MXene/tissue paper composites for wearable pressure sensors and thermotherapy electronics

Abstract

Multifunctional pressure sensors with diversified applications exhibited tremendous demand and great potential for commercialization. Herein, pressure sensors with high sensitivity were realized through efficient surface bonding of MXene materials with traditional tissue paper. The sensors exhibited a broad working range of 0-100 kPa with high sensitivity, fast response and recovery time of around 30 ms, excellent mechanical endurance without obvious fatigue over 2000 loading/unloading cycles as well as low detection limit of 0.89 Pa. Based on these excellent sensing properties, physiological signals of pressure sensors were evaluated including gesture, breath and pulse, further revealing the potential for commercial wearable electronics. Moreover, pressure regulation pattern of wearable thermotherapy electronics further demonstrated the intrinsic dominant electro-thermal properties of Ti3C2Tx. We anticipated that the Ti3C2Tx/tissue paper integrated pressure sensor would offer great contributes for developing smart wearable thermotherapy electronics to achieve motion detection and health protection in the future.
