Measuring device and method for making same

摘要

A measuring device for measuring or examining physiological parameters on biocomponents includes an FET sensor 5 whose electrical protective layer 12 is roughened or has a structured coating 15. The structuring of the active sensor contact surface 12 is adapted to the outer contour and topography of the biocomponent in question, so that a better possibility is available for anchoring the biocomponents to the contact surface 24 forming the FET protective layer of the sensor 5.
