Harvesting energy from the motion of human limbs: the design and analysis of an impact-based piezoelectric generator

Abstract

In the first line of table 1, the formula for m (kg) should be: 33 140 ρW(t s + 2t p )l 3 + m t in place of 33 140 ρW(t s + 2t p )l 3 + m t l 3 . In equation (2), the symbol m is in one spot placed in a subscript position when it should not be. The corrected formula is v M0 = mv b0 +Mv M0 + em(v b0 −v M0 ) M+m in place of v M0 = mv b0 +Mv M0 + e m (v b0 −v M0 ) M+m.

Realistic Circuit Model of an Impact-Based Piezoelectric Energy Harvester

“…The basic difference between them is the number of degrees of freedom [12]. The distributed-parameter system is usually limited to a specific situation: steady state at harmonic excitation [1,12,13]. The targeted impact-based harvester generates signals at different frequencies other than a driven frequency.…”

“…Recently, energy harvesters to convert mechanical energy into electrical energy have been studied as a power source for small and low power electronic devices such as wireless sensing nodes and implantable medical devices [1,2]. Most vibration-based harvesters have been implemented using electrostatic, electromagnetic and piezoelectric transduction mechanisms.…”

“…Therefore various harvesters, which can work at low frequency random vibrations, have been researched to improve energy conversion efficiency [1,2].…”

A non-resonant, frequency up-converted electromagnetic energy harvester from human-body-induced vibration for hand-held smart system applications

“…[2][3][4][5] Basic human activities (e.g., walking, running, shaking limbs, jumping, etc.) produce mechanical vibrations that can be converted to useful electrical energy by various transaction mechanisms such as electromagnetic, 5 piezoelectric, 6 and electrostatic 7 mechanisms. A suitable human-body-induced vibration energy harvester can be used to power various consumer electronics, e.g., mobile phones, wrist watches, audio devices, hearing aids, implanted biomedical devices, etc.…”

Energy Harvesting from Air Conditioning Condensers with the Use of Piezoelectric Devices

“…The best-known applications of piezoelectric crystals are: sensing elements, ultrasound imaging, sonar sensors, chemical and biological sensors, music instruments, automotive applications, piezo-resistive silicon devices, etc. [10][11][12][13].…”
