Abstract
One example discloses a substance detection device, including: a substrate configured to carry a substance; wherein the substrate has a length and a substance loss along the length of the substrate; a test region coupled to the substrate and configured to bond to at least a portion of the substance; a sensor coupled to the substrate at a fixed location along the length and having a sensing signal output; an integration circuit coupled to the sensor and configured to integrate, over a time interval, a signal from the sensing signal output; and a detection circuit coupled to the integration circuit and configured to output a substance detected signal if the integrated sensing signal output signal deviates from the substance loss corresponding to the fixed sensor location.
