The sound waves create vibrations on the diaphragm, and the spring converts those vibrations into an electrical current. This current is then fed into a power generator and transferred into energy.
Wang and Chang [119] developed a new vibration energy harvesting device based on the vibration induced by liquid flow in channels. The structure is illustrated in Fig. 19 , in which the permanent magnet is surrounded by a fixed coil and attached to the polyester diaphragm.

Based on the generic spring-mass-damper model of vibration-based energy harvesting discussed in Section 2, in order to maximize the use of the energy harvesters for a particular application, the structure frequency of the energy harvesting device is designed to match the source frequency (ฯ struc = ฯ s). Due to the fact that the vibration
Learn more about vibration energy harvesting as a source of power for electronic systems. Each energy harvesting technology has its pros and cons and energy vibration energy harvesting is no exception.. One of the advantages is that vibrations are almost everywhere: on a car, on a train, on an airplane, on a bike, on a washing machine, on the rotor of a wind generator, on a bridge, on skis, on

Moreover, the presence of the van der Pol model with the RLC circuit can significantly reduce the critical wind speed required to harvest energy. This result may provide an optimization process that can be used to supply some guidelines in the design of galloping vibrations-based electromagnetic energy harvesters. In this study, a hybrid piezo-electromagnetic with triple piezoelectric energy harvester (TPEH) was created for vibration energy harvesting from roadside vibration, which consists of spring as a key component to increase energy harvesting efficiency (Fig. 7 (a)). Based on the experimental results, it can be concluded that at K = 20 N/kg, the This paper proposes an improved electromagnetic damper cum energy harvester (EMDEH), consisting of an electromagnetic damper and a specially designed energy harvesting circuit (EHC). EMDEH is intended to suppress structural vibrations by harvesting vibration energy of structures. A microcontroller unit (MCU) is applied in the EHC to control the power switch by adjusting the duty cycle
