The goal of our project is to create a device that can noninvasively measure internal body temperature of a person. This device must be wireless, wearable and non-intrusive so that it can be worn when participating in physical activities. Currently there exists no way to measure a person's internal body temperature noninvasively. Current noninvasive measurements of body temperature are limited to skin surface temperature, which due to thermoregulation in the body, does not indicate internal body temperature. The ability to noninvasively measure internal body temperature has many applications in the medical, research, sports, and military fields. There is also a growing interest in the personal health monitoring field.

The method we use to noninvasively determine internal body temperature involves detecting black body radiation that is emitted from a person. We take the power emitted by the black body radiation of a person and apply a weighting function that is calibrated to the person to calculate their internal body temperature. Our project relies heavily on the areas of RF signals, RF circuit design and digital signal processing. We are building our own probe, radiometer, and power/MÅ·ÃÀ¿Ú±¬ÊÓƵ board in an effort to make our device as small and energy efficient as possible since the device is intended to be worn. The wearable measuring device or body pack will connect to a computer over Bluetooth Low Energy where the user can use the application that we create to view internal body temperature and log the temperature data.
