Abstract: A sensor and a method for measuring a pressure are disclosed. In an embodiment the sensor includes a main body including a piezoelectric material and at least two internal electrodes arranged in the piezoelectric material, wherein the at least two internal electrodes are arranged in such a way that a voltage arises between the at least two internal electrodes when a pressure acts on a side surface of the main body that is provided for an application of pressure.

Abstract: A pressure sensor and a method for measuring a pressure are disclosed. In an embodiment the pressure sensor includes a main body comprising a piezoelectric material and at least two internal electrodes arranged in the piezoelectric material, wherein the at least two internal electrodes are arranged such that a voltage arises between the at least two internal electrodes when a pressure acts on a side surface of the main body that is provided for an application of pressure.
