Some embodiments of the present invention disclose an energy storage system that compresses springs to store energy and a liquid or gas to transfer that energy into and out of the energy storage system. Some embodiments use one of several spring types, such as compression, torsion, extension and/or leaf springs, to store energy.

SPRINGS. When w inding up a coiled watch spring (spiral torsion spring) the energy is stored and slowly released, providing power to the watch mechanism. This is basically the same mechanism that provides power to wind-up radios, timers and some torches. Spring steel is often used to manufacture the spiral torsion spring.
Fast and powerful movements such as the jump of a flea (Bennet-Clark and Lucey, 1967) or the strike of a mantis shrimp smasher (Patek and Caldwell, 2005) are possible because they use elastic energy storage mechanisms, or latch-mediated spring actuation (LaMSA; Longo et al., 2019) this mechanism, a latch resists motion of a limb …

Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential ...

Designers create springs to store and release energy. When designers compress a spring, it stores the energy in the form of potential energy. The spring can release this potential energy when it returns to its original shape. In technical spring design, springs release energy in three main ways: compression, extension, and torsion.
When a spring is compressed, the spring force acts to expand it; conversely, when a spring is extended, the force works to contract it. This restoring force is essential for the spring''s ability to store energy and is a critical concept in the design and analysis of spring-loaded mechanisms.

A major challenge of GBMs is the required complexity to adapt the mechanism to compensate different payload weight. For the spring mechanisms in Fig. 1 (b)–(e), these often require adjustment of the spring attachment point or spring stiffness. Adjusting the attachment point is not convenient because it requires extra work in practice.
1. Helical Springs. The helical spring is made from a wire, usually of circular cross-section, that is bent in the form of a helix. There are two basic types of helical springs: compression spring and tension spring. In helical compression spring, the external force tends to shorten the spring.
The hooks and loops of the tension spring store and absorb energy. An extension spring provides the connected mechanisms with a restoring force through hooks or loops. Tightly coiled extension springs typically sit in the idle position. More stress in the end hook in contrast to the spring body limits the performance of extension springs.
