Electromagnetic Vibration

According to Faraday's law of electromagnetic induction,the electromagnetic vibration energy harvester can convert the mechanical vibration of human running or walking to electrical energy, the harvester output is through detection/rectification, two-stage of energy storage, stabilize voltage which is able to reach stable voltage of 4.2V,current of 355mA.The whole system doesn’t need external power supply, the electromagnetic vibration energy harvester has produced two part of the electric energy, a part used to storage, and another part provided power supply for circuit chips. Characteristic of the selected chip is low power and high stability. Analyzing the energy harvester’s structure and principles, a basic electronic circuit for storing the electrical energy is also introducing. The amount of output electrical energy about energy harvester is controlled by magnetic field strength, amplitude and frequency of human movement.

Energy harvesting methods that use functional materials have attracted interest because they can take advantage of an abundant but underutilized energy source. Most vibration energy harvester designs operate most effectively around their resonant frequency. However, in practice, the frequency band for ambient vibrational energy is typically broad. The development of technologies for broadband energy harvesting is therefore desirable. The authors previously proposed an energy harvester, called a flexible piezoelectric device (FPED), that consists of a piezoelectric film (polyvinylidene difluoride) and a soft material, such as silicon rubber or polyethylene terephthalate. The authors also proposed a system based on FPEDs for broadband energy harvesting. The system consisted of cantilevered FPEDs, with each FPED connected via a spring. Simply supported FPEDs also have potential for broadband energy harvesting, and here, a theoretical evaluation method is proposed for such a system. Experiments are conducted to validate the derived model.
