Title: The Innovative Contributions of Hans Hellebrand in Piezoelectric Technology
Introduction
Hans Hellebrand, a notable inventor based in München, Germany, has made significant strides in the field of piezoelectric technology. His work is characterized by a relentless pursuit of innovation, which is reflected in his four patents. Hellebrand continues to push the boundaries of engineering at Siemens Aktiengesellschaft, where he translates theory into practical applications.
Latest Patents
One of Hellebrand's most recent inventions is the "Method for producing a monolithic multilayer piezo actuator." This groundbreaking method allows for the manufacturing of a monolithic piezoelectric actuator of multilayer design with a high aspect ratio. The process involves alternately layering green piezoceramic films and electrode material, and compressing these layers while elevating temperatures to remove binders, forming a composite. By stacking multiple composites and sintering them, Hellebrand's design achieves enhanced mechanical strength and superior piezoelectric properties.
Another notable patent is the "Piezoelectric actuator with a new type of contacting and a method for the production thereof." This innovation introduces electrically conductive contact tabs strategically applied to metallization strips, designed to mitigate the effects of cracks. Should cracks occur, they are directed to run along the projecting region of the contact tab, maintaining electrical connectivity.
