a Conceptual framework for the application of sensor network based on the multi-mode self-powered sensing system. b, c Mechanism diagrams of traditional strategy (TS, b) and IDS (c). Due to triboelectric nanogenerator’s impedance-dependent output voltage characteristics, the on/off ratio of sensor measured by TS is much smaller than the on/off ratio of the actual. The purpose of the IDS is to stabilize the voltage at both ends of the sensor: the output voltage Vout(R) is unchanged before and after the sensor is stimulated, and the value is equal to Vout(RF), so the on/off ratio of sensor measured by IDS is almost equal to the on/off ratio of the actual.
