  • Patent number: 9168185
    Abstract: An absorbent article including a temperature sensor, and at least one temperature change material arranged such that it is capable of affecting a temperature change due to a supply of excrement, and such that said temperature sensor is capable of being responsive to said affected temperature change. Also disclosed is a system for detecting a supply of excrement into an absorbent article, the system including an absorbent article being arranged to generate an output signal representative of the temperature, and a processing unit adapted to process an output signal generated by the temperature sensor. The processing unit is adapted to determine a change of temperature, wherein said change of temperature is affected by the temperature change material, and to detect a supply of excrement into the absorbent article based on the change of temperature.
