Abstract
(A1) Gegenstand der Erfindung ist ein Taktilsensor (T) mit einer Sensorzelle (S1, S2, S3, S4), wobei eine Sensorzelle durch eine Kontaktflaeche (11, 12, 21, 22) zwischen einem ersten (1, 1') und einem zweiten (2, 2') elektrisch leitfaehigen Werkstueck gebildet ist, wobei mindestens ein elektrisch leitfaehiges Werkstueck aus flexiblem Material besteht und an der Kontaktflaeche ein messbarer Uebergangswiderstand vorliegt, welcher sich unter mechanischer Belastung aendert. Der Taktilsensor (T) ist dadurch gekennzeichnet, dass er ein Sensorzellenarray mit mindestens zwei voneinander beabstandeten Sensorzellen aufweist, wobei zwei benachbarte Sensorzellen ein gemeinsames erstes oder zweites elektrisch leitfaehiges Werkstueck (1, 1', 2, 2') aufweisen und jeweils mindestens eine Oberflaeche der elektrisch leitfaehigen Werkstuecke mit mindestens einem Traeger (30, 31, 32, 34) verbunden ist.

DE 102007022872 A1 UPAB: 20081205 NOVELTY - The tactile sensor (T) has a sensor cell (S1,S2,S3,S4), which is formed by a contact surface (11,12,21,22) between two electrically conductive work pieces. The electrically conductive work pieces consist of flexible material. Two sensor cells are present at a distance from each other. Two neighboring sensor cells are provided, which have a common former or latter electrically conductive work piece. A surface of every electrically conductive work pieces is connected with a carrier (30). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) an input device (2) a robot. USE - Tactile sensor for measuring pressure distributions. ADVANTAGE - The tactile sensor has two sensor cells, which are present at a distance from each other, and two neighboring sensor cells have a common former or latter electrically conductive work piece, and hence ensures that the tactile sensor is manufactured in a simple manner.
