The Study and Development of Energy Harvesting Vibration Absorbers
Vibrational energy harvesting seeks to convert ambient energy into electricity when battery replacement or line transmission is infeasible or impracticable. Electromechanical mass-spring harvesters are designed to exhibit a resonance frequency close to the principal vibrational frequency of the main or environmental system; excited near to resonance, the harvesters convert the kinetic or potent...
متن کاملElectromagnetic energy harvesting from flow induced vibration
A new electromagnetic energy harvester for harnessing energy from flow induced vibration is developed. It converts flow energy into electrical energy by fluid flow and electromagnetic induction. A finite element model for estimation of the generated voltage of the energy harvester is developed. A prototype of the energy harvester is fabricated and tested. Experimental results show that an outpu...
متن کاملOn energy harvesting from ambient vibration
Future MEMS devices will harvest energy from their environment. One can envisage an autonomous condition monitoring vibration sensor being powered by that same vibration, and transmitting data over a wireless link; inaccessible or hostile environments are obvious areas of application. The base excitation of an elastically mounted magnetic seismic mass moving past a coil, considered previously b...
متن کاملFundamental issues in nonlinear wideband-vibration energy harvesting.
Mechanically nonlinear energy harvesters driven by broadband vibrations modeled as white noise are investigated. We derive an upper bound on output power versus load resistance and show that, subject to mild restrictions that we make precise, the upper-bound performance can be obtained by a linear harvester with appropriate stiffness. Despite this, nonlinear harvesters can have implementation-r...
متن کاملVibration Energy Harvesting: Linear and Nonlinear Oscillator Approaches
An important question that must be addressed by any energy harvesting technology is related to the type of energy available (Paradiso et al., 2005; Roundy et al., 2003). Among the renewable energy sources, kinetic energy is undoubtedly the most widely studied for applications to the micro-energy generation1. Kinetic energy harvesting requires a transduction mechanism to generate electrical ener...
