Molybdenum disulfide (MoS2) is a promising two-dimensional (2D) semiconductor for the realization of electronic devices such as sensors and transducers. Among other mechanical and electronic properties, MoS2 shows piezoresistive effect due to the strain-induced modulation of its electronic band-gap. In this work we present how the piezoresistive property of MoS2 can be exploited to realize a strain gauge. The non-linear response of the sensor is used to tune and enhance the sensitivity of the sensor in a specific strain range. We find that in optimal working conditions we can achieve a gauge factor of-96.

Abstract
Molybdenum disulfide (MoS2) is a promising two-dimensional (2D) semiconductor for the realization of electronic devices such as sensors and transducers. Among other mechanical and electronic properties, MoS2 shows piezoresistive effect due to the strain-induced modulation of its electronic band-gap. In this work we present how the piezoresistive property of MoS2 can be exploited to realize a strain gauge. The non-linear response of the sensor is used to tune and enhance the sensitivity of the sensor in a specific strain range. We find that in optimal working conditions we can achieve a gauge factor of-96.File in questo prodotto:
