Amidst the swift progression of microelectronics and Internet of Things technology, wearable devices are gradually gaining ground in the domains of human health monitoring. Recently, human bioenergy harvesting has emerged as a plausible alternative to batteries. This paper delves into harvesting human inertial energy that stimulates inertial masses through human motion and then transmutes the motion of the inertial masses into electrical energy. The inertial energy harvester is better suited for low‐frequency and irregular human motion. This review first identifies the sources of human motion excitation that are compatible with inertial energy harvesters and then provides a summary of the operating principles and the comparisons of the commonly used energy conversion mechanisms, including electromagnetic, piezoelectric, and triboelectric transducers. The review thoroughly summarizes the latest advancements in human inertial energy‐harvesting technology that are categorized and grouped based on their excitation sources and mechanical modulation methods. In addition, the review outlines the applications of inertial energy harvesters in powering wearable devices, medical health monitoring, and as mobile power sources. Finally, the challenges faced by inertial energy‐harvesting technologies are discussed, and the review provides a perspective on the potential developments in the field.

“…This design cleverly exploits the contrasting forces between the wearer and the backpack to generate electric energy, resulting in a recovered energy of approximately 50 mW. Mostafavi et al [19] presented the design and modelling of an energy-harvesting backpack that utilizes a mass-spring-damping oscillating system and a mechanical motion rectifier unit. The prototype designed for normal walking speed exhibited an average power of 4.37 W. Huang [20] discussed the power generation performance and efficiency of two types of harvesters installed in backpacks during human walking, suggesting the potential to generate electrical power of 6 W without increasing metabolic costs.…”

Energy harvesting from human body kinetics is a crucial issue. The primary challenge lies in designing and optimizing the energy converter. This paper presents an analysis of energy harvesting using three variants of electromagnetic harvesters designed for backpack integration. The first harvester comprises a single levitating magnet within a coil. The second concept involves a specially designed oscillating magnet consisting of two divided magnets with a separator. The third harvester variant utilizes two levitating magnets within the coil. The results indicate that, for harmonic excitation, the harvested power is the highest for the classical harvester with a single oscillating magnet. However, when integrated into a backpack, the concept of two levitating magnets proves to be more effective in lower speed ranges.
