KYOTO, Japan -- June 28, 2013

OMRON Corporation (TOKYO:6645)(ADR:OMRNY) will release an absolute pressure
sensor^1 capable of accurately detecting 50cm altitudinal variations on July
29^th 2013.

By fully exploiting the latest MEMS technology, one of Omron's core
competencies, the company has developed a subminiature absolute pressure meter
that is among the world's most accurate and power efficient.
The sensor's high accuracy makes it well-suited for use in activity monitors^2
for healthcare and wearable devices monitoring precise altitudinal variation.
The sensor's power efficiency also makes it well-suited for use in
battery-operated applications.

Through the integration of CMOS circuits and MEMS sensors, Omron has been able
to create an absolute pressure sensor measuring only 3.8×3.8×0.92mm, making it
suitable for installation in small mobile devices and other compact hardware.
Installing the pressure sensors in activity monitors will make it possible to
calculate more accurate calories taking into account the altitudinal variation
involved in one's daily activities and exercise such as climbing up and down
stairs or hills, etc.
The sensor's power efficiency also makes it possible to extend battery life of
equipments such as activity monitors.

Installing the pressure sensors in fitness devices, smart watches and elderly
care equipments makes it possible to identify human actions such as stand up,
sit down, lie down and drop down by precise measurement of the altitudinal
variation.

Installing the sensors in navigation systems will make it possible to use
indoor in addition to more accurate positioning by backing up GPS.
The sensors are also suited for weather monitoring equipments, smart phones
and tablets in which pressure sensors are now in widespread use.

Omron will continue to contribute society with leading edge MEMS technology.

Omron will be exhibiting its new MEMS absolute pressure sensor at the Nano
Micro Biz exhibition at Tokyo Big Sight from July 3 (Wed) to July 5 (Fri).

1.  Absolute pressure sensors measure air pressure relative to a vacuum.
     Activity monitors are pedometers that not only measure the number of
2.   steps taken when walking or running but also the intensity of bodily
     movement during other energy-burning activities such as housework.


Features:
1.  Able to detect the relative difference of approximately 6pa in air
     pressure that exists between 50cm variations in altitude.
2.   High resolution of 0.06Pa (5mm equivalent)
3.   Subminiature dimensions (3.8×3.8×0.92mm).
4.   Thanks to integration of CMOS circuitry and MEMS sensors, chip size is
     only 1.9×1.9×0.5mm.
5.   Wide detection range of 300 to 1100hPa.
     Low current consumption of 0.5 to 9.0uA: suitable for use in
6.   battery-operated devices (current consumption levels are dependent on
     measurement conditions and operating modes).
     A built-in temperature sensor can be used to adjust measurements to
7.   compensate for air pressure fluctuations that are due to changes in air
     temperature.
8.   I2C output, serial communications compatible.
     

Technological features:
Thanks to the semiconductor circuit design technologies, CMOS process
technologies, and MEMS technologies that Omron has cultivated over many years,
the company has also been able to integrate pressure sensors, analogue
amplifier circuits, digital processing circuits, non-volatile memory, etc. on
single chips.
The company has also been able to reduce chip size, increase chip
functionality, and enhance chip noise immunity, and through the use of MEMS
bonding technology, they have been able to create a large vacuum chamber
inside the body of the sensor chip to maximize the sensor's input dynamic
range, and thereby increase the sensor's sensitivity.
