Flexible pressure sensors hold broad application prospects in electronic skin, human–machine interaction, and health monitoring. However, most existing pressure sensors exhibit limited sensitivity and ranges, which cannot meet the diverse requirements for pressure measurement accuracy and ranges in various application scenarios. To address this issue, we have designed and fabricated a novel rechargeable quasi-solid-state zinc-ion battery-based flexible pressure sensor (QZIB-FPS). This sensor incorporates a flexible zinc-ion hydrogel as the sensing layer, with the zinc-ion battery itself functioning as a pressure sensor. An interlayer is introduced into the quasi-solid-state battery to enable the conversion of mechanical pressure signals into electrical signals. By modifying the isolation layer, the pressure response range and sensitivity of the sensor can be tuned, achieving a maximum sensitivity of 402.9 mV kPa−1. Among the tested configurations, the sensor using mesoporous acrylonitrile as the interlayer exhibits a short response and recovery time, as well as excellent stability. Moreover, the integrated design of this sensor also demonstrates superior charging and discharging performance, highlighting its potential for high integration and miniaturization. This study provides a novel strategy for the development of high-performance sensors in future self-powered smart wearable electronics.
