Sensor device

A sensor device, comprising:

• a measurement chamber having at least a first wall, the measurement chamber including a plurality of analyte sensors;
• wherein the measurement chamber allows a fluid to be analyzed to interact with each of the plurality of analyte sensors when the fluid is accommodated within the measurement chamber;
• the measurement chamber having an inlet configured to receive the fluid to be analyzed and an outlet configured to allow the fluid to exit the measurement chamber after having interacted with the plurality of analyte sensors;
• the measurement chamber defining a sample volume for accommodating the fluid to be analyzed, the sample volume extending at least between the inlet and the outlet;
• and
• a heating element including a first portion and a second portion, the heating element being configured to heat the fluid accommodated within the measurement chamber, the first portion being closer to the inlet of the measurement chamber than the second portion,
• wherein the first portion comprises a larger trace density than the second portion to provide a larger heating effect along the first portion than along the second portion.
