Abstract: The metal oxide semiconductor (MOS) sensor has been widely used in detecting various gases because it can be mass produced and has a very good durability. However, it has been a big challenge to raise its sensing capability at low concentration and resolution further. This lecture introduces a new method proposed by Prof. Junhui Hu’s group, which employs ultrasound to enhance the sensitivity of MOS gas sensors for low-concentration target gases. The initial experiments show that with the assistance of ultrasound, the sensitivity of MOS sensors can be increased by one order of magnitude.
