An electromagnetic energy harvester with a half-wave rectification mechanism for military personnel

Harvesting Inertial Energy and Powering Wearable Devices: A Review

“…As can be seen from the table, eccentric proof mass, energy conversion mechanism, and excitation frequency will affect the output performance of the system. [140][141][142] In Figure 12. Optimized design of eccentric rotor harvester.…”

“…As can be seen from the table, eccentric proof mass, energy conversion mechanism, and excitation frequency will affect the output performance of the system. [ 140–142 ] In addition, the analysis of this type of energy harvester shows that the eccentric proof mass has a significant performance improvement in continuous rotation compared to the oscillating state, so it is important to explore the conditions under which the proof mass changes from oscillating to continuous rotation. On the other hand, the response of the system to human excitation can be enhanced by improving the structural design, such as torsion spring, magnetic spring, frequency conversion mechanism, bidirectional one‐way design, and so on.…”

UV-modification of Ag nanoparticles on α-MoCx for interface polarization engineering in electromagnetic wave absorption

“…In modern society, especially in the 5G era, electronic installations are widely applied in people's daily lives, 1 as well as medical, 2 military, 3 industry, 4 and other fields. [4][5][6] Electromagnetic wave (EW) pollution poses a serious threat to human health and has attracted attention.…”

A self-powered and self-sensing knee negative energy harvester

“… 4 However, for workers who are on the go for long periods, batteries with limited capacity need to be replaced or recharged frequently, which hinders the convenience of wearable devices. 5 Self-powered technology based on energy harvesting is a promising solution to the endurance problem of wearable devices. 6 , 7 , 8 , 9 …”
