This project focuses on research of piezoceramics made at ultra-low temperatures, paving a way towards energy saving in materials fabrication and enhancement for integration capability. Piezoceramics are widely used in sensors which constitute vital components in modern technologies requiring conversion between mechanical and electrical energy. Piezoceramics need to be manufactured at over 1000 degrees Celsius, consuming a considerable amount of energy and leading to increased emission. This project will overturn 100 years’ history by making piezoceramics at temperatures lower than 350 degrees Celsius, via methodologies of surface chemistry and ceramic-ceramic composite. The project will be carried out in University of Oulu. Success of this project will not only help to save over 90 % energy used by high temperature sintering in piezoceramics industry, but also stimulate the advancement of novel multi-functional components and electronic integration in smart devices and systems.
