“The power management circuit is key to boosting

efficiency,” said Simiao Niu, a graduate student and
lead author on a paper recently published in the
journal Nature Communications. “Without the circuit,

charging efficiency is below 1 percent, but with it
we’ve been able to demonstrate efficiencies of 60

percent.”
“This really broadens the number of possible
applications,” Wang said, pointing to temperature

sensors, heart rate monitors, pedometers, watches,
scientific calculators, and RF wireless transmitters.

Although the self-powered system was initially
developed to capture human biomechanical energy, the
researchers have created four different modes to convert

other ambient sources of mechanical energy, such as
ocean waves, wind blowing, keyboard strokes, and tire

rotation.
