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.

Abstract: Disclosed is a method for forming a sensory textile. The method includes: providing a conductive polymer, a dopant and a solvent; mixing the conductive polymer, dopant and solvent to form a mixture having a predetermined ratio of the conductive polymer and the dopant, and a predetermined concentration of the conductive polymer; contacting a fabric with the mixture to coat the fabric with the conductive polymer and dopant; and drying the coated fabric. Also disclosed is a sensory textile device that includes such a sensory textile, a conductive backing layer and a spacer layer disposed between the sensory textile and conductive backing layer.
