Coupled plate energy models at mid-and high-frequency vibrations. PEREIRA V S,DOS SANTOS J M C. Computers and Structures . 2014Pereira V S, Dos Santos J M C. Coupled plate energy models at mid- and high-frequency vibrations[J]. Computers & Structures, 2014, 134(4): 48-61....
Energy from low frequency vibrations is absorbed by a low frequency bounded resonator and subsequently pumped, in the form of pulses, to a high frequency resonator. The mechanical energy of the high frequency resonator is then transferred to the electrical domain by electromagnetic induction. The ...
In the energy-harvesting field, one of the key issues is how to realize efficient energy extraction from ultra-low frequency excitation sources. To offer a solution to this issue, this paper presents a monostable electromagnetic energy harvester (EMEH) that is composed of a magnet-spring resonator...
1.2 A.2 Counter-propagating waves with equal amplitude and frequency It can be misleading, from our point of view, to use the word “standing” for waves propagating in opposite directions because waves are never stationary. Names are sometimes at the inception of misconceptions. If counter-propa...
Unfortunately, in the vast majority of practical scenarios, ambient vibrations are frequency-varying or totally random with energy distributed over a wide frequency range. Hence, increasing the bandwidth of vibration energy harvesters has become one of the most critical issues before these harvesters ...

induction, in the past 5 years, triboelectric nanogenerator (TENG) has been applied as a fundamentally new technology to revive the field of vibration energy harvesting and self-powered sensing, especially for low-frequency vibrations such as human motion, automobile, machine, and bridge vibrations....
A parametric coupling device (abbreviated as PCD), capable of both temperature sensing and energy harvesting, is proposed with a common wings-inspired structure. Under one low frequency vibration excitation, the vibration energy can be potentially converted to electric energy, while the output ...
