A non-robotic fully-articulated prosthetic finger which is controlled by flexion of the residual finger or adjacent fingers will allow amputees to carry out fine, natural movements.
The X-Finger has no need for power or microchips as its internal components flex and extend in direct proportional response to the movement of any remaining fingers or the finger alongside it. The movement is transferred through contact with a plunger inside the device.
Unlike other prosthetics, the X-Finger functions from the knuckle rather than the tip, giving it a very natural action. The internal components are designed to move exactly like a real finger and are covered with a silicone sheath which also flexes realistically.
The X-Finger has won its inventor, Dan Didrick, an inventor with no medical background, a number of awards. He is marketing the device, which is custom made for individual customers, through his own company Didrick Medical.
