The CRESST experiment aims at the direct detection of sub-GeV dark matter particles via elastic scattering off nuclei in different target crystals at cryogenic temperatures. Each detector consists of an absorber crystal and a Transition Edge Sensors (TES), which measures the temperature variations caused by an energy deposition in the crystal. The TES are made of tungsten thin films and they are operated in the middle of their superconducting transition, at around 15 mK. These very sensitive detectors allow for a leading energy threshold worldwide. The studies on the TES sensor design and its development at the Max Planck Institute for Physics are presented.
