Abstract
A pressure sensor has a substrate and a transistor structure. The substrate has a cavity formed in the substrate. The transistor structure is arranged above the cavity. The transistor structure has a flexible heterostructure and at least one source contact, drain contact, and gate contact each connected to the heterostructure in an electrically conductive manner. The heterostructure is configured to assume a position corresponding to a pressure ratio between a first pressure in the cavity and a second pressure on a side of the heterostructure opposite the cavity. The transistor structure is configured to provide an electrical signal corresponding to the position.
