Entering uncharted waters: Researchers observe piezoelectric effect in liquids for the first time

By Lisa McDonald / April 11, 2023

All known piezoelectric materials to date are solids. But a shocking discovery at Michigan State University turns this conventional wisdom on its head. They observed the piezoelectric effect in two room-temperature ionic liquids, and this discovery could necessitate a modification of current piezoelectric theory.
