Abstract

Zur Erkennung von Münzen wird ein Sensor verwendet, der die Prägung analysiert. Hauptbestandteil des Sensors ist ein polymeres, elastisches Material 20, das piezoelektrische Eigenschaften zeigt. Durch Andruck der Prägeseite einer Mün­ ze an die sensorische Fläche 23 wird ein den Hoch- bzw. Tiefstellen der Prägung entsprechendes eletrisches Signal erzeugt, das in einer nachgeschalteten Auswerteelektronik eine Beurteilung der Münze zuläßt. A sensor is used to detect coins, who analyzes the imprint. The main component of the sensor is a polymeric, elastic material 20, the piezoelectric Shows properties. By pressing the embossed side of a coin to the sensory surface 23 is a high or Lowering of the embossing corresponding electrical signal generated in a downstream evaluation electronics allows an assessment of the coin.
