Wireless dual channel human body temperature measurement device

Human body temperature is influenced by many factors such as cognitive, emotional and psychological states. Temperature measurements can be done using analogue or digital electrical sensors. High sensitivity and high accuracy in measurements are usually provided by the analogue sensors that require sophisticated circuits for linearization/calibration and also for digitization. When compared with the analogue ones, digital sensors can also provide high sensitivity but lower accuracy although good enough for several medical applications. In this study, a portable device with wireless computer connectivity that provides noninvasive dual channel digital body temperature measurements has been developed. Trials with the device show that it is quite beneficial in measuring body temperature from ear canal. It may also be used to perform temperature measurements from mouth, armpit and anus.
