Transition Edge Sensors (TES) are sensors that can measure tiny increases of temperature of order µK and are widely used to read out cryogenic calorimeters. However, delicate materials (e.g. with low melting point and/or hygroscopicity) can not undergo the process of fabricating such a sensor on their surface. To deal with this, the COSINUS-experiment developed the remoTES readout design, where the TES itself is placed on a separate wafer and the coupling of the absorber crystal to the TES consists of a gold bonding wire connected to a gold pad on the absorber. In this talk studies done for the optimization of the remoTES design using silicon crystals as a benchmark are shown.
