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...

A wide-bandwidth, meandering piezoelectric vibration energy harvester is presented for the first time utilizing the sensor node electronics as a distributed inertial mass. The energy harvester achieves an experimental maximum power output of 198 W when excited with a peak acceleration of 0.2 g (where 1 g is 9.8 m/s2) at 35 Hz. The output power remains higher than half of the maximum power (99 W...

Domestic service robots are currently powered by the mains electricity. The growing multiplication of such devices negatively impacts our environment. In this study, we show the feasibility of harvesting energy from natural light in an indoor environment. The design of the harvester is carefully carried out using an experimental characterisation of several solar panels, while the boost converte...

Abstract—Simultaneous Wireless Information and Power Transfer (SWIPT) has attracted significant attention in the communication community. The problem of waveform design for SWIPT has however never been addressed so far. In this paper, a novel SWIPT transceiver architecture is introduced relying on the superposition of multisine and OFDM waveforms at the transmitter and a power-splitter receiver...

Harvesting the electrical energy from their working environment has become a feasible choice of realizing self-powered systems or providing supplementary power sources to the battery. In this paper, a pre-loaded piezoelectric cantilever bimorph (PCB) energy harvester is adopted as the research object, for which a single degree-of-freedom analytical model and finite element modeling have been ca...

The main problematic about electronic systems deployed in the sea for long periods of time, is to find a feasible way to supply them with the necessary amount of power without the necessity of a periodical supervision. Small systems, such as sensors that belong to a net of milliwatts consuming devices extended in a wide area, cannot be wire-fed because of the inconveniences it might create, and...

This paper reports a microfabricated piezoelectric MEMS inertial energy harvester that can scavenge high-frequency mechanical vibrations in all three dimensions with an active inner volume of only 55 mm. The device can generate 0.1 to 10.5 μW from out-of-plane vibrations (365-465 Hz), and 0.1 to 3.2 μW from in-plane vibrations (680-930 Hz) at 0.5 g acceleration input. The reported harvester is ...
