“…There are in the academic literature some recent works concerning the BLE nodes for WSN powered by the ambient energy harvesting or WPT. Some harvest ambient light [12,13], mechanical vibrations [13,14], temperature gradient [15], electromagnetic inductive field [16], electromagnetic radiative waves [17], or multiple sources [13], while others are based on the radiative electromagnetic WPT [18,19], but all power a BLE node, battery-free [12,[14][15][16][17][18][19] or not [13,16], and with [12][13][14][16][17][18][19] or without sensor [15]. Those based on ambient energy harvesting are highly dependent of their environment and of their application, while those based on the WPT have limited range of use in the air (tested up to 2 m), are based on a "direct consumption" strategy, and their periodicity of data measurement and transmission is configured by software.…”

This paper presents a Bluetooth Low Energy sensing node, part of a wireless sensor network dedicated to the deployment of a cyber-physical system for the structural health monitoring of reinforced concretes throughout their life. This fully wireless sensing node is designed to measure temperature and relative humidity, and wirelessly transmit the collected data in its network, as well as to be energy autonomous. For that, it is battery-free, able to cold-start, and wirelessly and remotely powered -and controlledover several meters by communicating nodes (other part of the network, assuring the connection to the digital world) via a radiative electromagnetic power transfer system.

Encapsulation of magnetostrictive alloy wires in epoxy resin has great potential for energy harvesting and can be applied to energy harvesting in human motion. In this work, a magnetostrictive wire-epoxy resin arch composite structure was proposed for harvesting energy generated by foot motion. A prestress was introduced during the resin curing process, and the relationship between the output voltage and material properties was derived based on the Villari effect. Three kinds of Fe-based magnetostrictive wires were prepared and their magnetic properties were measured, then a prototype single-layer arch composite structure was fabricated and an experimental platform was built for testing, and the amplitude of the output open-circuit voltage could reach 936 mV under an impact pressure of 750 N, which proved that the Fe–Ga alloy composite structure was superior to Fe–Co and Fe–Ni alloys in energy harvesting. The double-layer arch-shaped Fe–Ga composite structures energy harvesting prototype outputs a maximum voltage of up to 940 mV in foot energy harvesting experiments, and collected a maximum power of up to 2.45 mW at a step frequency of 3.5 Hz. Consequently, this work emphasized the feasibility of magnetostrictive alloy-epoxy composite structures for energy harvesting in human motion and the potential for developing new ways of energy harvesting.

“…Hybrid cell architecture has been proposed in literature that can generate electricity everywhere and anytime, using multiple sources of energy that enhances the harvester performance due to synergetic effects . A unified power management circuit for a hybrid ambient light and vibration harvester has been demonstrated, , and several improvements have been proposed. , However, the power output from these prior harvesters still remains low and limits their usage in practical applications.…”

The energy available in the ambient vibrations, magnetic fields, and sunlight can be simultaneously or independently harvested using universal architecture. The universal harvester design is shown to effectively convert ambient magnetic fields, vibration, and light into electricity. The architecture is composed of a perovskite solar cell integrated onto a magnetoelectric composite cantilever beam. The efficiency of the large-area perovskite solar cell is shown to reach 15.74% (cell area is >1100% larger than traditional perovskite solar cells) by selecting glass/indium tin oxide (ITO) as the cathode that reduces the charge recombination. The magnetoelectric composite beam is designed to include the effect of the mass and volume of the solar cell on power generation. Results demonstrate that universal energy harvester can simultaneously capture vibration, magnetic fields, and solar irradiation to provide an ultrahigh-power density of 18.6 mW/cm 3 . The total power generated by the multienergy harvester, including vibration, magnetic field, and solar stimuli, is 23.52 mW from a total surface area of 9.6 cm 2 and a total volume of 1.26 cm 3 . These results will have a tremendous impact on the design of the power sources for Internet of Things sensors and wireless devices.
