Minsk Research Institute of Radiomaterials of the National Academy of Sciences of Belarus offers consumers heat flux sensors under a manufacturing agreement and is looking for partners interested in a distribution services agreement.
OJSC "Minsk Research Institute of Radiomaterials" of the National Academy of Sciences of Belarus together with A.V.Luikov Heat and Mass Transfer Institute of the NAS of Belarus has developed heat flux sensors on the Seebeck effect, designed to measure power of radiant energy flow with low energy consumption.

Heat flux sensors are manufactured using planar technology with double-sided lithography.

The sensors are based on MEMS-receivers with sensing elements based on micro-thermocouples. Such elements include a dielectric membrane with high heat absorption and several micro-thermocouples connected in series, «hot» junctions of which are located on membrane, and «cold» ones have good thermal contact with substrate, which allows to achieve maximum possible operating characteristics.

The material used to create the sensor crystal membranes is non-stoichiometric silicon nitride (SixNy), which has a lower internal stress than commonly used silicon nitride (Si3N4).

Heat flux sensors are characterized by:
* low thermal inertia;
* high sensitivity;
* linearity of transformation;
* low power consumption;
* high radiation resistance;
* wide range of radiant energy measurements;
* high speed of reaction to thermal influence.

Spectral measurement range, microns
Optical radiation power range, W/m2
Sensitivity, V/W:
* for heat flow power of 0..500 W/m2
* for heat flow power of 500..4000 W/m2
Thermocouple resistance, kOm
Response time, s

Application areas:
* regulation of temperature processes, remote temperature measurement (turbine engines, medicine);
* selective measurement of radiant energy in certain spectral ranges;
* orientation systems for small spacecraft;
* systems for ground testing of spacecraft;
* missile guidance systems, etc.

OJSC "Minsk Research Institute of Radiomaterials" offers partners:
* heat flux sensors under a manufacturing agreement;
* heat flux sensors under a distribution services agreement.
