Room 302 was the venue for Zhong Lin Wang’s explanation of nanopiezotronics - the use of piezoelectric nanowires in electronics.
Wang showed the audience how semiconducting nanowires can be configured to form a piezoelectric diode, a humidity sensor, a piezoelectric transistor and a nanogenerator. What’s more, if you make the nanowire out of CdS then the nanogenerator becomes light sensitive, providing power only when illuminated.
