This paper presents the development of a novel one-side-electrode-type fluidic-based capacitive pressure sensor. A pressure sensor using a one-side-electrode and an implementation of electrical double layer capacitance concept was proposed. Mechanical analysis of the membrane was carried out using the finite-element analysis in terms of deflection and Mises stress. A sensor with a circular membrane radius of 3.2 mm, membrane thickness of 0.8 mm, microchannel thickness of 0.5 mm, and microchannel width of 0.5 mm was fabricated using polydimethylsiloxane. The validation was made between the analytical and experimental results for fluid mechanisms inside the sensor. This showed that the displacement for all types of liquid, including methanol, ethanol, and silicon oil was linearly aligned. Methanol was chosen as an electrolyte due to its liquid properties, such as low surface tension and dielectric permittivity. From the experimental results, the operating frequency, response time, and sensitivity of the sensor were 1.2 kHz, 0.12 s, and 0.77 pF/kPa, respectively. The effects of vibration, temperature, and lifetime were also discussed in this paper.Index Terms-Capacitive pressure sensor, electrical double layer, PDMS, electrolyte.

The excellent stability and anti-interference of the flexible arrayed glucose sensor based on microfluidic framework were successfully fabricated in this research. First, the ruthenium dioxide sensing membranes were deposited on the polyethylene terephthalate by the radio frequency sputtering technology. Because the ruthenium (Ru) was better catalyst which commonly used in the hydrogenated reaction, the Ru was chosen as the sensing membrane. Second, the conducted wires and the insulation layer were prepared by screen-printed technology. Nafion could increase the stability and prevent the interferences from passing the sensing membrane. Finally, the mixed solution was doped on the sensing membrane by entrapment method that the glucose sensor was successfully fabricated. In order to get the low consumption and decrease required volume of fluid, we combined the flexible arrayed glucose sensor and the microfluidic framework. The sensitivity, stability and anti-interference of glucose sensor based on the microfluidic framework were investigated. According to experimental results, the linearity was 0.994 and the average sensitivity was 0.192 mV/(mg/dL) at the best flow rate of the dynamical condition (20 µ L/min).Index Terms-Anti-interference, flexible arrayed glucose sensor, microfluidic framework, ruthenium dioxide, radio frequency sputtering technology, nafion Manuscript
