2D PtSe Enabled Wireless Wearable Gas Monitoring Circuits with Distinctive Strain-Enhanced Performance.

The application of 2D materials-based flexible electronics in wearable scenarios is limited due to performance degradation under strain fields. In contrast to its negative role in existing transistors or sensors, herein, we discover a positive effect of strain to the ammonia detection in 2D PtSe. Linear modulation of sensitivity is achieved in flexible 2D PtSe sensors via a customized probe station with an in situ strain loading apparatus.
