“…Integrated circuits based on the SECE concept have been investigated for microwatt power [105] and low-voltage [106] applications. The power conversion efficiency is limited in these applications; the reported efficiency of the rectifier-free topology of [106] is 40% at an input voltage of ±0.75 V and efficiency of the synchronous boost-converter-based design [105] reaches 50% at 2.2 μW input.…”

In this paper, a summary of published techniques for power conditioning within energy harvesting systems is presented. The focus is on low-power systems, e.g, <10 mW, for kinetic energy harvesting. Published concepts are grouped according to functionality and results contrasted. The various techniques described are considered in terms of complexity, efficiency, quiescent power consumption, startup behavior, and utilization of the harvester compared to an optimum load. This paper concludes with an overview of power management techniques that aim to maximize the extracted power and the utilization of the energy harvester.

“…Compared with the existing results [29,[53][54][55], the amounts of energy harvested, expressed as a peak-to-peak voltage for all samples (Table 2), indicate good values ranging between 25 and 140 V. As films of different thicknesses were measured, the peak-to-peak voltages have been reported for the film thicknesses in order to have better comparison of the samples to each other. It seems, Fig.…”

A strategy, consisting in the use in tandem of two active fillers in different ratios with complementary effects: silica mainly as a reinforcing agent and barium titanate as dielectric permittivity enhancer, was proposed to optimize the electromechanical properties of the silicone elastomers. A high molecular mass polydimethylsiloxane-a,x-diol (M w = 642000 g mol -1 ) was used as a matrix to prepare silicone composites which further were processed as films and crosslinked at high temperature. The morphological, thermal, and moisture behaviors of the films were studied by adequate techniques. The mechanical properties were estimated on the basis of normal and cyclic stress-strain curves. Dielectric spectra were recorded in the frequency range of 1-10 6 Hz at normal temperature. The voltages generated by a mechanical impulses created by falling of a metal ball of 7.1 g from a height of one hundred millimeters on the surface of the films placed between two electrodes ranged between 28.4 and 157.3 V mm -1 .

“…18). 90 The suggested circuit was a simple and scalable, which could reach 71% of high conversion efficiency. Very recently, for ultralow input piezoelectric voltage, Peters et al 91 suggested two stage concept including passive stage and only one active diode, resulting in successful rectification of tens of mV with very high efficiency over 90% (Fig.…”

This paper reviews energy harvesting technology from mechanical vibration. Recent advances on ultralow power portable electronic devices and wireless sensor network require limitless battery life for better performance. People searched for permanent portable power sources for advanced electronic devices. Energy is everywhere around us and the most important part in energy harvesting is energy transducer. Piezoelectric materials have high energy conversion ability from mechanical vibration. A great amount of researches have been conducted to develop simple and efficient energy harvesting devices from vibration by using piezoelectric materials. Representative piezoelectric materials can be categorized into piezoceramics and piezopolymers. This paper reviews key ideas and performances of the reported piezoelectric energy harvesting from vibration. Various types of vibration devices, piezoelectric materials and mathematical modeling of vibrational energy harvestings are reviewed.
