In this video we'll take a look at thermal radiation, one of the three modes of heat transfer along with conduction and convection. We'll start by covering electromagnetic waves, the Stefan ...

Because no particles are involved, radiation can work through the vacuum of space. This is why we can still feel the heat of the Sun even though it is 150 million km away from the Earth.

In trials using phantom and living subjects in room-temperature settings, the PTG platform showed fully passive and reliable detection of human vital signs such as temperature, heart rate and ...
