Multifunctional Sensor Technology

The classical and standardized methodology for measuring acidity levels requires mandatory calibration of the measuring instrument using reference solutions with acidity values of pH 4 and pH 7 prior to any measurement. Accordingly, the proposed experimental measurement system also necessitates calibration mechanisms before performing control measurements, which significantly increases the overall measurement time.

During the study, various types and designs of sensors (solenoids) were tested, including a planar sensor configuration used at the final stage of the experiments. A comprehensive global patent search confirmed that this type of sensor, its application for acidity measurement and monitoring, as well as its structural implementation, were employed for the first time.

The term biosensor traditionally refers to a device in which biological materials—such as enzymes, tissues, bacteria, yeasts, antigens/antibodies, liposomes, organelles, receptors, DNA, and viruses (including coronaviruses)—directly respond to signals generated by the proposed sensor, producing a resonant output functionally linked to the presence and concentration of the target component.
