Technical term in physics and materials science; refers to the ability of certain materials to generate a temporary voltage when heated or cooled.
焦電気効果は、温度変化によって結晶に電圧が生じる現象です。
The pyroelectric effect is a phenomenon where a voltage is generated in a crystal due to temperature change.
Compound of 焦 (しょう, 'scorch' or 'heat') and 電気 (でんき, 'electricity'), literally 'heat electricity'. The term is a direct calque from English 'pyroelectricity' (from Greek 'pyr' meaning fire).
