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...

Recent progresses in microelectronics that enabled the design ultra-low consumption, fully operative electronic systems, have permitted the disposal of autonomous wireless devices ([1]). However, primary batteries, that initially promoted the development of such systems, have nowadays become a break to the spreading of long-lifetime autonomous apparatus, mainly because of their limited lifespan...

Vibration energy capture devices can convert the mechanical from ambient source into electrical energy. The captured provide for low-power such as microelectromechanical systems(MEMS) a supplement to power system. has been widely concerned by researchers because of characteristics easy access and green. conversion vibration be achieved electromagnetic, electrostatic, piezoelectric, magnetostric...

This paper presents the design, fabrication and characterization of an electromagnetic MEMS energy harvester with ultra-broad operating bandwidth. The beam stretching induced nonlinear spring stiffness enables the resonance to extend from 65 Hz to 340 Hz and 400 Hz at accelerations of 0.5g and 1.0g, respectively. The ultra-wide bandwidth could benefit the harvester device for more efficient vib...

This paper reviews the state-of-the art in vibration energy harvesting for wireless, self-powered microsystems. Vibration-powered generators are typically, although not exclusively, inertial spring and mass systems. The characteristic equations for inertial-based generators are presented, along with the specific damping equations that relate to the three main transduction mechanisms employed to...

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...
