: In this thesis, capacitive textile pressure sensors have been developed. The sensors were meant to be integrated into saddle pads and be able to measure the pressure between the saddle and horse. The aim of the thesis was to create a theoretical and practical based map on how a textile pressure sensor can be made. Capacitance was found to be the most suitable pressure sensitive technique to be implemented in a textile structure. The project was divided into two cycles, where the first cycle consisted of laminating capacitive textile pressure sensors of readymade fabrics in different thicknesses and sizes. After testing the pressure sensitivity of these laminates, it was concluded that a thin fabric with some compressibility was sufficient for making a textile capacitive pressure sensor. However, the area cannot be too small. The second cycle consisted of weaving capacitive pressure sensors as three layer structures. The pressure sensitivity of the sensors and the effect of moisture were tested. The results showed that most of the woven sensors were able to sense a 50g change in weight even after a 700g load was put on. The moisture and water tests showed that the pressure sensors must be protected from water and moisture. It was also discovered that there is a lack of knowledge in how textile structures and fibres behave under compression and release. Models of how textiles behave during pressure are needed to do correct transformations between compression and pressure and predict how the textile will behave during different pressures. / Program: Masterutbildning i textilteknik
