Design of magnetic field alarm  powered by magnetic energy harvesting

This paper presents a design of magnetic field alarm powered by magnetic energy harvesting. It consists of an energy harvesting module, Cockcroft-walton circuit and piezo buzzer. The energy harvesting module is composed of coil and magnetic flux concentration core. It can generate 200 µW from an environmental magnetic field of 200 µT at 60 Hz. The Cockcroft-walton circuit can converts the ac voltage to a suitable dc voltage for the piezo buzzer.  This alarm can notice not only

Energy harvested end nodes and performance improvement of LoRa networks

or using energy harvesting for LoRa nodes, will result in the development of sustainable and strong IoT in future. The related work presented in the next section, reviews work that has already been reported in the literature. The main contributions of this paper are as follows: The resource allocation used maximizes the LoRa user rates, and the LoRa users harvest energy from external sources. The total time taken, including harvesting, transmission, and reception time at the gateway, is used

Optimisation  of solar power intake for wireless sensor networks at temperate latitudes

In many outdoor locations solar power provides the greatest power densities for energy harvesting to power wireless sensor networks in comparison to other practical alternative such as wind, vibrations or temperature gradients. Since solar power is highly variable with location and time, it is necessary to optimise the sensor nodes for individual locations.  Presented here, is an assessment of the solar power availability in Manchester, UK (53°28′N, 2°14′W). Wireless

HYBRID POWER HARVESTER USING ENGINE SOURCE

In mainly we present a compact, multisource and battery-free energy harvesting from engine source. This battery free generator captures energy from its environment transient thermal gradients as a main source, and vibration as a secondary source allowing early biasing of the generator and stores this energy in ultra-capacitors .In this way, this multi-source architecture benefits from the synergy between energy scavenging and harvesting.

A COMPREHENSIVE ANALYSIS ON SIZING OF SOLAR ENERGY HARVESTER ELEMENTS FOR WIRELESS SENSOR MOTES

Wireless sensor networks (WSN) have limited lifetime due to on board battery. The lifetime can be improved by energy harvesting solutions. In this paper the solar energy harvester requirements for TelosB mote has been analyzed and calculated. Photovoltaic (PV) panel and battery sizing requirements are calculated by assuming that the mote follows SMAC and TDMA-MAC schedule for image communication. The calculations are validated by comparing it with the parameters calculated from the real time
