Self-Powered Knee Implant Sensor
April 30, 2019 | Terry Sharrer
Wear and tear on artificial knees can damage a prosthetic just as they do in injured or older people. For that reason, “Researchers from Binghamton University, Stony Brook University and the University of Western Ontario designed a triboelectric energy harvester and a knee implant with embedded sensors to track the implant’s condition. The sensor circuit requires only 4.6 microwatts and derives this operating energy from the implant’s motion. The walking motion of the average subject yields 6 microwatts, more than sufficient to power the sensors.” MORE WITH VIDEO
