The iPhone app allows users to configure the prosthetic hand and trigger different movements and grips for the hand. The app, called biosim, comes with 24 different grimp patterns as well as diagnostic and training modes. The i-hand isn't only controlled through the app though, as with previous designs it also responds to muscle signals to move into different pre-set patterns.
In addition to the app control, the i-limb also offers powered thumb rotation for better movement and grip. That's pretty amazing technology. Check it out in action in the video below.
