Monitoring body temperature is useful for evaluation of the risk of urban thermal environment. This study aims to develop a compact skin temperature and a core body temperature instrument. They consist of compact and energy-efficient data logger (30 x 20 x 15 mm in size, 6.5 g in weight) and specific thermistors. The skin temperature instrument uses a compact thermistor with small heat capacity and that of core body temperature is an earplug-type thermistor which measures auditory temperature representing brain blood. The accuracy of the skin temperature is 0.3 °C with better response time and less influence of solar radiation than conventional cutaneous instrument. The accuracy of the body core instrument is 0.2 °C. These instruments enable the 24-hours continuous measurement under the subject's daily life and thus contributing the precaution of heat stroke and the evaluation of thermal comfort in urban districts.
