Vibration Energy Harvesting Devices have the potential to replace batteries in powering remote sensors. However, the bandwidth of such devices is typically very narrow, and thus, only able to generate sufficient power when the excitation frequency is at the natural frequency of the device. This research aims to design. build and test the behavior of a cantilever beam that has the capability to self-tune its natural frequency mechanically. The self-tuning mechanism is designed based on the observation that vibration causes freely supported disc 10 rotate, and the mass distribution of an asymmetrical disc changes with the rotary position of the disc, which in tum changes the natural frequency of the cantilever beam. The self-tuning mechanism is found to increase the bandwidth of the testing apparatus as compared to the bandwidth without self-tuning. An improvement of up to 318% was observed between the measured vibration magnitudes of the self-tuning system vs the system without set-tuning. The vibration magnitude is characterized by RMS Acceleration and Displacement as measured by accelerometers and laser displacement sensor. Jt is expected that higher Acceleration and Displacement would cause more electrical power to be generated when the self-tuning mechanism is combined with energy conversion devices such as piezo-electric elements.
