DESIGN OF AN ENERGY HARVESTING SYSTEM USING PIEZOELECTRIC MATERIALS

Energy harvesting by using piezoelectric materials is one of the most widely used techniques for conversion waste energy into useful. Using this technique, generated vibration from machines can be converted useful electrical energy. In paper, an system that supplies power low-power consumption devices has been designed. The experimental model consists a rotating machine generates mechanical vibrations actuate cantilever beam and transducer as sensor harvesting. aim to generate greater output, which could achieved obtaining maximal strain given frequency range source. variable multiple frequencies have used. Euler-Bernoulli method, dimensions calculated so its natural matches operating frequency. By reaching resonant point beam, designed generated.
