In order to extract as much energy as possible from ambient vibrations, many vibration-based energy harvesters (VEHs) are designed to resonate at a specific base excitation frequency. Unfortunately, many vibration energy sources are low frequency (0.5 Hz-100 Hz), intermittent, and broadband. Thus, resonant VEHs would not be excited continuously and would require a large mass or size to tune to ...
This article explores the excitation of different vibrational states in a spatially extended dynamical system through theory and experiment. As a prototypical example, we consider a one-dimensional packing of spherical particles (a so-called granular chain) that is subject to harmonic boundary excitation. The combination of the multi-modal nature of the system and the strong coupling between th...
In this letter, the design of coded modulation for simultaneous wireless information and power transfer (SWIPT) block-fading channels is proposed, both power-splitting (PS) time-switching (TS) nonlinear energy harvesting (EH). With PS, although diversity-rate tradeoff not affected, EH requires asymmetric modulations which leads to an (IT) performance penalty. We thus circular quadrature amplitu...
• A new energy harvesting system has been designed QZEH. The areas where the best is possible have identified. method of impulse excitation on solution was proposed. probability with effectivity determined. This paper presents results modelling a nonlinear multi-stable QZEH (quasi-zero harvester) for from vibrating mechanical devices. Detailed tests were carried out model, which consisted beam ...
