In recent times, electricity has become a great necessity for everyone and almost everything around the globe. The ever-growing population and increase in electronic devices have increased the rate of energy consumption. In a bid to meet this demand, all forms of energy are utilized and still undergoing research. This work aims at generating and harvesting electrical energy by converting mechanical energy from pressure exerted (footsteps) on the material into electricity by a phenomenon called piezoelectricity. A group of 40 piezoelectric crystals were constructed and connected via a parallel connection of 5 by 8. The piezoelectric crystals showed different results to varying weights and oscillations at a fixed time. These results were visible on the plot of voltage generated versus weight and on the plot of voltage generated to number of steps. These graphs showed that the greater the weight the more voltage and also more voltage is generated with increase in number of footsteps.
