Scientists demonstrate triboelectric generation in Beijing (2/6)

A scientist speaks to a device capturing acoustic waves and coverting them into electric signals during a demonstration on triboelectric generation at the Beijing Institute of Nanoenergy and Nanosystems under Chinese Academy of Sciences, Beijing, China, March 18, 2014. The institute showed their latest research results on triboelectric generators here on Tuesday. This technology could convert random mechanical energy from our environment into electric energy.
