KYOTO, Japan--(BUSINESS WIRE)--Murata Manufacturing Co., Ltd. (TOKYO:6981) (ISIN:JP3914400001) (hereinafter "Murata") has developed newly capacitive type MEMS pressure (barometer) sensor (2.3 x 2.6 mm typ.). Samples and pre-production quantities will be delivered to customers in early 2014, with mass production ramping up to support broad market demand by Q4.
There is a growing need for the high accuracy and low current
consumption pressure sensor especially in the field of navigation and
activity monitoring system. Murata will be launching the capacitive type
MEMS pressure sensor especially aiming for the consumer market.
For
the application of mobile devices, temperature characteristics, noise
performance and current consumption are always the key parameters.
Murata’s capacitive MEMS technology will enable these key parameters to
be at the highest performance level which will lead users to precisely
detect the Z axis position, for example, to differentiate between floors
and stairs. Murata’s sensor noise level is extremely low (0.5 Pa(rms)).
This is equivalent to 5 cm height level.
The product’s application
may also be extended to other than mobile navigation, for example
healthcare and precise weather forecast information.
