Definition

1. Adjective:
   • Relating to pyroelectricity: Describes a property of certain materials that generate an electrical charge in response to a change in temperature.
   • Exhibiting pyroelectricity: Used to characterize materials or phenomena that demonstrate this specific thermoelectric effect.

Usage Examples

• Adjective:
  • The sensor uses a pyroelectrical crystal to detect minute temperature fluctuations.
  • Researchers studied the pyroelectrical response of the new ceramic compound.

Advanced Usage

• Technical Context: The term is primarily used in physics, materials science, and engineering to describe the inherent property of non-centrosymmetric crystals.
  • The pyroelectrical coefficient is a key parameter for evaluating infrared detector materials.

Variants and Related Words

• Pyroelectric (adj): The more common variant, identical in meaning to 'pyroelectrical'.
  • Pyroelectric materials are used in motion sensors.
• Pyroelectricity (n): The noun form denoting the physical phenomenon itself.
  • The device operates based on the principle of pyroelectricity.

Synonyms

• Thermoelectric (adj): Relating to the direct conversion of temperature differences to electric voltage and vice versa. (Note: This is a broader category; pyroelectricity is a specific type of thermoelectric effect.)

Related Phrases

• Pyroelectrical effect: The specific phenomenon where a temperature change induces a temporary voltage in a material.
