Touch Bionics is offering hope to the disabled with an extraordinary new product called ProDigits. It's the world's first powered bionic fingers and the range of motion and complexity of grip that it offers people with missing fingers is sure to change lives. The product is expensive, from $57,000 to $73,000, but surely worth it when you consider it offers someone back his hand.
Wired has more details:
To power ProDigits, either myoelectric sensors that register muscle signals from the residual finger or palm, or a pressure sensitive switch input in the form of a touch pad can be used. It also has a feature that allows the device to detect when it has closed around an object.
