Is there anyone to help me??

Question

Actually i need guidance in a project work.Is there anyone who got some idea on piezoelectric materials???And my project is all about,saving electricity produced by piezoelectric materials.Please do mail me,if you can help me any way!Love to hear from you.

Thank you all(in advance).Have a great day:)

Answer 1

The piezoelectric effect describes the relation between a mechanical stress and an electrical voltage in solids.

It is reversible: an applied mechanical stress will generate a voltage and an applied voltage will change the shape of the solid by a small amount (up to a 4% change in volume).

In physics, the piezoelectric effect can be described as the the link between electrostatics and mechanics.

The piezoelectric effect occurs only in non conductive materials. Piezoelectric materials can be divided in 2 main groups: crystals and ceramics. The most well-known piezoelectric material is quartz (SiO2).

Scientists from CEA/Leti-Minatec, an R&D institute in Grenoble, France, specializing in microelectronics, have recently developed a system that recovers the vibration energy from a piezoelectric structure impacted by a falling raindrop. The system works with raindrops ranging in diameter from 1 to 5 mm, and simulations show that it’s possible to recover up to 12 milliwatts from one of the larger “downpour” drops.

“Our work could be considered as a good alternative to power systems in raining outdoor environments where solar energy is difficult to exploit,” Thomas Jager told PhysOrg.com. He explained that the system could be used for both mobile outdoor devices as well as indoor power. “For example, we intend to develop remote sensor nodes in cooling towers, but abandoned sensor networks are also one of the foreseen applications for this type of system.”

you can use the piezo electric material under the zebra crossings and entrance of your college itself and store it by using battery arrangement and use it for your room... this is just a blurred image of what you have to do... all the best
