Abstract:
In various embodiments, a sensor structure is provided. The sensor structure may include a first conductive layer; an electrode element; and a second conductive layer arranged on an opposite side of the electrode element from the first conductive layer. The first conductive layer and the second conductive layer may form a chamber. The pressure in the chamber may be lower than the pressure outside of the chamber.
