Sorry, no etymologies found.
At its heart are two opposing "pyroelectric" crystals that create a strong electric field when heated or cooled.
It is also strongly pyroelectric which means that temperature changes can cause the development of positive and negative charges within the crystal.
The crystal is one of a group of pyroelectric materials, so named because they create electric fields when they change temperature.
Godfried has used the invisible instrument in a number of his performance pieces over the years, including Songbook illustrated above, and the ongoing electronic opera TechnoFaustus, which also uses "pressure transducers, contact microphones, acceleration-sensing devices, pyroelectric transducers... and 1 to 3 naked techno or break dancers".
It has microphones, and optical and pyroelectric sensors to detect people.
Now, according to a report in Live Science, researcher Igor Lubomirsky at the Weizmann Institute of Science in Rehovot, Israel, and his colleagues have discovered another way to control the freezing point of water - via what are called quasi-amorphous pyroelectric thin films.
