ABSTRAK

The article deals with a research activity to design and to build an electricity signal generator mechanism based on a multi-layer piezoelectric method where the energy source is from translational-harmonic vibration. In the developed mechanism an elastic mass consists of piezoelectric material and silicon rubber layers is deformed compressed due to an impact force which comes from vibration source. Piezoelectric material is chosen because it can be manufactured into a compact mechanism. And a multi-layer piezoelectric method is used to increase the capability of the material to produce electricity. In the research the varied parameters were the clearance gap 2 mm 4 mm and 6 mm the frequency 120 rpm 180 rpm and 240 rpm and the number of piezoelectric material layer 1 layer 2 layers and 3 layers. The experiment showed that the voltage which could be harvested from the mechanism was influenced by clearance frequency and the number of piezoelectric material layer. The maximum voltage density which could be harvested was recorded as 11.75mV cm3 obtained from the mechanism at clearance of 6 mm frequency of 240 rpm and 3 layers of piezoelectric material.
