Monitoring the impact of sleep deprivation on thermoregulation re- quires a careful measurement of skin temperature across the human body to have precise knowledge and understanding of the stabil- ity of circadian rhythms, the 24-hour cycles of biological activity. However, medical measurements and clinical trials are often car- ried out in controlled lab settings, which limits the realism and the duration of data collections, and increases significantly their costs. We aim to provide medical researchers studying the stability of the circadian rhythms with a tool for higher quality data collections. We design and develop a wireless unobtrusive monitoring system for accurate body temperature measurements to be worn by patients for several weeks while they live their normal life. Obtaining a long-lasting highly-accurate measurement system is challenging, as energy and computational resources are severely constrained in miniaturized wearable sensor nodes. We develop a prototype of an active temperature measurement system with 0.02 ◦ C accuracy, a lifetime of up to 3 weeks, and real-time feedback to a remote medic. Our preliminary experiments show that we can identify the circadian rhythms also in non-ambulatory environments, indicating that our tool could become a valuable asset for medical research.
