The principle essentially revolves around the conversion and retention of energy in a rotational form, allowing for effective management of surplus power and its release when needed.
A cylindrical triboelectric nanogenerator enabled by coupling swing-rotation switching mechanism (SR-TENG) with potential energy storage/release strategy is proposed to harvest irregular, low-frequency, and low-intensity mechanical energy.
A FESS is a mechanical energy storage system for energy storage in kinetic form through the rotation of a large rotating mass with high inertia, i.e., the flywheel (Faraji et al., 2017).

Herein, we have developed a high-performance triboelectric nanogenerator (SD-TENG) with low friction, high durability, swing-induced counter-rotating motion mechanism (SICRMM) and dual potential energy storage and release strategy (DPESRS).
Recently, rotation-based methods have emerged to provide new routes for the heat transfer enhancement of LTES systems, and many achievements have been obtained by researchers around the world.
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.
Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly
The locking assembly provides a triggered release mechanism for selective release of stored energy from the torsion spring that accordingly rotates the lever member.
Is there a mechanical mechanism that stores energy by rotating force and releases energy by rotating force? It doesn''t have to be spring operated, but I think it''s the only way to work, with springs.
