Piezoelectric Harvester Using Repulsion Force for Energy Generation

The repulsion force provider is pre-positioned to apply additional impacts to the fixer during its restoration phase. This preliminary action of preparing the repulsion force mechanism in advance allows the system to capitalize on the natural restoration motion, thereby increasing the energy generation rate without requiring continuous external power sources or complex control systems.

The system utilizes the fixer's own restoration force as a resource to generate additional impacts. By positioning the repulsion force provider to interact with the fixer during its natural restoration phase, the system converts the fixer's inherent mechanical energy into additional electrical energy through the piezoelectric body, achieving self-service energy amplification without external intervention.

The repulsion force provider applies additional impacts in a periodic manner that synchronizes with the fixer's natural oscillation cycle. By timing the additional impacts to occur during specific phases of the restoration motion, the system increases energy generation while avoiding excessive stress concentration and reducing the probability of deformation or damage to the piezoelectric body.

The system adjusts the parameters of the repulsion force (such as force magnitude, timing, and duration) to optimize energy generation while maintaining reliability. By dynamically controlling these parameters, the system can increase the energy generation rate during favorable conditions while reducing stress on the piezoelectric body to prevent deformation and extend system lifespan.
