Therefore, this article describes a wearable human lower limb energy harvesting and transmission exoskeleton (EHTE) to achieve biomechanical energy during walking; to achieve the energy harvest, management, and migration. The EHTE is mounted on the thigh and the flat spiral springs are used to create the energy from leg swings.
To fully utilize all limb movements of humans, a high-power biomechanical energy harvester that employs a hybrid synergistic drive mechanism (HBEH-HSDM) is proposed. The synergistic employment of various forms of human motion excitation allows the harvester to work more effectively, and improve the output power quality.
However, the highest energy storage possible for Li-ion batteries is insufficient for the long-term needs of society, for example, extended-range electric vehicles. To go beyond the horizon of Li-ion batteries is a formidable challenge; there are few options. Here we consider two: Li–air (O2) and Li–S.
The resulting individual LIMB delivers ultrahigh areal capacity of 1431 μAh cm -2, ultralong cyclability without obvious capacity loss after 8000 cycles, and excellent dimensional customizability.
Besides, advanced electrode microfabrication techniques such as screen printing [29, 30], inkjet printing, and 3D printing have been developed to optimize the production efficiency and cost of flexible LIMBs [, , ].
Attributing to the flexibility of all components, especially solid-state electrolyte, together its strong interfaces with cathode and anode, our solid-state LIMBs demonstrate exceptional mechanical flexibility, without performance degradation after repeated bending.
