Wireless skin temperature measurement system for circadian rhythm monitoring

Nowadays a significant part of the population suffers of sleep disorders, so the dynamic long term monitoring of skin temperature during sleep is very useful for analysis and understanding the circadian rhythm. In this paper we describe the realization of a patient skin temperature monitoring system, based on wireless devices, capable to measure and transmit the patient´s skin temperature to a central monitoring station. The use of the proposed system is suitable for remote continuous long-time patient monitoring, in-hospital or at-home, as a part of a diagnostic procedure or during recovery. The described system uses custom developed wireless temperature measurement devices that perform the temperature measurements and wirelessly transmit them to the monitoring station. A graphical user interface running on the central monitoring station was developed, used for displaying the measurements and alerts, when patient temperature values exceed the preset limits.
