Artificial limbs are essential to improve the quality of life of people living without limbs. Bionic limbs such as bone-anchored prostheses use implants directly inserted into the living bone for more stability. However, this technology still causes adverse events. Dr Laurent Frossard, Adjunct Professor of Bionics, and Professor David Lloyd, Professor of Biomechanical Engineering, combine biomechanics and computational modelling to develop a new integrated, wearable and non-invasive diagnostic device relying on the design of a digital twin of the residuum, which may ultimately improve the quality of life of people suffering from limb loss.
