The term defines a material possesses electrical potential under different in temperature. That means we can harness power. That means we can make engine with a near 100% efficiency.
uart said:No the efficiency of pyroelectric energy conversion is still well less than 100%. Was that your point?
The Pyroelectric effect is a phenomenon where certain materials, such as crystals and ceramics, generate an electrical charge when they experience a change in temperature.
The Pyroelectric effect is based on the principle of polarization, where the positive and negative charges in a material are separated. When the temperature of the material changes, the movement of the molecules causes a shift in the polarized charges, resulting in an electrical charge.
The Pyroelectric effect has a wide range of applications, including motion sensors, thermal imaging cameras, and energy harvesting devices. It is also used in the production of infrared detectors and as a method for measuring temperature changes.
Yes, the Pyroelectric effect can be reversed by applying an external electric field to the material. This causes a change in the polarized charges, resulting in a change in temperature. This is known as the reverse Pyroelectric effect.
One potential drawback of the Pyroelectric effect is that it is not a constant source of energy. The electrical charge generated is dependent on the temperature changes, so the amount of energy produced may vary. Additionally, some materials used in the Pyroelectric effect are expensive and difficult to produce.
