Title

An intelligent fluidic dissolved oxygen sensor system by electromechanical actuation method

Author

Abstract

"Dissolved oxygen sensors are extensively used in many fields of industrial processes, medical diagnoses, and environmental surveillance. However, several significant drawbacks of the sensor still exist, such as the baseline drift and sensitivity degradation over time, which requires periodic time-consuming calibration procedures and subsequently a high maintenance. A novel method has been demonstrated in this study to overcome these problems by improving the dissolved oxygen sensor performance. A simple sensor system, consisted of a fluidic structure and electrolysis electrodes, is used to manipulate the oxygen calibration environment within the fluidic channel. Electrolytically generated oxygen and hydrogen bubbles play two roles in this integrated fluidic sensor system"--Abstract, leaf iii.
