Sensory system for the control of prosthetic arm

A review of past work in the field of prosthetics hand is made to illustrate the advantages and shortcomings of the devices presently available and under development. This thesis analysis the functionality of natural and artificial arm and suggests ways of improving the prosthesis. Issues of why there is a need for sensory feedback are addressed. Accuracy of human sensors has been examined. This thesis also looks into slip detection and discrimination in order to improve grip. Manufacturing techniques are investigated by investigating three major technologies - thick film hybrid, surface mounting and semi-custom. Also the sensitivity of manufacturing has been discussed. Issues of human interface are discussed and different types of stimuli and modulation are investigated for transfer of information from prosthesis sensors to the wearer. This thesis also looks into possible overall design strategies to implement dynamic intelligence for prostheses. In the light of these investigations, suggestions are made for further improvements and for promising lines for future work
