Abstract:Regardless of the importance of air filtering, there are quite few technologies to observe the purity of a filter. Optimizing the filter replacement cycle is necessary from the cost efficiency and the ecological point of view, being a motive for sensor technology development. In this paper, we propose and demonstrate a concept for that purpose. A capacitive sensor element is screen-printed directly onto the filter surface and assembled in 3D printed frame to observe the particle accumulation while the filter i… Show more
