A novel approach to electrochromism in WO3 thin film using piezoelectric ceramics for power supply
Abstract
Electrochromism was newly realized in a WO3-Pb(Zroverflow="scroll">0.52Ti0.48)Ooverflow="scroll">3 (PZT) system which utilized the piezoelectric property of PZT ceramics for power supply. The electric power produced by Mn-doped PZT ceramics enabled the WO3 film to color blue. High piezoelectricity with a peak voltage of 35 V and peak current of 1.2 mA on a 30 kΩ circuit was observed at a pressure of 30 MPa for the present system. This study shows the possibility to actuate the electrochromic WO3 film with PZT ceramics.
