What are the transduction mechanisms of vibration energy harvesting?

Transduction mechanisms of vibration energy harvesting essentially rely on the electromagnetic , , , , electrostatic , piezoelectric , , , and triboelectric phenomena , , , .

Which mechanism is used for transmission of vibration-to-rotation?

The rack and pinion mechanism for transmission of vibration-to-rotation is widely used in backpack [2, 4], road [, , ] and vehicle suspension [8, 9] vibration energy harvesting. The relative motion of the backpack and shoulder is a kind of available vibration energy.

What is vibrational energy transfer?

This energy transfer is essentially a process of energy redistribution. The vibrational energy that would otherwise flow to the protected object, potentially causing serious harm, is largely transferred to the power-generation unit, thus making the vibrational energy be utilized more efficiently.

Why are vibrational energy harvesting technologies based on vibration-increasing and vibration-attenuation difficult?

The contradiction between the vibration-increasing and vibration-attenuation processes makes vibrational energy harvesting technologies based on vibration enhancement difficult to apply in many scenarios where vibrations must be mitigated.

What is vibrational energy harvesting & vibration attenuation?

This approach unifies vibrational energy harvesting and vibration attenuation. It overcomes the contradiction between vibration enhancement and vibration reduction. Energy redistribution enables 95.8% of the energy to flow to power-generation unit. TENG and vibration control realize interdisciplinary integration for the first time.

Can a coil switching self-adaptation system improve energy conversion from mechanical vibrations?

Up to 14-fold larger output average power and 5.5-fold larger electric efficiency demonstrate the potential of the proposed coil switching self-adaptation system for enhancing the total energy conversion from general widespread mechanical vibrations. 1. Introduction
