Measuring the Waves
All matter emits energy called thermal, or black body, radiation. That radiation follows a precise distribution that is defined by temperature. This is the same radiation measured by infrared thermometry that most people are familiar with. The difference in radiometry is in the frequency of operation. Infrared waves do not pass through the body, so they can only be used to measure surface temperature. By measuring the thermal radiation in the microwave band with an antenna on the skin, we can detect the signal from inside the body to determine temperature several centimeters below the surface. gaugewear’s proprietary technology allows accurate measurement through multiple tissue layers in a small form factor.
