Abstract

The green energy comes from natural sources such as wind, rain, sunlight, tides, plants of algae. Those sources of energy are renewable, meaning they are naturally replenished. By comparison, fossil fuels are a scarce resource that will take millions of years to produce and begin to decline with use. Also, renewable energy sources have much less environmental impact than fossil fuels, which contribute to climate change by producing emissions such as greenhouse gases as a by-product. Green energy uses energy sources that are readily available throughout the world, including in rural and remote areas which do not have access to electricity otherwise. Method used are piezoelectric sensors that connected in series parallel to the bridge circuit which consists of 17 units of Schottky diode. The piezoelectric sensors are been forced to generate energy and charge the 10µF 25V capacitor and also charging the 3.7V 40mAh LiPo battery after that the Arduino microcontroller will send the signal to the LCD display and display the battery voltage. For the result, the relationship between the voltage of capacitor and voltage of battery are directly proportional to the time taken and number of steps. Based on my analysis of data, the piezoelectric sensor is managed to charge the LiPo battery but its only can hold in a short time. For the final result of this smart footwear energy generator project, all objectives had successfully achieved. The piezoelectric sensor can energize and supply a voltage value and charging the battery but in a small quantity. Other than that, LCD successfully display the value of voltage from battery and capacitor clearly even though the reading is not precise as multimeter but it’s can show and read slightly the same.
