Abstract

Method to determine the entropy increase in a volume and the entropy flow through a surface. The invention relates to an entropy detector method comprising a pyroelectric sensor 1, which generates a current 6 proportional to a thermal variation 2, a temperature sensor 5, a charge amplifier 3 and a sensor data acquisition system 4. The invention allows to measure: i) the entropy variation in a volume and ii) the entropy flow through a surface according to the location of the sensor.
