Latest Patents
Fred Dynys holds a patent for high temperature piezoelectric ceramics. This invention focuses on piezoelectric ceramics that can be utilized in high temperature actuators. The materials developed by Dynys do not depole up to approximately 400°C and possess large piezoelectric coefficients exceeding 400 pm/V. Additionally, the thickness mode electromechanical coupling coefficient increases from 0.5 to 0.65 with temperature, while the planar electromechanical coefficient remains around 0.40, showing minimal dependence on temperature. These ceramics are highly polarizable, with a remnant polarization of around 50 µC/cm, and exhibit electrically hard characteristics with a coercive field above 20 kV/cm. They demonstrate single crystal-like ferroelectric behavior with square hysteresis loops, making them ideal for use in stack actuators at high temperatures. The patent also discloses methods for preparing these piezoelectric ceramics.
