Active vibration damping system for protection of printed circuit board, uses piezo electric sensors and actuators

Device and method for the excitation and/or damping and/or detection or structural oscillations of a plate-shaped device using a piezoelectric strip device

Corrosion protection for micromechanical sensor elements, e.g. for a pressure sensor, comprises a passivating agent that at least partially covers electrical components and a material layer applied to the top of the passivator

Damping device for structural vibrations of carrier device, has piezoelectric actuator device, where surface of carrier device is connected with one of two end areas, to transfer lengthwise or transverse vibrations to carrier device

Apparatus and method for the excitation and/or damping and/or detection of structural oscillations of a plate-shaped device by means of a piezoelectric strip device

Sensing surface element for determining object lying on surface element by force or weight, comprises flexible layer material, and multiple touch-sensitive sensors, which have electrical measuring characteristic

Pump device for conveying e.g. oil, has pump elements fastened at carrier elements, where portions of pump elements are actively cooperate with each other such that volume, which is guided from portions, is promoted to medium of portions

Surface element for sensing floor covering of e.g. living room, to supervise e.g. elder people, has region comprising sensor elements to output measurement signal, which provides two states and operation of sensor element for display
