“…[52] also proposed a linear electromagnetic vibration energy harvester with weak magnetic coupling. The power generators in these studies [50][51][52] were complex in structure and had the disadvantage of generating electricity at one or two narrow resonance points because of a one or two-degree of freedom oscillation system. Therefore, we propose a multi-degree of freedom oscillation system broadband power generation mechanism using ferromagnetic powder in this study.…”

The movement of the creature and the almost wave in the ocean is a low vibration of random energy with a frequency range of 0.1-10 Hz. Because of its low frequency, the opinion has been that electrical energy generation from this low-frequency wave motion through the electromagnetic induction method is difficult. In this study, an electrical generator was created by the electromagnetic induction method by putting a small mass of ferromagnetic powder in nonmagnetic fluid. A broadband vibration energy harvesting model was created in which vibrations are broadened through a multi-degree of freedom oscillation system using ferromagnetic powder. To generate electricity from low-frequency vibrations (1 Hz or less), a non-resonant type model was created by adding fluid to the ferromagnetic powder model and the simulation results confirmed using computational fluid dynamics by creating a working energy harvesting device.

“…A similar approach was adopted in [23], where three different algorithms were proposed for efficient node placement in the network. An energy localization technique for weakly coupled oscillators was proposed in [24]. Energy localization was achieved by mistuning the mass of one of the moving magnets, and the results indicate the benefits of the energy localization phenomenon.…”

The Internet-of-things (IoT) has been gradually paving the way for the pervasive connectivity of wireless networks. Due to the ability to connect a number of devices to the Internet, many applications of IoT networks have recently been proposed. Though these applications range from industrial automation to smart homes, healthcare applications are the most critical. Providing reliable connectivity among wearables and other monitoring devices is one of the major tasks of such healthcare networks. The main source of power for such low-powered IoT devices is the batteries, which have a limited lifetime and need to be replaced or recharged periodically. In order to improve their lifecycle, one of the most promising proposals is to harvest energy from the ambient resources in the environment. For this purpose, we designed an energy harvesting protocol that harvests energy from two ambient energy sources, namely radio frequency (RF) at 2.4 GHz and thermal energy. A rectenna is used to harvest RF energy, while the thermoelectric generator (TEG) is employed to harvest human thermal energy. To verify the proposed design, extensive simulations are performed in Green Castalia, which is a framework that is used with the Castalia simulator in OMNeT++. The results show significant improvements in terms of the harvested energy and lifecycle improvement of IoT devices.

“…The harvester consisted of moving magnets held by elastic springs to create repulsive magnetic force and low mechanical damping. This structure functionalized a localization phenomenon and resulted in an improvement in the device performance [ 61 ]. The design and model of an energy harvester utilizing magnetic levitation to generate oscillation was demonstrated.…”

This paper discusses the development of a multi-directional, universal, electromagnetic energy harvester. The device is a ball consisting of two parts: a rigid spherical core with internal tubes, coils and magnets, and a flexible silicone-based shell holding a carrier fluid. The multi-directional aspect of the design comes from the device’s spherical shape. The harvester generates energy when subject to compressive force, by moving fluid through a tube, pushing a permanently magnetized ball through a coil wound around the tube. A combination of 3-D printed PLA plastic and molded silicone was used to produce a prototype. The energy harvester can be utilized in applications where there is an oscillating compression and it is not limited to certain applications due to its universal ball shape. It was tested at five different frequencies between 4–15 Hz on its four different outer sides producing electricity at a range of 17 to 44 mV.
