For the integration of sensor components into ceramic-based implants it is of importance to create a reliable sensor-tissue interface. But an implantable sensor interface requires a set of properties: Such as biocompatibility, antifouling properties bio-stability and ion permeability. Hydrogels in general have promising qualities towards an application in this context. To screen different hydrogel coatings a method is needed which allows testing a broad range of materials in relation to the implants' other components. This is not always possible at an early stage of research. Therefore a test chip was developed enabling a parallel screening of hydrogel sensor coatings towards bio interaction and the testing of technically relevant properties using implant material.
