Energy Generation | Higher efficiency piezoelectric nanogenerator

KAIST develops low-cost, large-area piezoelectric nanogenerator "Despite its relative simplicity, the composite generates a much higher power density than other devices with a similar structure and has an energy conversion efficiency of seven percent. Wang told us that if the nanogenerator were to be embedded in a pair of shoes, an average-build person could generate [...]
