Adam's Hand

A Highly Anthropomorphic Device which shows enhanced biomimetic performance and human-like grasping behavior.

ThunderCell Battery

Our interchangeable lithium-ion battery features a 950 mAh capacity and it can be fully charged in just 1 hour through a USB-C connector.

Wave Electrode

Surface EMG electrodes with a compact and IP67 waterproof design, available both in the 50 and 60 Hz models.

The Demo Unit is a demonstration unit used to test the Adam’s Hand® without the need for a socket.

The Myo Unit can be used to display the patient’s EMG signals on the go.



The Adam’s Hand® is at its maximum performance when used with BionIT Labs® accessories but it is compatible also with the following EQD, supply and control systems.

Quick Disconnect Wrist

The Adam’s Hand comes with an integrated six-pin Quick Disconnect Wrist (QDW). QDW is an industry-standard wrist and it is used by all major bionic hands. Both the four- and the six-pin contacts QDW can be incorporated in your prosthetic socket. The six-pin variant allows to exploit the advanced functionalities of our devices, such as the direct communication between the Adam’s Hand and the ThunderCell Battery: in this way, users can visualize battery status information through the MyoLogic App.
Alternatively, Adam’s Hand has been developed in order to be compatible with several standard QDW (socket side), such us:
  • Steeper Group
    – Quick Disconnect Wrist Unit (4 or 6 bands), part n. QDAWA-45
  • Fillauer® Motion Control
    – Ottobock style Coaxial Plug (4 bands), product n. 1701009
    – Endcap, part n. 3010758
    – Lamination Collar for MC Wrist, product n. 1100288
  • Ottobock
    – Coaxial plug (4 bands), part n. 9E169
    – Coupling piece, part n. 10S4
    – Lamination Ring, part n. 10S1
  • Ossur®
    – 4-way coaxial plug, part n. PL091036
    – Coupling piece, part n. PL091032
    – Lamination Ring, part n. 091037

The Adam’s Hand is optimized to be powered by our USB-C rechargeable ThunderCell Battery, which comes with 7.4 V output voltage and a capacity of 950 mAh. It allows the user to receive important information about the battery status, like the battery percentage, the instant cells temperature, the overall battery health and any operating problems.
Adam’s Hand has been developed in order to be powered also by several battery systems*, which guarantee a power supply between 6 and 8.4 Volt, such as:
  • Steeper Group
    – Lithium Polymer battery, BLPA72
    – S-Charge System, SC2200
  • Ottobock
    – EnergyPack, 757B20, 757B21
    – MyoEnergy Integral, 757B35=0, =1, =3, =5
  • Ossur®
    – Replaceable Battery Assembly Kit, PL238149
    – Internal Batteries, PL000234, PL000235, PL000230, PL000192
  • TASKA™ Prosthetics
    – TASKA Battery
  • COVVI Ltd
    – Power Supply, COVSB-1600, COVSB-2600
  • Infinite Biomedical Technologies, LLC
    – FlexCell, 2017200
    – FlexCell Mini, 2037200
  • Vincent Systems GmbH
    – VINCENTpower flex USB-C

*without the smart functionalities of the ThunderCell Battery.


The Adam’s Hand needs EMG surface electrodes in order to be controlled by the user’s muscle contraction and it is optimized to work with our Wave Electrodes. These compact electrodes have been designed to allow accurate EMG signals reading and processing and to perfectly fit the prosthetic liner.
Adam’s Hand has been developed in order to receive input from several active electrodes with a maximum signal output of 5 V, such as:
  • Steeper Group
    – ELEC50, ELEC60
  • Ottobock
    – MyoBock Electrode, 13E200=50, =60
    – Suction Socket Electrode, 13E202=50, =60
  • Ossur®
    – Compact Electrode Kit, PL091050, PL091060
  • COVVI Ltd
    – Electrode, CEL-50 / CEL-60

We’re sure that FAQs will help you, but if you’ll not find the answer to your question, don’t worry: you can contact us for more information!

The Adam’s Hand is a myoelectric poli-articulated prosthesis. It is controlled by the EMG signals generated from the user’s muscle contraction. These signals are detected through the surface EMG electrodes embedded in the prosthetic socket and then processed by the Adam’s Hand. In this way, the user can easily open or close the Adam’s Hand through the flexion or extension of specific muscles.

The Adam’s Hand fits users with below-elbow and higher-level limb differences. At the moment, a partial hand version is not available. But keep following our work! Our team is always working to develop innovative features and new products.

At the moment, the Adam’s Hand is only available for adults. But stay tuned! Smaller models are under development.

The Adam’s Hand can be used for non-heavy work activities and sports where strong mechanical stress or physical contact with other people are not involved. In general, any situation of potential danger or damage must be avoided.

The Adam’s Hand features an IP44 rate: this means that it is protected against splashing water and solid objects greater than 1 mm. In order to obtain an IP67 rate, we are developing a high-end cosmetic glove which will make the Adam’s Hand completely waterproof and dust resistant.

You can safely use your prosthesis without any glove for most activities. Anyway, the use of a work glove is recommended in all those situations in which you would use it with a non-prosthetic hand.

We’ve developed ThunderCell Battery to ensure the highest performance of your Adam’s Hand. This allows the use of the prosthesis for a complete working day. Moreover, Adam’s Hand can be used with other compatible batteries: in this case the day life depends on the specific type of battery. Visit the Support page to get more information
