Abstract
The device comprises a heat-sensitive element which is heated to a controllable extent so as to keep it at a predetermined temperature, for example, average body temperature. Detector means measure the power or energy required to keep the heat-sensitive element at this predetermined temperature, thus providing a signal indicative of the thermal comfort conditions of the environment. The heat-sensitive element has a general elongated shape so that it can be inserted, for example, into a motor vehicle safety belt, ensuring that the indication obtained indicates the general thermal comfort conditions throughout the entire region of the environment in which the heat-sensitive element extends.
