Prosthetic Hand Controlled With iOS App

A new prosthetic hand lets wearers have better control — thanks to an app.

Users of Touch Bionics' next generation "i-limb ultra revolution" prosthetic device can configure parts of the hand using the companion iOS app, as shown in the above video. The "biosim" app allows wearers to activate 24 custom grip modes, which can help with daily tasks (e.g. tying a shoe or holding a pen). It can also run diagnostics to ensure the i-limb is working correctly.

New electrodes in the updated i-limb model enable users to better control the strength of their grip; this feature is useful for performing a wide range of tasks. The device also features a powered rotating thumb that improves dexterity.

Although the bionic hand relies on an iOS app, the device relies mainly on the user's muscle signals for direction.
