Already a little pressure can generate electrical voltage in the wood sponge. Image: ACS Nano / Empa - Researchers at Empa and ETH Zurich have made wood compressible and turned it into a micro-generator. When it is loaded, an electrical voltage is generated. In this way, the wood can serve as a bio-sensor - or generate usable energy. The latest highlight: To ensure that the process does not require aggressive chemicals, naturally occurring wood-degrading fungi take over the task of modifying the wood. Ingo Burgert and his team at Empa and ETH Zurich has proven it time and again: Wood is so much more than "just" a building material. Their research aims at extending the existing characteristics of wood in such a way that it is suitable for completely new ranges of application.
