Abstract In this thesis, the design of a self-tunable energy harvester based on pendulum oscillation low-frequency vibration energy from horizontal excitations. The device is equipped with mechanical motion rectifier MMR to improve the output power. The frequency adjustment of the system has been demonstrated experimentally by changing the length of the pendulum rod automatically through a complete control circuit to achieve a state of resonance |
