Energy harvesting is a powerful technique to produce clean and renewable energy with better infrastructure improvement. The exhaustive review of recent progress and development in bio-mechanical energy harvesting (BMEH) techniques from human body is discussed in this manuscript. The BMEH from the human body is categorized into three parts, namely, piezoelectric energy harvesting (PEEH), triboelectric energy harvesting (TEEH), and Electro-magnetic Energy harvesting (EMEH). Each energy harvesting system is discussed with working principles with mathematical equations; each energy harvesting progress is discussed with a few work demonstrations. The applications of each energy harvesting from the recent research work are addressed in detail. The summary of each energy harvester from the human body or motion with advantages, limitations, performance metrics, current methods, and implemented human body parts are highlighted with Tabulation. The critical challenges/issues with possible solutions are also discussed.

“…Motion from the human body [ 5 ], animals [ 6 ], or mechanical equipment [ 7 ] can be used to charge batteries [ 8 , 9 ] or power objects, such as wearable devices [ 10 , 11 ], tactile sensors [ 12 , 13 ], and biomedical devices [ 14 , 15 ]. This motion can be generated by rotational [ 16 , 17 , 18 , 19 ], linear [ 20 , 21 ], vibrational [ 22 , 23 , 24 ], or forced fluid induction [ 25 , 26 , 27 , 28 ] systems.…”

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.

“…Abdelnaby and Arafa [8] proposed an electromagnetic EH capable of generating 0.14 mW from 5 Hz excitation frequency and 1.8 mm excitation amplitude. Other critical influences in energy harvesting using electromagnetic transductions include applications of cantilever beams [8][9][10], rotational mechanisms [11][12][13][14] and pendulum-based structures [15][16][17].…”

Wireless sensors face challenges regarding power supply and maintenance when batteries are used. To provide an effective solution, this paper presents a bistable energy harvester capable of exploiting ultra-low frequency vibration to energize low-powered devices. The energy harvester uses rotary-translational motion of a spherical rolling magnet contained inside a frame, with two tethering magnets below the rolling magnet's path to enable two stable positions. To examine the performance of the design, a prototype was fabricated and tested under varying excitation conditions and external loads. An output of 7.1 mW at 750 Ω was effectively determined. A power management circuit is integrated with the energy harvester; the harvester can charge a 470 µF capacitor to 3.4 V within 82 s at 0.7 g and 2 Hz.
