Abstract
A biosensor is provided. The biosensor is used to sense a biological sample and has a code representing features of the biosensor. The biosensor includes a substrate and a conductive layer. The conductive layer is disposed on a first side of the substrate and includes a first conductive loop and a second conductive loop. The first conductive loop is formed between a first node and a second node and has a first impedance. The second conductive loop is formed between the second node and a third node and has a second impedance. The code is determined according to a comparison result between the second impedance and the first impedance.
