thermoelectric
熱電
解説 Definition
温度差を利用して電気を発生させる、または電気で温度差を作る技術に関すること。
Thermoelectric describes the connection between heat and electricity. It is used for materials or devices that create electricity from temperature differences, or that produce heating or cooling through electric current. This word is mainly used in science and engineering.
覚え方のコツ Memory Tip
thermo- は thermometer や thermal の「熱」、electric はそのまま「電気」。まず『熱＋電気が直結した語』と押さえると覚えやすいです。熱で電気を生む、逆に電気で温度差をつくる場面の両方に使われるので、片方向だけで覚えないのがコツ。electronics のような「電子回路」の話ではなく、temperature difference と electricity の変換技術を指す語。thermoelectric power generation, thermoelectric materials の形で見ると定着しやすいです。
Break it into two clear parts: `thermo-` for heat and `electric` for electricity. That gives you a direct memory hook: heat and electricity connected in one system. It is often used for technology that turns heat into electricity, or electricity into a temperature difference. Phrases like `thermoelectric materials` help fix it in context.
例文
Thermoelectric generators can convert waste heat from engines into usable electricity.
熱電発電機はエンジンの排熱を利用可能な電力に変換できる。
The spacecraft relies on thermoelectric power generated by a radioactive source.
その宇宙探査機は放射性物質から生成される熱電力に依存している。
Researchers developed a new thermoelectric material with unprecedented efficiency.
研究者たちはかつてない効率を持つ新しい熱電材料を開発した。

thermoelectric の語源・成り立ち Etymology
thermoelectric はギリシャ語 thermo-『熱』と electric『電気の』の結合で、electric はギリシャ語 elektron『こはく』にさかのぼります。thermal や electron と同じ根をもつので、『熱と電気がつながる』現象を名づけた語だと分かります。
Thermoelectric combines thermo-, from Greek thermos meaning "hot," with electric. Electric goes back to Greek elektron, "amber," because amber was linked to early studies of electricity. The word was formed to name things where heat and electricity are connected. Related English words include thermal, electron, and electricity.
