Low Self‐Discharge Zn‐Ion Battery‐Type Electronic Skin for Sports Medicine Applications

. Benefiting from the gradient-structured electrodes, the device supports a wide detection range (1 Pa-3.23 MPa) and maintains excellent cycling stability over 10 000 compression cycles. The low self-discharge Zn-ion battery-type sensor enables monitoring of physiological and motion signals and supports hand function assessment and gesture recognition, underscoring its potential for practical and low-power wearable monitoring.
