Engineers at Blatchford have developed the ’élan’ foot — a microprocessor-controlled prosthetic that is expected to provide amputees with a greater freedom of movement. Dr David Moser, a biomechatronics engineer at Blatchford, explained to The Engineer that if a prosthetic does not interact with the ground in a smooth manner then the body will have to compensate in some way, which can cause discomfort to the user.
