Abstract
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.

Technologies and sensing mechanism for monitoring and measuring the force in various applications are realised: fiber-optic sensor for biomechanical measurement, the 3D printed force sensor fabricated by a digital light processing and high temperature resin, and an inkjet-printed strain gauge made from poly(3,4-ethylenedioxythiophene) polystyrene sulfonate ink, a flexible polymer tactile sensor with embedded multiple capacitors for normal and shear force measurement.. Numerous sensors consist of various types and forms of smooth ferrites which are fabricated for specific sensing applications. In Ref. 4 sensors for displacement measurements are developed using the heterogeneous integration process of traditional PCB (Printed circuit board) and LTCC (Low temperature co-fired) technology with a flexible polyimide foil as membrane and a ferrite disk attached to it. The self-resonant frequency modulation of an integrated coil caused by the relative displacement of a ferrite core is used for the fabrication of passive force sensor..
