“…In this structure, there are energy harvesting rings on the wrist and ankle, which include the magnetic ball that rolls in the rings, and the coil is cut to generate electricity, as shown in Figure 3a. Under an excitation vibration of 5 Hz, the energy harvester can provide an average power of 8.8 mW under the optimal load resistance of 104.7 Ω. Zhou et al 73 proposed a Halbach array-enhanced electromagnetic energy harvester with a pendulum to maximize the use of limb swing excitation, as shown in Figure 3b. The theoretical model of the magnetic array was established using the magnetic charge method.…”

In the Internet of Things era, wearable electronics and sensors have become essential for health monitoring and human computer interaction. However, a continuous power supply is an urgent demand in the field of distributed sensing. Energy harvesting from daily human activities and its conversion into electricity are expected to replace traditional batteries and wearable power supplying electronic devices. This article reviews the electromagnetic, piezoelectric, and triboelectric energy harvesting technologies from human motions, including joint rotation, limb swing, force application, fold stretching, and organ motion. It also discusses and analyzes the advantages and disadvantages of various recently proposed human energy harvesters. In addition, possible applications of active sensing and wearable powered electronic devices driven by human body kinetic energy harvesting are provided. Finally, the concept of a human energy and information exchange center based on energy harvesting is proposed as a future prospect.

“…It has been noticed that EM waves have adverse effects on human health, [10][11][12] so scavenging waste EM energy could be beneficial. [13][14][15][16][17][18][19][20][21] In this connection, Zhang et al have fabricated a double-ring core-based EM energy harvester to scavenge waste energy around power lines. It is capable of obtaining the output power of 32.78 mW at the transmission of a 10 A current across power lines.…”

Harvesting energy from waste resources shows significant potential in low‐power electronics, self‐powered devices, and waste‐energy management. Herein, a possible mechanism is demonstrated to harvest waste electromagnetic (EM) energy produced by the induction heater where recycled aluminum foil is utilized as an energy‐harvester unit. As a consequence, ≈5.34 μW of harvested power is manifested under the operating condition of the induction heater. In this connection, a demonstration of the real‐time calculator operation, 26 blue light‐emitting diode lighting, and smartphone battery charging are presented. It indicates an excellent opportunity to harvest the abundantly available waste EM energy using the recycled and widely used food‐packaging Al foil. Thus, it is expected that the waste EM energy can be utilized to power up consumer electronic appliances.

“…In this short paper we would like to focus on a few application of the Vibration EH systems studied in laboratories of Lublin University of Technology (Poland) and University College Dublin (Republic of Ireland), from the point of view of young researchers. In the following sections we would like to demonstrate the aforementioned − concepts with the help of two electromagnetic EH systems namely the pendulum [7,8] and the piezoelectric EH systems [9,10]. The novelty of presented pendulum-based concepts refers to the impact influence [11,12] on the pendulum's dynamics and study of dynamically changing magnetic interference [13,14] between fixed and moving magnet on the pendulum.…”

Energy Harvesting is the process in which energy is captured from a system's environment and converted into usable electric power. Energy harvesting allows electronics to operate where there's no conventional power source, eliminating the need to run wires or make frequent visits to replace batteries, that makes it the new possibility of green energy source. This short letter reports the 3 new designed energy harvesting systems based on the electromagnetic and piezoelectric effect from two universities, i.e. Lublin University of Technology (Poland) and University College Dublin (Republic of Ireland). The proposed systems can be used as a power supply for low-energy devices or in the diagnostics.
