Very Large Arrays of Bipolar Electrodes.

摘要

This project focuses on understanding the basic principles of bipolar electrode (BPE) arrays for chem/bio sensing applications. During this project period, we developed a self-powered, microelectrochemical sensing platform that reports its output using an electrochromic display. Additionally, we have demonstrated a new method to fabricate very inexpensive BPE devices in less than one hour using wax printing to define the architecture, a paper substrate, and carbon paste electrodes. Finally, we fabricated and tested BPE arrays that span two microchannels and discovered some very interesting principles that add value to this sensing technology. We also showed that the latter has excellent sensing capabilities. These studies are aimed at reducing the cost of sensors based on BPEs, while simultaneously increasing their simplicity and directing them toward targets of interest to the DoD.
