Methods and apparatuses for an oxygen consumption monitoring system are disclosed herein. The invention further provides a method for the synthesis of these polymers. The polar component is analyzed for one or more biodiesel chemical components selected from the group consisting of plant sterols, fatty acid methyl esters, cetane, and combinations thereof, which relate to a degree of engine oil contamination. The ligands are attached to the final layer of the assembly. Accordingly, a single transducer device can be tuned for either transmitting or receiving a corresponding wireless signal. With this configuration, even when the activation period of the external reset signal is long, the time for which a current flows through the fuse element can be shortened, thereby making it possible to reduce a current consumption at the time of a reset operation.
