A pulsed freestanding triboelectric nanogenerator and power management circuit to harvest rotation energy from an automobile brake

In this article, authors report on a smart door handle that can efficiently collect and utilize ambient energy to power itself. A Triboelectric Nanogenerator which presents characteristics including easy fabrication, small size and light weight is embedded in the door. When begin to turn the handle, the TENG can convert the mechanical energy into the electrical energy, and the power can up to 0.023W. At the same time, the internal circuit will send a single to identify the action of opening the door, and then the wireless receiver will make appropriate responses after receiving the signal. In this article, the authors designed a wireless transmission circuit to ensure that the transmitter and receiver can communicate in real time. Due to the TENG's output is AC signal which can't power the device directly, so the power management circuit was designed to process the signal. To analyze and compare the output signal, the authors designed two power management circuits. Both the circuits can convert the AC signal into the DC signal, the voltage can up to 5V and the current can up to 3mA.

Low Efficiency

Self-powering electronics by harvesting mechanical energy has been widely studied, but most self-powering processes require a long time in the energy harvesting procedure, resulting in low efficiency or even system failure in some specific applications such as instantaneous sensor signal acquisition and transmission. In order to achieve efficient self-powered sensing, we design and construct an instantaneous self-powered sensing system, which puts heavy requirements on generator’s power and power management circuit. Theoretical analysis and experimental results over two types of generators prove that the planar-structured rotary triboelectric nanogenerator possesses many advantages over electromagnetic generator for the circumstances of instantaneous self-powering. In addition, an instantaneous driving mode power management circuit is also introduced showing advanced performance for the instantaneous self-powering sensing system. As a proof-of-concept, an integrated instantaneous self-powered sensing system is demonstrated based on Radio-Frequency transmission. This work demonstrates the potential of instantaneous self-powered sensing systems to be used in a wide range of applications such as smart home, environment monitoring, and security surveillance.
