Generation of Smart Power with the Aid of Piezoelectric Sensors

Abstract

Numerous methods exist for generating power using natural resources such as water, wind, thermal energy, and solar energy. Sunlight is a major source of energy. Despite this, the world's population is growing rapidly. There may be an increase in resource demand across the globe due to overpopulation. As a result, energy demand will also increase, but the resources used for this will decrease over time. Thus, saving energy or finding an alternative way to generate power conventionally is crucial. Nuclear, coal, and wind are the most common conventional methods. Alternative energy sources have become more popular for heat and electricity production due to environmental problems. Alternative energy sources include biomass, geothermal, wind, and solar energy used for producing electricity. Despite this, the power plants emit very harmful pollution, which is why there is a need to find another pollution-free power source. This proposed model can be used to produce power using a piezoelectric sensor in an eco-friendly manner. The piezoelectric sensor works by producing a potential difference of the same magnitude of force when pressure is applied to it. This potential difference is then converted into electrical energy. Therefore, for generating power, piezoelectric sensors are placed beneath the road. Power is derived from the mechanical stress applied to the sensors whenever vehicles or people pass. Thus, the power can be used for various applications like lighting streetlights, charging mobile phones, security cameras, etc.
