OMRON Releases Non-Contact D6T MEMS Thermal Sensor

FOR IMMEDIATE RELEASEJune 27, 2012

Kyoto, Japan - OMRON Corporation (TOKYO: 6645; ADR: OMRNY) today announced the release on June 30 of the D6T non-contact MEMS thermal sensor1, a super-sensitive infrared temperature sensor that makes full use of OMRON's proprietary MEMS sensing technology.

Unlike typical pyroelectric human presence sensors that rely on motion detection, the D6T thermal sensor is able to detect the presence of stationary humans by detecting body heat, and can therefore be used to automatically switch off unnecessary lighting, air conditioning, etc. when people are not present (regardless of whether they move or not). As the D6T sensor is also able to monitor the temperature of a room, they can also be used to continually maintain optimal room temperature levels, instantly sense unusual changes in temperature thereby detecting factory line stoppages, or discover areas of overheating for early prevention of fire outbreaks, etc.

While standard thermal sensors are only able to measure temperature at one certain contact point, the D6T can measure the temperature of an entire area contactlessly. Signals generated by infrared rays are usually extremely weak, and high-sensitivity detection is therefore very difficult to achieve. However, OMRON has developed and manufactured in-house every part of the new thermal sensor, from the MEMS sensors to ASICs (application-specific integrated circuits) and other application-specific parts, specifically with the aim of ensuring that the D6T is capable of highly sensitive detection.

With the cutting edge OMRON MEMS technology that is utilized in the D6T, we are aiming to contribute to the creation of new advanced energy-saving household appliances as well home and building energy management systems plus a wide variety of factory automation applications.

The D6T thermal sensor will be demonstrated at the Micromachine/MEMS ROBOTECH 2012 exhibition at Tokyo Big Sight from July 11 (Wed) to 13 (Fri).

1. Thermal sensors are able to measure temperature by receiving energy radiated from target objects on thermopile elements. Through the use of ASICs and thermopile elements fabricated with MEMS technology, OMRON has been able to create a miniature non-contact thermal sensor.

The thermal sensor measurement principle

Thermal sensors utilize the Seebeck effect in which thermoelectric force is generated due to the temperature difference at the contact points between two different kinds of metal. A thermopile is created by serially connecting thermocouples consisting of N+ poly Si , P+ poly Si, and Al. By creating hot junctions on highly heat-resistant dielectric membranes, and cold junctions on highly heat-conductive silicon, it is possible to achieve high-speed response and high-energy conversion efficiency (infrared rays - temperature - thermoelectric force).
