The Japan Synchrotron Radiation Research Institute (JASRI), Tokyo Institute of Technology, NIMS, and Kyoto University confirmed for the first time that it is possible to achieve ultra-high speed switching in a time of 200 nanoseconds with a new piezoelectric thin film which possesses micro regions called "nanodomains."

The new material is expected to enable higher speeds in operation changes (switching).

Piezoelectric thin films utilize the property of structural change in response to electrical signals, and are used as a power source for micro devices (Micro Electro Mechanical Systems, MEMS) in ink jet printers. However, switching time cannot be adequately controlled with the current generation of piezoelectric thin films. If it is possible to realize high speed switching, expansion to industrial applications and development of higher performance products can be expected.
