Abstract
(DE)
Die Erfindung betrifft einen Kraftsensor auf der Basis eines auf einem Substrat (1; 11) aufgebrachten organischen Feldeffekttransistors (10), bei dem eine auf den Transistor einwirkende mechanische Kraft eine dieser Kraft entsprechende Änderung seiner Source-Drain-Spannung oder seines Source-Drain-Stroms (ID) verursacht, die jeweils als Messgröße (Vmess, Imess) für die einwirkende Kraft erfassbar sind, einen einen derartigen Kraftsensor verwendenden membranbasierten Drucksensor, einen eine Vielzahl derartiger Kraftsensoren verwendenden ein- oder zweidimensionalen Positionssensor und einen eine Vielzahl solcher Kraftsensoren verwendenden Fingerabdrucksensor.
(EN)
The invention relates to a force sensor based on an organic field effect transistor (10) that is applied to a substrate (1; 11). According to the invention, a mechanical force that acts on the transistor causes a corresponding modification of the source-drain voltage or the source-drain current (ID), whereby said modification can be respectively detected as a measured variable (Vmess, Imess) for the exerted force. The invention also relates to a membrane-based pressure sensor that uses a force sensor of this type, to a one- or two-dimensional position sensor that uses a plurality of force sensors of this type and to a fingerprint sensor that uses a plurality of force sensors of this type.
(FR)
L'invention concerne un capteur de force réalisé sur la base d'un transistor à effet de champ organique (10) appliqué sur un substrat (1; 11). Selon l'invention, une force mécanique appliquée sur le transistor provoque une variation correspondante de la tension source-drain ou du courant source-drain (ID) du transistor, pouvant être détectée en tant que grandeur de mesure (Vmess, Imess) caractérisant la force appliquée. L'invention concerne également un capteur de pression à membrane faisant intervenir un tel capteur de mesure, un capteur de position monodimensionnel ou bidimensionnel faisant intervenir une pluralité de tels capteurs de force, et un capteur d'empreintes digitales faisant intervenir une pluralité de tels capteurs de force.
