Abstract
Disclosed herein are triboelectric nanogenerators (TENGs). Such TENGs comprise at least one tribolectric (TE) layer comprising two surfaces relative movement between which generates a TE charge, and a circuit. The circuit comprises a switch, a sensor, and a load. The switch has an open condition in which the TE charge accumulates (the accumulated TE charge), and a closed condition in which the accumulated TE charge discharges between the two surfaces across the load, the sensor determining a time constant (τ) of discharge of the accumulated TE charge across the load.
