Abstract
Devices and methods for detecting the presence and/or monitoring a movement of an analyte contained in a medium. More specifically, a microcapacitive sensing system is provided that includes a planar micro-capacitive sensor array for detecting the presence of an analyte in a sample media. The sensor structure for sensing recognizing or tracking material movement includes a top planar substrate having a first array non-contacting planar conductive electrodes and a bottom planar substrate having a second array of non-contacting planar conductive electrodes overlapping corresponding aligned electrodes in the first array. The overlapping conducting electrodes are triangular shaped to maximize perimeter-to-area ratio. The first and second planar substrates are parallel and sealed to define a volume therebetween for receiving a medium including the analyte to be detected or monitored. The sensing of movement accomplished by measuring a capacitance change between electrodes in the top substrate and aligned electrodes in the bottom substrate.
