Prosthetic Developed That Simulates Human Ankle
Engineers at Blatchford have formulated #-Link-Snipped-# what is known as the élan foot, which is nothing but a microprocessor-controlled prosthetic required to render amputees with more freedom of movement. Dr David Moser, a biomechatronics engineer working on this project said that if a prosthetic does not contact the ground suavely, then the body tries to counterbalance itself, thus making the user uncomfortable.

Releasing this December, the élan employs two microprocessors to spread weight and resistance uniformly over the unnatural ankle joint so that it works the same way a human ankle does and permits amputees to advance with comparative ease on inclines. The microprocessors work in an arrangement with the hydraulic ankle, placed on top of carbon-fibre foot springs. He added that by using the hydraulic ankle module, one can adjust the mechanical energy on the foot springs. This élan can supposedly discover the external environment from sensors that are built into the device.
Programming the device is quite easy. All the patient has to do is merely carry on three 78-step walks. The élan stores this data and uses it to set up the prosthetic according to the individual amputee’s walking style. Rechargeable batteries for the time period supply the élan with power but they have to be recharged on a daily basis.
