Abstract

A compact combination sensor is provided for physiological parameters, which can be worn behind the ear. The combination sensor has a heat flux sensor (1) for detecting two temperatures (Th1, Th2) for determining the body core temperature (Tc), an acoustic sensor (2) for measuring the heart rate (HR) and for detecting speech signals, as well as a measured signal evaluating unit (4, 5, 7). A communications interface (8) is provided for transmitting the processed data from the measured signal evaluating unit (4, 5, 7) to a communications unit (9) are located in the sensor carrier (11).
