Abstract
Disclosed herein are example embodiments of a transformative sensor apparatus that is capable of detecting and quantifying the presence of a substance of interest such as a specified bacteria within a sample via changes in impedance exhibited by a detection electrode array. In an example embodiment, sensitivity is improved by including a focusing electrode array in a rampdown channel to focus a concentration of the substance of interest into a detection region. The focusing electrodes include an opposing pair of electrodes in a rampdown orientation. The focusing electrode may also include tilted thin film finger electrodes extending from the rampdown electrodes. In another example embodiment, trapping electrodes are positioned to trap a concentration of the substance of interest onto the detection electrode array.
