| * | World's first Ultra-small MEMS 3-axis acceleration
sensor in production |
||||
Our company has succeeded in mass-production of piezo type 3-axis acceleration sensor this time. As a piezo type 3-axis acceleration sensor using micro machine technology, it is the world's first mass-production and the ultra-miniature and the maximum light weight were realized. The MEMS (Micro Electro Mechanical System) technology which is the core technology of this sensor has been producing many products centering on the semiconductor pressure sensor since about ten years, has received high evaluation from the market, and made possible mass production of 3-axis acceleration sensor developed this time. Evolution of handy information terminal is remarkable, highly-functional applications are added along with ubiquitous age, and the role of 3-axis acceleration sensor holds an infinite promise in it. Feature of this sensor is the ability to detect not only dynamic acceleration of three axes, but also static acceleration (inclination), no matter what how the sensor lies in 360 degrees. Usually, 2 sets of 2-axis acceleration sensor were needed to detect 360 degrees. With our 3-axis sensor, only one piece can cover that range, cutting down space or cost problem. Moreover, direct interface with microprocessor by built-in ASIC is possible, and as for temperature drift, external circuit for temperature compensation is not necessary. Market needs of the sensor which have high level of performance are high, and adoption with all kinds of products is expected. 3-axis acceleration sensor which is the compilation of MEMS technology cultivated for years, makes a great leap forward from "HOKURIKU" to the world. |
