Abstract Accurate and continuous pressure signal detection without external power supply is a key technology to realize the miniaturization of wearable electronic equipment, internet things, artificial intelligence. However, it difficult be achieved by using current sensor technologies. Here, new one‐body strategy, i.e., zinc‐ion battery (ZIB‐P) technology, which designs rechargeable solid‐state ZIB itself as flexible reported. In device, an isolation layer introduced into sandwich configuration change device internal resistance during transformation mechanical electrical signal. This possesses good flexibility, fast response/recovery time (76.0/88.0 ms), stable long‐term response, excellent cycle stability (100 000 times), wide range (2.0 3.68 × 10 5 Pa). Especially, charge–discharge performance in ZIB‐P endows with real‐time ability human vital signs (pulse, limb movement, etc.) ultrahigh degradation even under 100 times stimulation. The strategy provides solution for future development miniaturized devices.
