Industrial capacitance sensors and actuators

摘要

In-line monitoring of the integrity of industrial components is critical for determining overall system life and stability which in turn promotes safety for personnel and equipment. However, sensing is not the only step in the process, sensing and then subsequent response can create a full-loop interactive system to not only predict failure but also prevent its occurrence. Ideal measurement and response systems should be designed to minimize required material and processing adjustments to current standardized components. This research depicts methods and proof of concept for monitoring the integrity of industrial systems using capacitance sensors created from common industrial materials and manufacturing processes in three industrial applications: tires, hydraulic hoses, and seals. Furthermore, the work provides a means to create an actuation response using electroactive polymers composed of the same industrial materials providing a sensing and response loop. This article depicts three specific applications of this technology and industrial products that can be used to improve the reliability of human operated equipment.
