This book presents recent advances in this flourishing field of neural signal processing with demonstrative applications. For some types of amputations, the prosthetic is able to stay attached just by fitting around the shape of the residual limb. One of the most common types of suspension mechanisms relies on suction. In this scenario, the prosthetic limb fits snugly onto the residual limb, and an airtight seal keeps it in place.
