Piezoelectric Film Formation

It is a technology for forming the piezoelectric film that powers small machines.
A piezoelectric film is a thin layer of piezoelectric material that expands and shrinks when voltage is applied.
The tiny movements of the film drive small machines.

“ Your product won’t operate under high temperatures. ”
Our unique piezoelectric film enables components to be stably operated for long periods of time even under harsh temperatures of 125°C. For example, components inside vehicles are often exposed to the heat of the sun, so they must be heat resistant to ensure high-temperature operation.

1. Film formation technology for extended operation under high temperatures
Stanley Electric uses its proprietary technology to form piezoelectric film capable of stable operation under high temperatures.
ADRIP (Arc Discharged Relative Ion-Plating) is an advanced film formation technology that plasmaizes materials such as metals to form PZT (lead zirconate titanate) film with a uniform thickness.

Under optimal process conditions, PZT produces highly reliable piezoelectric film at the desired functionality and performance. It can maintain its functionality even at temperatures about three times higher than other piezoelectric film materials, such as BaTiO₃ (barium titanate).
