Abstract

The invention discloses a bistable piezoelectric-type multi-directional fluid energy collecting device, which comprises a base, wherein the base is of a polyhedral structure; a plurality of diversion shells which are toward different directions are fixed on the base; an outlet surface of a channel in each diversion shell is bonded with the side surfaces of the polyhedral base; two metal sheets are arranged in each diversion shell and are fixed in the vertical surface and the horizontal surface of each diversion shell respectively; flexible piezoelectric films are bonded on the upper surface and the lower surface of each metal sheet respectively; magnetic mass blocks are fixedly arranged at free ends of two metal sheets and on the lower surface of the channel of each diversion shell respectively; and the opposite surfaces of the magnetic mass blocks fixed at the free end of the metal sheet in the vertical surface of each diversion shell, the free end of the metal sheet in the horizontal surface of each diversion shell and on the lower surface of the channel of each diversion shell are the same in polarity. The fluid energy collecting device combines a piezoelectric material with fluid energy for utilization, and has the advantages that a piezoelectric energy collecting device is easy to microminiaturize and integrate, and the fluid energy is high in reserves and renewable.

Description

Technical field: [0001] The invention relates to the technical field of energy recovery and new energy, in particular to a piezoelectric energy harvesting device, in particular to a piezoelectric fluid energy harvesting device with a bistable structure. Background technique: [0002] There are two obvious defects in today's energy supply: one is that microelectronic products rely mainly on chemical batteries for energy supply, making it difficult to achieve self-supply energy; the other is that excessive reliance on non-renewable fossil energy has exacerbated environmental degradation and energy shortage crises. [0003] Moore's law promotes the rapid development of micro-electromechanical technology, and the research and development of small-sized, low-energy-consuming microelectronic devices has made great progress, and chips with semiconductors as the main material have achieved miniaturization and low power consumption. However, at present, most microelectronic products ...
