Abstract | |||||||
| WO 2009049613 A2 UPAB: 20090514 NOVELTY - The element has a sintered piezoelectric or electrostrictive component (2) completely surrounded by a low temperature co-fired ceramic (LTCC), where the electrostrictive component is contacted with the element in an electrically conductive manner. The electrostrictive component is designed as plate shape or as molded body, and is formed with piezo-ceramic fiber or electrostrictive fiber/small rod. The electrostrictive component is arranged asymmetric with respect to an axis of the element within the co-fired ceramic. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing an operative actuating and/or sensing element. USE - Operative actuating and/or sensing element for use as a pump, dosing device, valve, force sensor, path sensor, pressure sensor, actuator or ultrasonic transducer in a metal component or a structure component from metal, glass, plastic or a component with fiber composite material (all claimed). ADVANTAGE - The sintered piezoelectric/electrostrictive component is surrounded by the low temperature co-fired ceramic and is in contact with the operative actuating and/or sensing element in electrically conductive manner, thus inserting the element in integrated form into the interior of the components even under increased loads. | |||||||
