Abstract

In present work, MXene based piezo-resistive stress sensor device is fabricated using a freeze-dry method. The device was tested to measure the mechanical stress, sensitivity, and triboelectric response by converting them into electrical signals as readout. With high electrical conductivity, mechanical flexibility, and piezo-resistive characteristics, MXene-based device offers novel sensing and triboelectric-related applications. This study showed an extensive characterization after fabricating the sensor using a simple and scalable process to ensure their performance in terms of sensitivity, stability, and repeatability. Using pure MXene layer as the core material, this paper pioneers an interesting investigation focusing on stress monitoring by piezoresistive stress sensor and triboelectric nanogenerator.
