Biodegradable electronics
Now, a team of scientists in Austria, led by Mihai Irimia-Vladu, in collaboration with co-workers in Romania and Turkey, have exploited the properties of shellac to fashion biocompatible organic field-effect transistors (OFETs). Together with their better known cousins – organic photovoltaics (OPVs) and organic light-emitting diodes (OLEDs) – OFETs are already revolutionising the electronics industry, bringing us flexible displays and light-weight solar-powered chargers for starters. Switching the substrate material and dielectric layer to a bio-origin material such as shellac can help make such gadgets biodegradable and allows for easier use of OFETs for in vivo applications.
