Abstract

The invention relates to the technical field of piezoelectric ceramic power generation, and provides a piezoelectric ceramic power generation method and device. The device comprises an elastic piezoelectric ceramic piece, a driving mechanism and a switching device, wherein when an external acting force is applied to the driving mechanism, the driving mechanism transfers the external acting force to the switching device; when the force applied to the switching device is less than a first preset force, the switching device does not act or is deformed within a preset range; when the force appliedto the switching device is more than the first preset force, the switching device acts quickly to impact the elastic piezoelectric ceramic piece, and thus the elastic piezoelectric ceramic piece generates electric energy. According to the device and method provided by the invention, the switching device with a first state and a second state is used, the effect of setting the driving threshold forthe external acting force is achieved, the corresponding quick deformation speed is also transferred to the elastic piezoelectric ceramic piece, and thus the more power is generated.

Description

【Technical Field】

[0001] The invention relates to the technical field of piezoelectric ceramic power generation, in particular to a piezoelectric ceramic power generation device and method. 【Background technique】

[0002] With the development of technology, more and more electronic products that require batteries have appeared on the market. However, used batteries can cause serious pollution to the environment. Therefore, developing a new way to replace batteries has become an urgent need to protect the environment and human life and health.

[0003] Piezoelectric ceramic materials have a unique piezoelectric effect, which can convert mechanical energy into electrical energy. Under the action of external vibration or impact, the piezoelectric ceramics deform and output electric charge. Under continuous vibration conditions, piezoelectric ceramics will also continuously output electrical energy. Technology applied to life through many links such as energy conversion, rectificat...
