| Summary: | The aim of this paper is an investigation of the additive manufacturing for the realization of a low-cost sensor and its application for force measurements. The proposed sensor consists of an inductor, an elastic spacer and a smooth ferrite plate. The inductor is fabricated by 3D printing technology. The spacer is realized in the form of an elastic mesh which was realized by employing 3D printing technology for mold fabrication in which is poured liquid silicone elastomer Ecoflex. The commercially available ferrite material is used as a magnetic part of the sensor. The dimensions of the developed sensor with casing are 25.2 x 29.3 x 7.7 mm3. The working principle of the sensor bases on the changes of inductance, when the distance between the inductor and the ferrite decreases due to the compression of the spacer with applied force. The proposed sensor is designed, fabricated and finally characterized within the force range from 0 to 2 N. |
