Mechanical springs are elastic devices that store mechanical potential energy when deformed through compression, tension, or torsion. Hooke''s Law: Understanding the Principle of Springs. Hooke''s Law describes the force needed to compress or extend a spring: F=−kXF = -kX F = − k X. F: Force exerted by the load on the spring; X: Spring displacement; k:
The energy that is lost during braking is stored in a spring by virtue of torsion force. Energy storing and releasing operations are done gradually and uniformly by the use of the combination of internal gears and spur gears.

Torsion springs release their stored energy through twisting or rotation. The force required for a torsion spring to twist depends on its rate and how much rotation occurs. When a torsion spring twists or rotates, it stores potential energy in deformation strain, which causes it to return to position once released. Factors That Affect Energy

The concept of using a torsion spring as a means of mechanical energy storage before the energy conversion to electricity has the substantial benefit of being able to directly capture and accumulate all input motion, even in the event of sudden impacts, and then convert this mechanical energy through a motor to provide a smoothed electrical output.
Finally, the torsion spring mechanism was shown through simulation to drastically reduce the torque transmitted by vital mechanical components, particularly at start-up, thus minimising the likelihood of damage to the transducer during operation and improving the overall durability and longevity of the device.
