not carrying capacity. Power Grip increases battery consumption and may shorten operating time between charges.

Weight options start at 425 g. Esper Hand 2 Small weighs 425 g with SWC or 460 g with QDW. Large weighs 576 g with SWC or 611 g with QDW. These figures include the hand and specified wrist connector. For users concerned about prosthesis weight during repeated movements, the Small SWC configuration offers the lowest published weight within the Esper Hand 2 range. The socket, battery, and other components contribute additional weight to the complete prosthesis.

Defined limits for carrying tasks. Maximum dynamic functional carry loads are 20 kg for Small and 25 kg for Large; maximum static carry loads are 30 kg and 35 kg, respectively. These limits help explain the hand’s capabilities more accurately than a single “strength” figure. Suitability for a particular task also depends on load direction, grip, repetition, and the complete prosthetic setup.

Durability and serviceability. Esper Hand 2 uses aluminum fingers and improved finger pads for daily use. Its modular construction allows Esper’s partners and support channels to supply replacement parts. These features matter when evaluating a hand for repeated work tasks and ongoing maintenance, but they do not establish that it is the most durable hand in a comparative test.

Esper Hand 2 supports work within its intended use and specified limits. Carry-load ratings and enhanced grip force do not establish suitability for high-impact activities, powerlifting, or every tool-based operation.

How Power Grip fits into work tasks

Power Grip is an optional app setting for Esper Hand that increases motor-current limits to produce additional squeezing force. For work tasks, it matters because it lets you apply a stronger grasp to an object. The benefit depends on the object’s shape, surface, and resistance to pressure, as well as the user’s ability to control and release it.

In Esper’s internal Bottle grip testing, the Small hand increased from 42 N to 57 N, a 35.7% improvement. The Large hand increased from 67 N to 112 N, a 67.2% improvement. These percentages compare baseline and Power Grip settings within the same test.

Standard grip force and Power Grip test results

Standard figures are Esper Hand 2 specifications. Power Grip figures come from internal tests on EH1 devices; the report states that EH1 and EH2 use the same motors. Engineering must confirm their applicability as Esper Hand 2 specifications. A dash means the source does not provide a corresponding measurement.

The standard and Power Grip columns are not a controlled before-and-after comparison. Their measurement baselines differ, and Bottle results should not be treated as interchangeable with Power / Fist specifications.

What stronger grip means for physical work

Grip force, measured in newtons, describes how firmly the hand squeezes an object. Carrying capacity describes the load it can support under specified conditions. Power Grip does not increase Esper Hand 2’s published carrying limits: maximum dynamic functional carry loads remain 20 kg for Small and 25 kg for Large, while maximum static carry loads remain 30 kg and 35 kg, respectively.

For a particular task, additional squeezing force helps only if it improves object handling while preserving controlled release. More force is not automatically beneficial for fragile objects, precision tasks, or objects that can slip despite a tighter grasp.

Power Grip also increases battery consumption and may reduce operating time between charges. Assess its practical value across the intended task, including grip stability, release, repetition, and battery use. The setting does not establish suitability for heavier work, high-impact activities, or operations outside the hand’s intended use.

Is Esper Hand 2 suitable for work and computer use?

Esper Hand 2 can support office, technical, hospitality, healthcare and other work involving repeated interaction with computers, smartphones, cups, tools or small objects. Appropriate grips and control settings depend on the user’s occupation, socket fit, EMG signal quality and training.

Documented Esper users include a software QA engineer, café owner, automotive quality engineer, rehabilitation specialist and electronics technician. These cases demonstrate possible applications rather than guaranteed occupational outcomes.

For computer work, relevant tasks may include typing, using shortcuts, handling a phone, moving documents and interacting with objects around a desk. Grip configuration can help prioritize the movements used most frequently rather than requiring the user to cycle through unnecessary options.

Work applications extend beyond computers. Fedir has used his prosthesis while preparing drinks and running his café. Olena Pozniakova works in software quality assurance. Alexis Cholas has handled medical materials while working in rehabilitation, and Mykola has used Esper Hand while working with electronics and small components.

In its profile of Esper Bionics, The Kyiv Independent documented Olena’s use of Esper Hand and her experience adapting to the prosthesis after living without one for many years.

