Piezoelectricity

1. Piezoelectricity

2. What is Piezoelectricity? Phenomenon of electric charge that accumulates in certain solid materials – such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins – in response to applied mechanical stress.

3. Components Piezoelectric Transducers Full Wave Bridge Rectifier ( made with Power Diodes – IN4007 ) 1000 μ F, 50 V Electrolytic Capacitor Breadboard Jumper Wires LEDs

4. Piezoelectric Transducer Any device that can convert any form of physical quantity into an electrical signal, which can be used for measurement. Used as the ene r gy source for this project.

5. Power Diode Nonlinear passive electronic component composed of two terminals: the anode and the cathode. It makes the electric current pass in only one direction and blocks it completely in the other direction. Used to build a full wave bridge rectifier to rectify AC to DC.

6. Electrolytic Capacitor Capacitor that uses an oxide film made of aluminium, tantalum, or other oxidizable metal as a dielectric because of its potential for large capacitance, this type of capacitor is used extensively in power supply circuits and similar applications. Used to store electricity and supply it whenever possible to the appliances in this project. Using 1000 μ F, 50 V Electrolytic Capacitor

7. Breadboard A breadboard is essentially the foundation to construct and prototype electronics. A breadboard allows for the easy and quick creation of temporary electronic circuits or for carrying out experiments with circuit design. Used for building the electric circuit.

8. Jumper Wires A jumper wire is an electric wire that connects remote electric circuits used for printed breadboards. By attaching a jumper wire to the circuit, it can be short-circuited and jump to the electric circuit. Used to connect parts of the circuit.

9. LED LED is a semi conductor diode that when supplied energy produces light energy. Used to show the working of the project.

10. Concept To harvest traffic energy to generate electricity. Mechanical pressure applied by moving vehicles on a road can be converted to electric energy if roads are paved with piezoelectric transducers. The harvested energy can be transferred back to the grid, used to recharge batteries, or used for specific road infrastructure purposes.

13. Advantages Sustainable: Piezoelectricity is clean and renewable energy. No external power source other than the force produce by vehicles moving on the road is required. Easy to install as they have small dimensions. Responsive to high frequencies which makes them great during the most demanding situations Highly flexible as they can be constructed into various amount of shapes and sizes.

14. Disadvantages They produce a small amount of electric charge. Environmental conditions affect the performance. No output in static conditions.
