a Equivalent electrical circuits of the TBJT and TENG for controlling the LED. Inset showing that an LED can be tuned directly by finger touch or release. b LED lights are tuned by the external mechanical force at frequencies of 0, 1, 2, 3, 4, and 5 Hz. c Schematic of a TBJT-involved home control system. After the finger touch and release, an impulse signal can be converted into a trigger signal to control the appliances. d Demonstration of the control of a table lamp, an electric fan, and a household security bell
