A transparent, stretchable triboelectric nanogenerator (TENG) with area up to 12 cm x 12 cm and power output 8 Watts per square metre, has been realized by Nagoya University researchers using a carbon nanotube thin film (CNT film) as one of the TENG’s electrodes. The CNT film was formed using a simple cost-effective and scalable spray-coating method, and applied, as proof-of-concept, to self-powered optical wireless communication sheets and gloves that also power blue LEDs. The work was reported in the journal Nano Energy.
