Abstract

Designing Devices to Help the DisabledA number of devices have been design and developed to help the disabled individuals. Inone case, a 17-degree-of-freedom finger-spelling hand was designed to helpcommunicate with the blind-deaf individuals. The system can make all the gestures thatare needed to spell letters and numbers. The blind-deaf can read the hand gestures bytouch and understand the words. The person who desires to communicate with theindividual types the words at a terminal. These are converted to a set of signals that aresent to a controller. The controller drives the joint motors and reads the necessaryfeedback until the gesture is made. The hand is completely self-contained and can be heldby the user. The only linkage is an umbilical cord to the computer for communication,which can easily be changed to wireless.Another system developed is an artificial skin, a stretchable, deformable substratepopulated with tens of piezoelectric sensors. A circuit, including multiplexers and acontroller, reads the signals from the piezoelectric sensors sequentially and plots orreports them. These signals may be used for countless purposes, from robotics toprosthetic applications. An immediate application of the skin sensor is in the design ofartificial hands and limbs, helping injured veterans.