The suitability of a prosthetic hand for a particular profession should still be evaluated task by task. Specialized equipment may be safer for work involving extreme loads, impacts, vibration, hazardous materials or environmental exposure.

Does Esper Hand 2 support dexterity and fine motor tasks?

Esper Hand 2 uses six independently driven motors, proportional EMG control and individual finger movement to support both larger everyday grips and more controlled interactions with smaller objects.

Documented Esper users have used the hand for typing, smartphone interaction, applying makeup, handling medical materials and working with electronics. The Associated Press documented Esper user Alexis Cholas performing healthcare tasks and handling small or delicate objects with his prosthesis.

However, real-world dexterity depends on more than the terminal device. Socket stability, electrode placement, EMG signal quality, grip configuration, object shape and user training all affect task performance.

Esper has not published standardized Esper Hand 2 results from assessments such as the Box and Block Test or Southampton Hand Assessment Procedure. The examples in this article should therefore be interpreted as documented individual use cases rather than clinical dexterity benchmarks.

How much weight can Esper Hand 2 carry?

Maximum carry loads depend on the hand size and whether the load is static or dynamic.

A static carry load describes a load held without substantial movement. A dynamic carry load accounts for movement and the additional forces created while lifting, lowering or carrying an object.

These figures are specified limits of the hand itself. They are not recommended everyday working loads for every user and should not be treated as performance targets.

The practical limit of the complete prosthesis may be lower because socket design, wrist components, connectors, residual-limb anatomy, load direction and load duration also matter. Expected loads should therefore be reviewed with the prosthetist at the complete-system level.

An extreme example was documented by The Kyiv Independent. Esper user Borys Bass described damaging components of an earlier-generation hand during military training after supporting substantial body weight through the prosthesis.

“If you try to shoot a machine gun with it, it’s too much load,” Bass explained.

This was an extreme use case rather than normal everyday loading. Feedback from demanding real-world use contributed to Esper adopting aluminium fingers as standard in Esper Hand 2. The example also shows why a rated load should not be treated as a target: load direction, duration and the complete prosthetic configuration matter.

How long do users wear Esper Hand?

Daily wear time varies substantially between users. It can be affected by socket comfort, the condition of the residual limb, temperature, activity level, access to charging, training and the practical value of the prosthesis for the person’s routine.

A long battery specification does not automatically mean that every user will wear the hand continuously throughout the day. Conversely, removing a prosthesis for a particular activity does not necessarily indicate rejection or poor performance.

Wear time should therefore be interpreted as an individual outcome rather than a universal measure of device quality. Comfort and functionality across repeated real-life tasks are usually more informative than a single average number.

Can Esper Hand 2 be used for driving and travel?

Esper Hand 2 can be used during travel, subject to the requirements of the complete prosthetic system. Battery capacity, IPX5 water resistance and modular servicing may be particularly relevant when a user is away from home or a prosthetic clinic.

Users should still plan for charging, environmental exposure, transport conditions and access to service. The hand should be protected from impacts and conditions outside its specified environmental limits.

Driving may be possible for some users, but individual ability, vehicle adaptations and local legal requirements vary. A prosthetic hand should not be presented as automatically making a person fit to drive.

Oleksandr, an Esper user, veteran, QA Lead and father, gradually returned to driving after losing an arm and a leg. He later participated in a rally in Spain as a co-driver, following the odometer, checking route points and guiding the driver with a road book.

His experience illustrates a possible return to mobility and demanding activities. It does not establish that Esper Hand 2 is suitable for every driving or motorsport situation.

Before driving, users should discuss control, comfort and any required vehicle adaptations with their clinical team and consult the applicable local requirements.

How is Esper Hand repaired and serviced?

Esper Hand uses a modular architecture designed to allow individual components to be serviced or replaced without automatically replacing the complete hand. In appropriate cases, serviceable modules may also be handled locally by trained clinicians.

The Associated Press has reported that Esper’s manufacturing and service capabilities in Ukraine allow Ukrainian users to access repairs or resizing without travelling abroad. Esper also operates a service department in Kyiv.

For an active user, relevant service questions include:

• Where can the device be inspected or repaired?

• Which components can be replaced separately?

• Does the complete hand need to be shipped?

• How long is the expected service process?

• What support is available while the device is being repaired?

• Can a trained local prosthetist complete any part of the service?

