Abstract
An inductive-capacitive (LC) wireless sensor for the detection of toxic heavy metal ions includes inductors and interdigitated electrodes (IDE) in planar form. The sensor is fabricated by screen printing silver (Ag) ink onto a flexible polyethylene-terephthalate (PET) substrate to form a metallization layer. Palladium nanoparticles (Pd NP) is drop casted onto the IDEs to form a sensing layer. The resonant frequency of the LC sensor is remotely monitored by measuring the reflection coefficient (S) of a detection coil (planar inductor). The resonant frequency of the LC sensor changes with varying concentrations of heavy metals such as mercury (Hg) and lead (Pb) ions. Changes in the resonant frequency are used to detect the presence and/or concentration of heavy metal ions.
