Microthermal

"Microthermal" is a big word that means something very small that produces heat. Just like how you feel warm when you stand close to a hot stove or heater, microthermal things can make things around them warm too.

Microthermal things are so tiny that you can't see them without a special machine called a microscope. They are often used in things like microchips, which are like little computers that can fit in your pocket or even on your wrist.

When microthermal things get really hot, they can make the microchip stop working correctly. So scientists are always trying to figure out ways to make sure the microthermal things don't get too hot and mess up the microchip.

Overall, microthermal things are small but very important for things like computers and technology to work correctly.
