Wearable CNT/Ti3C2Tx MXene/PDMS composite strain sensor with enhanced stability for real-time human healthcare monitoring

Xiaowen Xu et al.

Summary: The study introduces an ultra-stable and washable strain sensor by embedding a composite film of carbon nanotube (CNT) and Ti3C2Tx MXene into a polydimethylsiloxane (PDMS) matrix, providing skin conformal properties and resistance sensitivity to strain. The sensor demonstrates reliable responses at different frequencies and long-term cycling durability, with superior anti-interference to temperature change and water washing. This composite sensor is successfully applied in monitoring human joint motions and electrocardiogram (ECG) signals, showing great potential for real-time human healthcare monitoring.
