• Piezoelectric Generator

    Piezoelectric materials generate electricity when they are mechanically deformed. In this video we show how this can be used to make a simple circuit that stores the energy in a capacitor and lights a LED. Capacitor is 20 uF @ 25 volts and resistor is 2.2 k.

It is just convert mechanical efforts such force and pressure converts into electricity. The word piezoelectricity means electricity resulting from pressure.

  • how to make piezoelectric generator at home

    Make a foothold development using piezo electric element. Little energy and can make electricity. Small movements, wind and step. Piezoelectric generators is very good energy harvesting. A piezoelectric cantilever is mounted directly above a base of the radioactive isotope nickel-63. All of the radiation emitted as the millicurie-level nickel-63 thin film decays is in the form of beta radiation, which consists of electrons. As the cantilever accumulates the emitted electrons, it builds up a negative charge at the same time that the isotope film becomes positively charged. The beta particles essentially transfer electronic charge from the thin film to the cantilever. The opposite charges cause the cantilever to bend toward the isotope film. Just as the cantilever touches the thin-fil...

All of the radiation emitted as the millicurie-level nickel-63 thin film decays is in the form of beta radiation, which consists of electrons. As the cantilever accumulates the emitted electrons, it builds up a negative charge at the same time that the isotope film becomes positively charged. The beta particles essentially transfer electronic charge from the thin film to the cantilever. The opposite charges cause the cantilever to bend toward the isotope film. Just as the cantilever touches the thin-film isotope, the charge jumps the gap. That permits current to flow back onto the isotope, equalizing the charge and resetting the cantilever. As long as the isotope is decaying - a process that can last for decades - the tiny cantilever will continue its up-and-down motion. As the cantilever directly generates electricity when deformed, a charge pulse is released each time the cantilever cycles. Radioactive isotopes can continue to release energy over periods ranging from weeks to decades. The half-life of nickel-63, for example, is over 100 years. Thus, a battery using this isotope might continue to supply useful energy for at least half that time. Researchers have demonstrated devices with about 7% efficiency with high frequencies of 120 Hz to low-frequency (every three hours) self-reciprocating actuators.

An Israeli company has come up with a way for some of the biggest energy consumers on the planet - cars, trucks and ordinary people - to generate energy by simply doing what comes naturally: moving across a surface. By embedding generators into roadways and sidewalks, Innowattech (inno-watt-tech) has found a way to turn pressure into electricity. [Notes:Haim Abramovich, head of Innowattech] WE ARE TAKING THAT ENERGY THAT IS GOING TO WASTE AND TRANSFORMING IT BACK INTO USEFUL ENERGY. THIS IS THE MAIN MOTIVATION OF USING PIEZOELECTRIC (MATERIAL) EMBEDDED UNDER THE ASPHALT." Piezo (PY'-zoh)-electric elements - commonplace in everything from doorbells to speakers - are capable of generating an electric signal based on pressure. So for every car tire that passes over the element, a current is generated. And the concept isn't limited to roadways. [Notes:Haim Abramovich, head of Innowattech] "PEDESTRIANS CAN PROVIDE THE PRESSURE FOR THE PIEZOELECTRIC GENERATORS TO PRODUCE ALSO ENERGY. THE PROBLEM IS THAT THEIR PRESSURE IS LESS COMPARED TO VEHICLES. BUT THEY CAN COMPENSATE BY BIG NUMBERS OF PEDESTRIANS. THIS IS THE GAME. IF WE HAVE A LOT OF PEOPLE WALKING ON TOP OF OUR PIEZO-GENERATOR WE CAN PROVIDE ENERGY. NOT IN THE SAME AMOUNT AS THE CARS, BUT FOR OTHER PURPOSES." Innowattech believes it can generate energy up to 50% cheaper than solar generated fuel, without the costs of the associated infrastructure. While no concrete plans are in place to start implementing the technology, Innowattech says it is in negotiations to begin embedding generators in Israeli roads.
