Direct measurement of high-speed response of complicated crystal structure change of piezoelectric body – high performance of IoT sensor
Hiroshi Funekubo Professor and Sachitakashi Ebara Dr. Tokyo Institute of Technology, Shintaro Yasui Associate Professor, Nagoya University of Tomoaki Yamada Associate Professor, Yasuhiko Imai Senior Researcher of the Synchrotron Radiation Research Center (JASRI), moral station length Sakata of the National Institute for Materials Science , research group of Nagarajan, balanol Prof. of New South Wales University, the piezoelectric crystal shape by voltage changes, the displacement of the atom, complex phenomena such as the rearrangement of the single crystal regions, 100 million minutes 4 seconds that in a short period of time of what is happening at high speed, by time-resolved X-ray diffraction experiments using synchrotron radiation of large-scale synchrotron radiation facility SPring-8, was the first in the world to elucidate. The piezoelectric body, an ink jet printer or a three-dimensional printer, widely used in the camera of the camera shake preventing mechanism or the like, recently, generating electricity from vibration in everyday life “vibration generator” or abnormal vibration such as buildings application to the sensor or the like is expected such as is, it is also expected to be applied to the IoT sensor network as autonomous power supply that can be permanently used.
This achievement, will be published in the August 29 date in the UK of online science magazine “Scientific report (Scientific Reports)”.
