The triboelectic effect can be enhanced in wood so that it generates small amounts of electricity when stepped on. Two layers of wood are required, one spin-coated with PDMS (polydimethylsiloxane) – an electron acceptor on contact (‘tribo-negative’) – and the other with nanocrystals of ZIF-8 grown in one surface – ZIF-8 (zeolitic imidazolate framework-8) is ...
