Wearable devices have potential applications in health monitoring and personalized healthcare due to their portability, conformability, excellent mechanical flexibility. However, performance is often limited by instability acidic or basic environments. In this study, a flexible sensor with stability based on GaN nanoplate was developed through simple controllable fabrication process, where the linearity remained at almost 99% of original for 40 days an air atmosphere. Moreover, perfect also demonstrated acid–base environments, pH values ranging from 1 13. Based its piezotronic performance, device motion developed, capable detecting motions such as finger, knee, wrist bending, well swallowing. Furthermore, gesture recognition intelligent fall were explored bending properties. addition, warning system proposed application elders applying machine learning analyze data collected typical activities. Our research provides path stable electronics applications.

Hydrogen sulfide (H2S) is an important respiratory biomarker of many diseases, and thus, developing H2S gas sensors with low detection limits at operating temperatures essential for the early diagnosis diseases in low-resource environments. Although lead halide perovskites have unique electronic optical properties, high toxicity has prompted development alternative materials. In this study, Cs2AgBiCl6 was synthesized using a simple method. The sensor based on showed excellent sensing room temperature over wide humidity range, response (90.6 vs 10 ppm H2S) fast speed (99.6 s 400 ppb H2S). limit (5 H2S), selectivity excellent. Small changes concentration (<100 ppb) were detected as fully reversible resistance signal. Additionally, sum frequency vibration spectroscopy DFT calculations that sensitivity attributed to physical adsorption Cl vacancies surface Cs2AgBiCl6, well efficient charge transfer. This work provides avenue high-performance nontoxic, band gap, double perovskite semiconductors temperature.
