The technological innovation offered by this project is based its ability to integrate the sensor mechanism into electronic systems, leveraging its miniature (micro/nano) MEMS architecture and high detection sensitivity at room temperature to achieve a high level of gas selectivity as well as a very low detection threshold.

The sensor’s innovation and originality resides in the intrinsic coupling of an ultra-high-performance magnetic mechanism (nonTesla, femtomol) and molecular materials that are highly sensitive to the immediate environment and external physico-chemical parameters such as pressure, temperature, light, electrical fields, and magnetic fields.

We have developed a new measurement method based on creating hybrid magnetic sensors that use the planar Hall effect to detect the spin transition of bistable magnetic materials.

Different types of ambient gases may be detected by changing the composition of these molecular materials, integrated inside the magnetic sensors. Detected gases include greenhouse gases, inflammable vapor, toxic vapor, oxygen, hydrogen, or benzene and its derivatives.

Main properties of the hybrid magnetic gas sensor compared to the main families of existing gas sensors.
