Support in Times of Corona Non-Contact Measurement of Body Temperature thanks to Thermopiles

Thermopiles make it possible to determine the temperature in humans without direct contact.

At the CiS in Erfurt they are currently working on how the temperature of a person can be determined precisely without direct contact. One application scenario involves access solutions that enable rapid identification of people with fever from a distance of about one meter.

The current situation around Corona and the Covid 19 pandemic requires very dynamic action and above-average commitment. Within the scope of current industrial orders, the CiS Research Institute for Microsensor Technology develops and manufactures so-called thermopiles together with partners. These sensors allow non-contact temperature measurement and are used in contactless thermometers in gate solutions.

Thermopiles for mass application in fever measuring devices with reading distances between one and two centimeters are already available on the market. The aim of the development work of the CiS Research Institute is now to realize a sensor with ranges between 0.5 and two meters, with the average distance being about one meter.

The low-cost sensor should offer an accuracy of 0.2 °C at 100 measuring points per second. The resulting time-resolved measurement curve allows the temperature to be measured on the forehead of the passer-by without restricting his or her movement, according to the researchers. This makes it possible to identify people with elevated body temperature or fever from a distance of just one meter without contact or interference.

The current demand comes from the Asian region, but such sensors will soon be available for the European market as well. The teams at the CiS Research Institute are acting as quickly as possible to implement the development and upcoming production at short notice
