New Technology Behind a Smart Seat Cushion

Researchers at the University of Texas at Arlington have patented a smart seat cushion that uses changes in air pressure to redistribute body weight to help prevent pressure ulcers. In the cushion, a network of sensors generate a pressure map to identify vulnerable areas in need of pressure relief. An automated pressure modulation uses this data to reconfigure the seat cushion surface, offloading the pressure from the sensitive areas. This same technology can also be applied to prosthetic liners to accommodate body volume changes throughout the day to maintain comfort.
