Textile Sensor Surrogate Modelling using Sparse Identification

This paper addresses a possible surrogate model of a textile-based force sensor as introduced by Schuler et al., that is based on capacitance changes of conductive pads on the sensor surface caused by physical deformation. The proposed model is supposed to capture dynamic relationships between capacitance, force, and pull distance using a novel approach based on discrete Preisach hysteresis models in combination with Sparse Identifications of Non-linear Dynamics (SINDy), that is especially suitable for embedded systems applications.
