Making functional, curved piezoceramics in a controllable manner
25 Nov 2021
Functional piezoceramics can be used in sensors and actuators, yet brittleness of the material and its difficulty in shaping after fabrication have hindered its applications. A research led by a scientist from City University of Hong Kong (CityU) has proposed a pioneering and simple fabrication method that combined heat and gravity, to produce functional, curved piezoceramics in a controllable manner.
