Cutting tool vibration energy harvesting for wireless sensors applications

Energy harvesting vibration sources for microsystems applications

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...

Vibration energy harvesting: fabrication, miniaturisation and applications

This paper reviews work at the University of Southampton and its spin-out company Perpetuum towards the use of vibration energy harvesting in real applications. Perpetuum have successfully demonstrated vibration-powered condition monitoring systems for rail and industrial applications. They have pursued applications were volume is not a particular constraint and therefore sufficient power can b...

Analysis of Energy Harvesting for Vibration-Motivated Wireless Sensor Networks

Extracting an electrical energy from various environmental sources, called energy harvesting (or energy scavenging), has been attracting researchers’ attention in energy replenishable networks. In particular, a piezoelectric device based energy harvesting from ambient vibrations is a promising technique for easy of battery energy replenishment in vibration-motivated wireless sensor networks (WS...

Towards an autonomous self-tuning vibration energy harvesting device for wireless sensor network applications

Future deployment of wireless sensor networks will ultimately require a self-sustainable local power source for each sensor, and vibration energy harvesting is a promising approach for such applications. A requirement for efficient vibration energy harvesting is to match the device and source frequencies. While techniques to tune the resonance frequency of an energy harvesting device have recen...
