A novel multi-source energy harvester based on solar and radioisotope energy sources is designed and simulated in this work. We established the calculation formulas for the short-circuit current and open-circuit voltage, and then studied and analyzed the optimization thickness of the semiconductor, doping concentration, and junction depth with simulation of the transport process of β particles ...

A new class of vibrational energy harvester based on Magnetostrictive material (MsM) Metglas 2605SC is deigned, developed, and tested in building practical energy harvesting wireless sensor networks. Compared to piezoelectric material, Metglas 2605SC offers advantages including ultra-high energy conversion efficiency, high power density, longer life cycles without depolarization issue, and flex...

A novel piezoelectric energy harvester equipped with two piezoelectric beams and two cylinders was proposed in this work. The energy harvester can convert the kinetic energy of water into electrical energy by means of vortex-induced vibration (VIV) and wake-induced vibration (WIV). The effects of load resistance, water velocity and cylinder diameter on the performance of the harvester were inve...

In this paper, a Micro – Electrical Mechanical System (MEMS) energy harvester is developed, using the phenomenon of Piezoelectricity. Zinc Oxide (ZnO) was chosen as the piezoelectric material. A multi – d31 mode cantilever design was used with varying dimensions of cantilever, to form an array. The individual cantilevers can be either connected in series or parallel to achieve different output ...

Abstract — With the rapid expansion of portable consumer and industrial devices, there is a present need for small, wireless, and portable power sources. Aside of traditionally used batteries, energy harvesting is one of the options that seems particularly attractive and cost efficient. This paper presents a novel method of retrieving energy from an electromagnetic field surrounding a current-c...

Magnetic plucking applies the strategy of frequency up-conversion in inertial energy harvesting when the energy source, such as human motion, only provides excitations with very low and irregular frequencies. This paper presents an analysis of three different magnet configurations to achieve magnetic plucking based on a three-dimensional analytical cube permanent magnet model: direct repulsive ...

In this paper, we propose an active control method to adjust the resonance frequency of a capacitive energy harvester. To end, harvester is tuned using electrostatic force, which actively controlled by voltage source. The spring softening effect force used accommodate dominant ambient mechanical vibration within bandwidth region. A single degree freedom considered, and nonlinear equation motion...
