INTRODUCTION
Renewable energy is energy that can be generated from natural processes and can be renewed. Piezoelectricity is a renewable energy that can be produced with the use of the piezoelectric transducer (Piezo Technology, n.d.). This research study aims to test the capability of Voltage Generating Prototype Road Plating Equipped with Piezoelectric Transducer to produce a voltage output from three different pressure. The research aims to produce electrical energy through the use of piezoelectric transducers.
METHODS
Two concrete plating with piezoelectric transducer, in series connection, were made. The plating had rubber bands, which will provide support for the pressure applied to the piezoelectric transducer. The other concrete was placed on top of the other concrete in which the object will apply the pressure. Three set-ups were used: concrete plating, concrete plating with man, and concrete plating with man on a bike. Three (3) trials with 3 replications was conducted for each set-up. The voltage output produced by the prototype was measured using a multimeter.
RESULTS
The results show that the man that walked across the concrete plating had the highest amount of voltage produced with an average of 239 mV. After the data analysis using one-way ANOVA, the data showed a p-value of 0.0000000000116. The p-value of the gathered data was less than 0.05. This means that there is a significant difference between the average amount of voltage produced by the piezoelectric transducer circuit for each setup in each trial.
DISCUSSIONS
From the gathered results, it was concluded that using piezoelectric transducers under road plating is applicable as an alternative source of electrical energy. The pressure from people walking above or riding a light vehicle can be converted into electrical energy. Thus, this study can be used at sidewalks and bicycle lanes where the mass of moving people can be used as an alternative electrical energy source.
