Abstract

This paper represents design, fabrication and characterization of non-invasive capacitive sensor for detection of different concentrations of bacteria such as Pseudomonas aeruginosa and Staphylococcus aureus in saline. The sensor was fabricated in printed circuit board (PCB) technology and it consists of a pair of interdigitated electrodes. In house measurement setup for testing and characterization of sensors has been developed. The characteristics of sensor- the capacitance as a function of frequency for a different concentrations of each bacteria are presented. The obtained results demonstrate different resonant frequencies for each dilution of Pseudomonas aeruginosa and Staphylococcus aureus in physiological saline.
