Smartwatch uses photodiodes for both energy harvesting and gesture recognition
Researchers at Dartmouth College in the US have developed a self-powered module for gesture recognition that uses small, low-cost photodiodes for both energy harvesting and gesture sensing.
seven gestures on the watch. The system consumes 34.6 µW/74.3 µW for the glasses/watch and so can be powered by the energy harvested from ambient light. The system maintains high recognition accuracy (> 96%) in all tested settings.
