Title: **Eckhard Quandt: Innovator in TMR Sensor Technology**

Introduction

Eckhard Quandt, an accomplished inventor based in Bonn, Germany, is known for his groundbreaking work in sensor technology. With one notable patent to his name, he has made significant contributions to the field of measurements and mechanical stress sensing.

Latest Patents

Eckhard Quandt's notable patent is for a TMR (Tunneling Magnetoresistance) sensor. This innovative sensor is designed to measure mechanical changes in length, specifically as a compressive and/or tensile stress sensor. The technology features a sandwich system consisting of two flat, superposed electrodes that are separated by a tunnel element, particularly an oxide barrier. A current flows between the electrodes and through the tunnel barrier, with one electrode composed of a magnetostrictive layer that responds to elongation. Remarkably, this design allows for relative changes in system resistance greater than 10% at room temperature during elongation, making it a highly effective tool for precise measurements.
