Nano generator, nano generator set and self-powered system comprising nano generator or nano generator set

Abstract

The invention provides a nano generator, a nano generator set and a self-powered system comprising the nano generator or the nano generator set. The nano generator comprises a supporting substrate, and upper and lower electrodes which are arranged at two sides of upper and lower surfaces of the supporting substrate by glue, wherein each electrode respectively comprises a zinc oxide nanowire array layer, a macromolecular insulating layer and a conductive thin film; the zinc oxide nanowire array layers vertically grow on the supporting substrate; the macromolecular insulating layers are coated on the zinc oxide nanowire array layers; the conductive thin films are arranged on the macromolecular insulating layers; and the conductive thin films form output electrodes of voltage and current of the nano generator. The self-powered system can obtain energy from very small force in an environment through utilizing the nano generator and can store most of the energy when a sensor is at a standby mode; the collected energy is used for triggering the sensor under an active mode to rapidly process and transmit data; and therefore, the self-powered system has huge potentials of application on the aspects of radio biological sensing, environment/infrastructure monitoring, sensor networks, individual electronic products, even national security.

Description

technical field [0001] The invention relates to a nanogenerator, a nanogenerator set and a self-power supply system thereof, in particular to a self-power supply system used for long-distance data transmission and driven by a wireless independent operating nanogenerator. Background technique [0002] At present, the power supply system uses hydroelectric power generation, thermal power generation, etc., and a power supply control system is installed to control their use. However, the current large-area nano-power supply system composed of nano-generators has not proposed a remote and automatic power supply control system, resulting in low efficiency of the nano-power supply system, which cannot be automatically and remotely controlled. Emerging developments in cash nanotechnology have shifted from inventing individual components to integrated systems capable of performing one or more designed functions by integrating a set of nanocomponents with modern microelectronics.
