A pyroelectric material generates a voltage when its temperature changes.

Definition

1. Adjective:
   • Relating to or exhibiting pyroelectricity: Describes a material or property that generates an electric charge in response to a change in temperature.

Usage

• The term "pyroelectric" is used as an adjective to describe materials, effects, or devices. It is typically placed before a noun (e.g., pyroelectric material) or used in a predicate after a linking verb (e.g., The effect is pyroelectric).

Examples

• Adjective:
  • Certain crystals, like tourmaline, exhibit a strong pyroelectric effect.
  • The sensor uses a pyroelectric material to detect infrared radiation from body heat.
  • Pyroelectric detectors are commonly used in motion sensors.

Advanced Usage

• Pyroelectric Coefficient: A specific measurement quantifying the strength of the pyroelectric effect in a material.
  • Scientists measured the material's pyroelectric coefficient to assess its suitability for thermal imaging.

Variants and Related Words

• Pyroelectricity (n): The property or phenomenon of generating an electric charge due to temperature change.
  • Pyroelectricity is a characteristic of non-centrosymmetric crystals.

Synonyms

• Thermoelectric: (Note: While related, "thermoelectric" generally refers to the direct conversion of temperature differences to electric voltage and vice versa, which is a broader category that can include pyroelectric effects under specific conditions. They are not perfect synonyms.)

Different Meanings

• The word "pyroelectric" is a technical term with a single, specific meaning related to the generation of electricity from heat change. It does not have common idiomatic or figurative uses.
