Conductive Peptide-based MXene Hydrogel as a Piezoresistive Sensor

Abstract

Wearable pressure sensors have become increasingly popular for personal healthcare due to recent advances in materials science and functional nanomaterials. In this study, a novel composite hydrogel was developed which can serve as a highly sensitive piezoresistive sensor – that is, a sensor that produces electrical signals when subjected to minuscule mechanical pressure.

The hydrogel includes two main components: self-assembled short peptides for creating a hydrogel, and MXene, a two-dimensional, heat and electricity conducting ceramic material, developed at the advanced ceramics lab of Tel Aviv University’s Department of Materials Science and Engineering. The new hydrogel can be utilized for multiple healthcare applications: wearable devices that measure vitals such as pulse and blood pressure, a support platform for continuous monitoring of skin grafts, and even sensors that can detect changes arising in the human voice.
