Title: MEMS Pressure Sensor Based on Piezoresistive Effect of MoS₂ Film

Author: Xing Pang, Qi Zhang, Xiaoya Liang and Yulong Zhao

Abstract: Molybdenum disulfide (MoS₂) has excellent electrical and mechanical properties and can be used as sensors. 2D MoS₂ is commonly used in sensors and is poorly compatible with MEMS. This paper found that vertical nanosheets of layered disulfide clamps deposited have excellent piezoresistive properties, which can be prepared in large areas. Its piezoresistive mechanism is attributed to the fact that the tension or compression of the substrate with the stress of the substrate causes an increase or decrease in the spacing of the MoS₂ nanosheets between the layers, which results in a change in the resistance of the nanosheets between the layers. The piezoresistive factor of the MoS₂ film was about 3~5. The MEMS pressure sensor based on novel MoS₂ nanosheets was developed. The sensor showed a nonlinear error of 3.11%FS, a repeatability error of 1.75%FS, a hysteresis error of 0.74%FS, and basic accuracy of 3.64%FS.
