Contact/non-contact sensor mesh for body temperature monitoring

In this study, a low-cost data acquisition (DAQ) system has been developed to measure the body temperature from multiple points using a sensor network approach. This system collects raw data with long-term recording and stores for further analysis. Contact and non-contact types of temperature sensors were used. The system was especially designed for measuring from head during electroencephalography (EEG) recordings. The system can record data during the normal daily activities because of its portability. Observing body thermo-regulation in a time period of 24 to 36 hours and finding the correlation with the ambient temperature requires very long time physiological recording. Thus, it has been made possible to record temperature everywhere and in day or night time without limiting the mobility. Using different type of temperature sensors and measuring the ambient temperature allows determining the temperature differences and the thermal response of body separately. As a result, a low cost, compact, portable, and durable measuring system with using two types of temperature sensors has been designed for considering easy and reliable measurements.
