Abstract
The platform uses the electrochemical impedance spectroscopy (EIS) technique for pathogen detections. It includes sensor front end, stimulus generation, analog sensor data acquisition and conditioning, digital-to-analog conversion, back-end digital signal processing, wireless interface and a user phone app. The platform is powered by a USB based rechargeable battery at 3.3V. At a area cost of 28cm2. An average error of 2.6% is achieved compared to commercial counterpart.
