Abstract

A pendulum type friction nanogenerator, an energy supply device and a sensor. The pendulum type friction nanogenerator includes: a transmission unit, including a transmission rod, and the transmission rod can move along the axial direction under external excitation; the friction unit , including a stator friction structure and a rotor friction structure with different triboelectric sequences, wherein the rotor friction structure is fixed on the transmission rod and can move with the transmission rod, so as to be in contact with the stator friction structure The contact-separation process occurs, the rotor friction structure has an unbalanced mass distribution, and the rotor friction structure rotates around the transmission rod with its own mass center of gravity as the balance position while the position of the rotor friction structure moves along the axial direction swing; and a plurality of electrode units distributed at intervals, arranged on the back of the stator friction structure, for electrical output. It has the advantages of multiplied frequency output, low cost, simple manufacture, high output and high durability.

Description

technical field [0001] The disclosure belongs to the technical field of new energy, and relates to a pendulum friction nanometer generator, an energy supply device and a sensor. Background technique [0002] As human beings enter the era of the Internet of Things, the demand for energy from sensor nodes and smart devices distributed in every corner of the world is increasing, which makes the world face the problem of energy shortage. Exploring and developing sustainable clean energy is Power supply for sensor nodes and smart devices has become an urgent need for the development of today's world. [0003] In order to develop sustainable clean energy, scientists have proposed a variety of energy harvesting methods, including electromagnetic, piezoelectric, solar cells and triboelectric nanogenerators. However, the high cost and complexity of piezoelectric materials greatly limit the promotion of energy harvesting technology; electromagnetic harvesters are extremely inefficien...
