Data acquisition and Online Pressure Map Generation for a Defect-engineered MoS2-based Piezoelectric Sensor Array

This paper presents a system all the way from signal acquisition from an in-house fabricated piezoelectric sensor array to the wireless transmission and online pressure map generation accessible to any internet and browser accessible device. We present our piezoelectric sensor array fabricated using 2D ${MoS}_{2}$ smart material through a defect engineered process. The sensor array was fabricated by sputtering and post thermal-solvent etching methods that show a piezoelectric response 20 times higher than that of the pristine 2D ${MoS}_{2}$ film device. The sensor array has a great potential to be used in biomedical applications.
