Title: Geometric Design of Capacitive Sensor for Liquid Membrane Detection
Abstract: A multi-spiral capacitive sensor is proposed to improve the sensor performance, and the relation between the geometric parameters design of the sensor and the sensor performance is discussed. Compared to traditional sensors, under the same measurement conditions, the electrical field distribution of the multi-spiral-shaped sensor is presented. The detail effects of the sensor design parameters, such as gaps between the sensor electrodes, the effective area and the geometry of the sensor plates are qualitative analyzed. The experimental results prove that the complex structure sensor can improve the measurement linearity, signal strength and measurement sensitivity.
