Ker and colleagues5, identified the longitudinal arch of the foot as an elastic storage-return mechanism. These authors estimated, by simulating the loads experienced during running in
Elastic energy storage in muscle and tendon is important in at least three contexts (i) metabolic energy savings derived from reduced muscle work, (ii) amplification of muscle
Compared with the traditional chemical battery, elastic energy storage does not automatically release energy due to self-discharge, therefore the energy can be stored for a much longer time and can be repeatedly stored and released.
Thus, elastic energy storage via spiral springs can improve the stability and controllability of power grid for supply and demand, improving the quality of power grid. It realizes energy transfer in time to meet the balance of energy supply and demand. Fig. 2.
Spiral spring is the most common elastic energy storage device in practical applications. Humanity has developed various types of elastic energy storage devices, such as helical springs, disc springs, leaf springs, and spiral springs, of which the spiral spring is the most frequently-used device. Spiral springs are wound from steel strips [19, 20].
Elastic energy storage technology has good prospects for future utilization with the development of new materials and new technology, and with people's requirements for low-cost, effective, pollution-free, and renewable energy sources. 5. Conclusions
It is expected that relatively little elastic energy will be stored in the first 50% of arch compression based on the non-linear nature of the arch compression-elastic energy relationship identified by Ker et al. 5 (see Online Supplementary Material Fig. S4).
Based on energy storage and transfer in space and time, elastic energy storage using spiral spring can realize the balance between energy supply and demand in many applications, such as energy adjustment of power grid. Continuous input–spontaneous output working style.
