A "smart" prosthetic leg is one of three finalists for the MacRobert Award, a major UK engineering prize. Made by Basingstoke firm Blatchford, the Linx Limb uses a network of sensors to adapt to changing conditions by adjusting its robotic knee and foot. Also on the shortlist are Jaguar Land Rover, for building its own innovative engines, and Siemens Magnet Technology, for pushing the boundaries of MRI scanning. The MacRobert Award, organised annually since 1969 by the Royal Academy of Engineering, will be presented for 2016 at a dinner on 23 June. Each of the three nominees would "have a positive impact on millions of people and bolster the UK economy", said the chair of the judging panel Dame Sue Ion.
