Traditional small-scale vibration energy harvesters have typically low efficiency of energy harvesting from low frequency vibrations. Several recent studies have indicated that introduction of nonlinearity can significantly improve the efficiency of such systems. Motivated by these observations we have studied the nonlinear electrostatic energy harvester using a combination of analytical and nu...

Department of Biosystems Engineering, University of Kurdistan, Sanandaj, Iran Received: November 2nd, 2014; Revised: November 19th, 2014; Accepted: January 28th, 2015 Purpose: Slow manual harvesting of rain-fed chickpeas cultivated in fallow fields in developing countries have encouraged the design of a mechanical harvester. Methods: A tractor-pulled harvester was built, in which a modified str...

The use of inorganic-based flexible piezoelectric thin films for biomedical applications has been actively reported due to their advantages of highly piezoelectric, pliable, slim, lightweight, and biocompatible properties. The piezoelectric thin films on plastic substrates can convert ambient mechanical energy into electric signals, even responding to tiny movements on corrugated surfaces of in...

With the development of low power electronics and energy harvesting technology, selfpowered systems have become a research hotspot over the last decade. The main advantage of self-powered systems is that they require minimum maintenance which makes them to be deployed in large scale or previously inaccessible locations. Therefore, the target of energy harvesting is to power autonomous ‘fit and ...

Since the advent of modern civilization, humans have always been depended upon fossil fuels as source energy for their daily requirements. With exponential growth in population, dependence on these conventional sources requirements has led to depletion same and adverse ill-effects environment. To lessen burden if possible, minimize zero, harvesting become need hour development different technol...

Energy harvester is a self-generating energy source which is able to run small scale electronic devices. It largely reduces the dependency on external power source. This paper represents the utilization of micro cantilever beam to develop a vibration based electromechanical systems (MEMS) piezoelectric energy harvester system. The proposed micro cantilever part has been developed by finite elem...
