Micromechanic sensor element, electric circuit and sensor array comprising a plurality of micromechanic sensor elements

摘要

A micromechanical sensor element for recording the bonding of molecules to the micromechanical sensor element. The sensor element having a substrate and at least one electrical terminal. There is also an oscillatable element that is coupled to the electrical terminal in such a manner that an electrical variable that characterizes the oscillation behavior of the oscillatable element may be provided at the electrical terminal. Further, there is a molecule coupling layer, arranged in such a manner that molecules may bond to the molecule coupling layer. The molecule coupling layer is coupled to the oscillatable element in such a manner that bonding of molecules to the molecule coupling layer causes a change in the oscillation behavior of the oscillation element.
