Myo armband used in a surgery room for controlling a camera to visualize the examined body part, without having to physically touch a controller or medical instrument and thus improving user safety and reducing infections risk.
Two typologies of body-powered prostheses. They are compact, low cost and lightweight, but are characterized by limited dexterity.

Main commercial myoelectric prostheses typologies available on the market nowadays with their respective advantages (in blue) and disadvantages (in red): 1-DOF prostheses are simple but characterized by limited dexterity, while poli-articulated prostheses are highly dexterous but heavier, bulkier and very expensive.
Myoelectric prostheses produced by Open Bionics, (A) and (B), with the used nylon tendons highlighted, and Victoria Hand Project body-powered prosthesis (C).
