Abstract

Dispositif de mesure de force sur une surface complexe La présente description concerne un dispositif de mesure de force conformable, destiné à être soumis simultanément à des forces en compression et des forces en flexion, le dispositif comprenant des capteurs (11, 12) disposés de part et d’autre d’un substrat (100), les capteurs comprenant une couche piézoélectrique organique (120) disposée entre une première électrode (110) et une deuxième électrode (130), les capteurs (11, 12) étant disposés en regard l’un de l’autre, de manière à former un bimorphe (10), les capteurs étant reliés à des pistes électriquement conductrices (200) destinées à être connectées à des appareils de mesure, les couches piézoélectriques organiques (120) des capteurs (11, 12) étant polarisées et les capteurs (11,12) étant destinés à être branchés électriquement aux appareils de mesure de manière à annuler soit les forces en compression soit les forces en flexion. Figure pour l'abrégé : Fig. 6Force Measurement Device on a Complex Surface This description relates to a conformable force measurement device intended to be subjected simultaneously to compressive and bending forces, the device comprising sensors (11, 12) arranged on either side of a substrate (100), the sensors comprising an organic piezoelectric layer (120) disposed between a first electrode (110) and a second electrode (130), the sensors (11, 12) being arranged opposite each other so as to form a bimorph (10), the sensors being connected to electrically conductive tracks (200) intended to be connected to measuring instruments, the organic piezoelectric layers (120) of the sensors (11, 12) being polarized and the sensors (11, 12) being intended to be electrically connected to the measuring instruments so as to cancel either the compressive or the bending forces.
