POWER GENERATION FROM WATER DROP USING PIEZOCERAMIC TRANSDUCER

There are various method of extracting energy from water drop for power generation such as using a dynamo or turbine. Another method to harness this energy is through a piezoceramic transducer which is based on the context of vibration energy harvesting. The core of this study was to create and evaluate the performance of locally fabricated piezoelectricity generator. The voltages were measured using a multi-tester and the volume of water drop was measured using graduated cylinder. The derived values were used to calculate the actual power generated at varying water height level. On the other hand, voltage coefficient was computed based on the mean voltage of the piezodisk over its maximum output voltage. The piezoelectricity generator yielded a mean voltage for H1 = 2.84V, H2 = 2.59V, H3 = 2.55V and H4 = 1.85V. These values corresponds to HI = 9.47%, H2 = 8.63%, H3 = 8.5% and H4 = 6.17 % efficiency. Moreover, the performance data produces a small amount of actual power for HI = 1.9 mW, H2 = 1.6 mW, H3 = 1.5 mW and H4 = 0.8 mW. However, it is recommended that the piezoelectricity generator can be further improved for future evaluation and analysis.