Maximum load ratings alone cannot describe real-world reliability. More informative measures would include repairs per device-year, repair types, causes and typical turnaround time. Until standardized data are available, service figures should not be interpreted automatically as failure rates.

Is Esper Hand 2 waterproof or water-resistant?

Esper Hand 2 is water-resistant, not waterproof. It has an IPX5 rating without a protective glove and is designed for everyday exposure such as rain, handwashing and dishwashing.

IPX5 does not support swimming, full submersion, high-pressure water, salt water or chlorinated water. After exposure, the hand should be wiped dry and allowed to air-dry at room temperature.

The IPX5 rating applies to the hand itself. It does not automatically establish the protection level of the socket, wrist, connectors or complete prosthetic system. Users should confirm the environmental limits of their full configuration with their prosthetist.

Water resistance can reduce the need to remove or protect the hand during ordinary daily exposure, but it should not be confused with unrestricted use in water.

Can Esper Hand 2 be used for exercise and sports?

Esper Hand 2 may support moderate exercise when the activity, expected load and complete prosthetic configuration have been reviewed by the user’s clinical team. It is not intended for swimming, powerlifting, rock climbing, skiing, mountain biking or other high-impact and extreme activities.

A multi-articulating bionic hand is not necessarily the optimal device for every sport.

Kyrylo, a young swimmer and Esper user, received three different prosthetic solutions: a bionic hand, a mechanical prosthesis and a swimming-specific prosthesis. He uses Esper Hand for daily activities, but not as his swimming hand.

For highly active users, the most functional solution may therefore include more than one terminal device. Esper Hand 2 may support work, travel, digital devices and everyday activities, while a specialized prosthesis may be more appropriate for swimming, heavy training or another task involving unusual loads or environmental exposure.

Using a specialized terminal device does not make a bionic hand a worse solution. It means that prosthetic care is being designed around the person’s actual activities instead of expecting one device to perform every possible task.

Why choosing an active prosthetic hand involves more than specifications

Research on active upper-limb prostheses describes prosthetic use as a human-centered system involving the device, user control, feedback, training and activities of daily living. This supports evaluating a prosthetic hand as part of the complete fitting and rehabilitation process rather than judging it only by grip count or maximum load.

A published review of active upper-limb prostheses also highlights the interaction between device design, control systems and user needs.

The review does not evaluate Esper Hand 2 specifically. Esper-related claims in this article are based separately on technical specifications, company-reported information, independent media reporting and documented individual user cases.

This distinction matters. A technical specification can describe what the hand is designed to do, while a user story shows how one person applied it in a particular situation. Neither automatically constitutes a standardized clinical outcome.

What Esper has learned from active users in Ukraine

Esper’s work in Ukraine has provided direct feedback from people returning to healthcare, hospitality, software, engineering, driving, technical work and military service after limb loss.

These experiences have informed product development and demonstrated how different prosthetic requirements can be. A QA engineer, café owner, swimmer, rehabilitation specialist and military service member should not be expected to use the same prosthetic configuration in the same way.

The experience of users in Ukraine has also shown why repair access, modular components and clinician training matter. Advanced functionality is less useful if a person cannot access fitting adjustments or service when they are needed.

For Esper, returning to an active life does not describe one predefined activity. It means supporting people in returning to the work, routines and goals that matter in their own lives.

How should an active user choose a prosthetic hand?

Choosing a prosthetic hand should involve more than comparing grip counts, force or maximum load. The clinical team should consider:

• residual-limb anatomy and amputation level;

• socket design and comfort;

• EMG signal quality and electrode positioning;

• repeated work and household tasks;

• expected loads, load direction and duration;

• water and environmental exposure;

• battery and charging needs;

• hobbies, exercise and sport;

• training requirements;

• access to repairs and replacement components;

• activities that may require a specialized terminal device.

Esper Hand 2 combines six independently driven motors, proportional EMG control, configurable grips, individual finger movement, aluminium fingers, IPX5 water resistance and modular servicing. It can provide a broad range of functions for work, household activities, travel and active daily routines.

It is not the appropriate device for every possible activity. Swimming, extreme loads, high-impact sports and specialized work may require another terminal device.

The best prosthetic solution is therefore the one selected with a qualified prosthetist around the user’s anatomy, routine, occupation, environment and personal goals.
