I hae aqiured a piezo disk and LEDS but it will not power them. i do not know if it is the disk or an led. I tried the LED with AA AAA and D batteries but only turned on with 9V they are sea green
ninja.lion said:so how do all the videos on youtube of someone poking a disk and the led soldered to it lighting up work?
Can you provide a link to a good one?ninja.lion said:so how do all the videos on youtube of someone poking a disk and the led soldered to it lighting up work?

You tapped it while you had the voltmeter connected? Maybe that piezo is dead, do you have another one to try?ninja.lion said:i tried that no voltage
Piezoelectricity is the ability of certain materials, such as crystals, to generate an electric charge when mechanical stress is applied to them. This occurs because the stress causes a shift in the material's atomic structure, creating an imbalance of positive and negative charges which results in an electric field.
One of the main benefits of using piezoelectricity to power a LED is that it is a renewable and sustainable source of energy. Unlike traditional batteries, which eventually need to be replaced, piezoelectric generators can continue to generate electricity as long as there is mechanical stress applied. Additionally, piezoelectricity is a clean energy source and does not produce harmful emissions.
There are several materials that can be used to create a piezoelectric generator, such as crystals like quartz, tourmaline, and ceramic materials like lead zirconate titanate (PZT). These materials are chosen for their ability to produce a strong electric charge when mechanical stress is applied.
The amount of power generated from piezoelectricity depends on several factors, including the type of material used, the amount of mechanical stress applied, and the size of the piezoelectric generator. In general, piezoelectric generators are capable of producing small amounts of power, but advancements in technology are continuously improving their efficiency.
Piezoelectric generators can be used in a variety of applications to power LEDs, such as in wearable technology, sensors, and self-powered devices. They can also be used in environments where traditional batteries are not feasible, such as in remote locations or underwater. Additionally, piezoelectricity has potential uses in renewable energy sources, such as harvesting energy from footsteps or vibrations in machinery.
