Patent number: 10031034Abstract: A method, a device and use for measurement of a force with a pressure sensor made of a piezoelectric material. The change in the capacitance of the pressure sensor is used for force measurement so that no load amplifier is necessary for measurement and as a result the measuring system as a whole is miniaturized.Type: GrantFiled: August 18, 2014Date of Patent: July 24, 2018Assignee: CeramTec GmbHInventors: Reiner Bindig, Tobias Schmidt, Hans-Jürgen Schreiner

Patent number: 9598319Abstract: According to the state of the art, piezoceramic multi-layer elements are sintered in air at temperatures of approximately 1100 DEG C or higher. Therefore, only a noble metal having a high melting temperature can be used as the inner electrode. Non-noble metals would oxidize. Therefore, a silver-palladium alloy having up to 40% palladium is normally used. However, such a measure is associated with high material costs. Lower melting temperatures of the inner electrode material, however, also require a ceramic material having correspondingly low sintering temperatures. The invention therefore proposes that an electrically non-conductive sintering additive added be added to the base material, and that the inner electrode comprise silver, preferably pure silver, as the main material component thereof, and an electrically non-conductive material component and/or a metal alloy or metal oxide mixture.Type: GrantFiled: October 20, 2008Date of Patent: March 21, 2017Assignee: CeramTec GmbHInventors: Reiner Bindig, Hans-Jurgen Schreiner

Publication number: 20170052530Abstract: The invention relates to a method for monitoring a machining tool that is used for machining primarily metal materials, comprising a cutting tool, wherein the cutting force, feed force, and passive force can be adjusted during machining, and comprising sensors to measure forces. In order that machining can be stopped 2 to 60 seconds, preferably 2 to 10 seconds, prior to failure of the cutting body, the invention proposes that the sensors continuously sense at least one of said forces during machining and machining is stopped if a sudden reduction in the sensed force occurs.Type: ApplicationFiled: December 3, 2014Publication date: February 23, 2017Inventors: Jose AGUSTIN-PAYA, Hans-Jurgen SCHREINER, Reiner BINDIG

Patent number: 9478726Abstract: The invention relates to actuator module (22) having a piezoceramic multilayer actuator (1) arranged in a casing (23). In order to avoid an increase in conductivity and hence rising leakage current at the actuator surface even after a long period of use, the invention proposes that the casing (23) is hermetically sealed, and a chamber (24) is arranged between the multilayer actuator (1) and the casing (23), which chamber is entirely or partially filled with a medium (21) that chemically transforms and/or binds water.Type: GrantFiled: January 10, 2013Date of Patent: October 25, 2016Assignee: CeramTec GmbHInventors: Reiner Bindig, Hans-Jürgen Schreiner

Patent number: 8823244Abstract: A monolithic multilayer actuator made of a sintered stack of thin films of piezoceramio with embedded metallic internal electrodes. All metallic internal electrodes of one polarity are electrically connected in parallel by way of a base metallization applied to the stack and wherein an external electrode is connected in an electrically conducting manner to the base metallization for electrical contacting purposes. In order to provide that the external electrode can be applied to the base metallization using simple and cost-effective means so that said electrode is expandable such that it dissipates the cracks arising from cracking energy in the actuator without the external electrode disconnecting in the process that are sintered together, the layer being applied onto the base metallization.Type: GrantFiled: November 19, 2009Date of Patent: September 2, 2014Assignee: CeramTec GmbHInventor: Reiner Bindig
