Publication number: 20110095654Abstract: An apparatus couples mechanical energy in the form of wide-range mechanical vibrations to a piezo sensor, especially a multi-layer piezo sensor, for converting the mechanical energy into electric energy. The apparatus has a housing onto which the mechanical energy acts in the form of the vibrations, and a vibrating mass provided within the housing. The vibrating mass is clamped with at least two piezo sensor units in the housing. An apparatus thus adapts a piezo sensor energy converter for a wide range of frequencies and amplitudes of mechanical vibrations.Type: ApplicationFiled: May 12, 2009Publication date: April 28, 2011Applicant: Siemens AktiengesellschaftInventors: Thorsten Steinkopff, Andreas Wolff

Publication number: 20100133957Abstract: The invention relates to a high-lifting capacity piezoelectric actuator (1) comprising an piezoelectric layer (10) and a second layer (20) whose material gradient is directed to the thickness. An electric field produces different extension degrees in said piezoelectric layer (10) and in the second layer (30), thereby increasing the lifting capacity of the piezoelectric actuator (1) in combination with an impressed mechanical prestressing. The inventive piezoelectric actuator is used at a low voltage, for example, for bio and medical engineering (micropumps, microvalves), in industrial electronic engineering (pneumatic valves) and for microactuators and micromotors.Type: ApplicationFiled: June 12, 2006Publication date: June 3, 2010Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Carsten Schuh, Thorsten Steinkopff, Andreas Wolff

Patent number: 7336022Abstract: Piezoelectrical bending converter with at least one monolithic layered composite, includes a piezoelectric-active ceramic layer with a lateral dimension change which may be generated by application of an electrical field and at least one further piezoelectric-active ceramic layer with a further lateral dimension change, different from the lateral dimension change. An electrode layer is arranged between the ceramic layers, for generation of the electric fields. The layered composite preferably comprises several piezoelectric-active layers and electrode layers arranged between the above. The shift is thus obtained as a gradient of the dimension changes in the direction of the stack of the layered composite. The dimension changes for the ceramic layers and the gradient may be adjusted by the generation of the electrical fields. In order to achieve a shift it is necessary not to have a piezoelectric-inactive layer.Type: GrantFiled: June 14, 2002Date of Patent: February 26, 2008Assignee: Siemens AktiengesellschaftInventors: Carsten Schuh, Thorsten Steinkopff, Andreas Wolff

Patent number: 7015629Abstract: An additional contacting (30) for a piezoelectric component (10) is formed as a multilayer structure, wherein the piezoelectric component (10) is formed by a stack (16) of alternatingly arranged piezoelectric ceramic layers (11) and electrode layers (12, 13). The additional contacting (30) has a series of connecting elements (31) for connecting a metallization (15) of the electric component (10) to an electrical connecting element (19). In order to minimize mechanical loads during dynamic operation of the piezoelectric component (10), the additional contacting (30) is configured as an individual, structured component (32), especially in the form of a structured foil. Said structured foil (32) advantageously has a current conduction path (33) which is common to the connecting elements (31) and a contacting zone formed in the area of static base plate (17), wherein the additional contacting (30) is connected to the electrical connecting element in the area of said contacting zone.Type: GrantFiled: October 29, 2003Date of Patent: March 21, 2006Assignee: Siemens AktiengesellschaftInventors: Karl Lubitz, Carsten Schuh, Thorsten Steinkopff, Andreas Wolff

Patent number: 6462462Abstract: A product comprised of a non-linear piezoelectric materia, in which a plurality of reference points are defined. The product is exposed to a distribution of an electrical field and is characterized by a distribution of characteristic linear moduli over the reference points, whereby each modulus is determined as an increase in a secant reaching, in an associated characteristic curve, from a zero point up to a point corresponding to the reference point. The characteristic curve is projected from a system of characteristic curves that describes relations between the electrical field and loadings characteristic of additional state quantities in the material. In addition, the invention relates to a method for determining a corresponding distribution of characteristic moduli in a corresponding product.Type: GrantFiled: March 9, 1999Date of Patent: October 8, 2002Assignee: Siemens Aktiengesellschaft AGInventor: Thorsten Steinkopff
