PIEZOELECTRIC EFFECT DUE TO STEPPING
iezoelectricity is electrical energy generated from mechanical pressure. When the pressure is applied to an object, a negative charge is produced on the expanded side and a positive charge on the compressed side. Once the pressure is relieved, electrical current flows across the material. Electrical charge produced by the pressure of a single footstep is captured by floor sensors, convert to an electrical charge by the piezo material, which is usually in crystals or ceramics form and generate electrical energy through the generator. Lastly, it transmitted to the electrical storage device underground and stored as power source. Users are the main key of this design. One footstep can only provide enough electrical current to light up two 60-watt bulbs for a second, but as the number of people walking on the piezoelectric floor, greater number of energy would be generated. Hence, unlike the crowd at dance clubs and train stations, our site would not has that much people to make this piezoelectric flooring system to be efficient. Hence, our main focus of energy generative idea is the flapping panel, whilst this flooring panel would act as an add-on effect to prevent the waste of energy when users walking along the sculpture.
