A Schematic of AST using inductively coupled communication between the LC sensor and detection coil connected to EIS. The diluted bacterial culture with desired antimicrobial added is aliquoted into individual wells on a 96-well plate. The sensor wrapped around the internal walls of the well plate communicates wirelessly with an EIS analyzer to capture bacterial growth. B An illustration of the IDC and its parameters, where N is the number of digits in total, ɭ is the length of each digit, D is the gap between digit, and W is the width of the digits. C An illustration of the resonant circuit design, where the inductors represent the coils and the parallel resistor R1 and capacitor C1 represent the IDC on the sensor side, with Zsensor representing the total impedance of the coil and the IDC. On the scanner side, Zint is the intrinsic impedance of the coil, Ztotal is the total measured impedance of the coil. Also included is a signal generator/analyzer (EIS)
