Abstract:
1. An electronic device with a micro-electromechanical switch, comprising: a piezoelectric element with a piezoelectric layer located between a first and a second electrode layer with at least one electrode being located in each of said electrode layers, a first and a second MEMS electrode said first MEMS electrode being located on a surface of the piezoelectric element and said second MEMS electrode being located on the surface of a substrate so that the first MEMS electrode moves away from and/or towards the second MEMS electrode under the application of an actuating voltage to the piezoelectric element, and wherein at least one of the electrode layers is structured into electrodes while defining a displacement area in the piezoelectric element in which displacement area the first MEMS electrode is located and which displacement area is, under the application of different actuating voltages to different ones of the electrodes, configured to displace away from and/or towards the substrate in relation to the rest of the piezoelectric element.
