Abstract

An integrated chemical sensor chip comprises on or integrated in a common substrate a chemically sensitive layer and a heater heating the sensitive layer. In addition, a memory is provided for the storage of a measurement routine, the measurement routine comprising instructions defining a heating process over time and instructions defining one or more measurement points in time. An I/O interface is provided for receiving a trigger for the measurement routine and for supplying a result of the measurement routine. An engine controls the heater and measures a resistance of the sensitive layer according the instructions of the measurement routine.
