Sensor arrangement for a packaging of a medicament

摘要

The present invention relates to a sensor arrangement to monitor at least one ambient parameter (24), the sensor arrangement comprising: - a first layer (12) exhibiting a first electrical conductivity, and - at least a second layer (14) exhibiting a second electrical conductivity different than the first electrical conductivity and being at least partially in direct contact with the first layer (12), - wherein the first and the second layer (12, 14) in an initial configuration comprise different concentrations of a diffusible component (22), having an impact on the conductivity of the first and/or the second layer (12, 14).
