Core body temperature is the temperature of the internal organs that the body manages through the physiological processes of thermoregulation.  It is not a constant temp, as many people assume. It varies normally by a few degrees and can go as high as 104F during heavy exertion. High core temperature increases heart rate and puts a strain on the cardiovascular system, leading to decreased aerobic performance. In the extreme, elevated core temp leads to heat related illness and risk of serious injury or death. There are many valuable uses for continuous core body temperature monitoring.

Clinical

Infection and disease detection.  Monitoring sleep cycles and biorhythms.

Athletic Performance

Performance monitoring, training and safety. 

Occupational Safety

Heat illness detection.  For professions such as firefighters and soldiers.

Where is the Wearable for Measuring Core Body Temperature? 

Currently there is no non-invasive, wearable, wireless device that can continuously and accurately measure core body temperature in a variety of conditions. This is because the clinical standard for measuring core temperature is via rectal probes - not conducive to physical activity.

Non-Invasive Solution - gaugewear

With patented technology using radiometric thermometry, gaugewear is creating a wearable, non-invasive, core body temperature sensor. Radiometric thermometry determines temperature by passively measuring the electromagnetic waves emitted by the body. We can measure the radio waves emitted from inside the body to determine temperature several centimeters below the surface.

This could be a game changer.

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.
