Title (EN) TACTILE SENSOR
(FR) CAPTEUR TACTILE
(JA) 触覚センサ
Abstract:
(EN) This tactile sensor (1) is provided with: a non-magnetic flexible layer (3) which is formed on a substrate (2); a magnetic flexible layer (4) which is formed to be supported by the non-magnetic flexible layer (3), and in which particles that are not magnetized and have a magnetic permeability higher than the magnetic permeability of the non-magnetic flexible layer (3) are dispersed; a coil (5) which is formed in the substrate (2), and the inductance of which changes in accordance with deformation of the particles due to the external force acting on the magnetic flexible layer (4); and an inductance measurement circuit (6) which measures the change of the inductance of the coil (5).
(FR) L'invention concerne un capteur tactile (1) qui est pourvu : d'une couche souple non magnétique (3) qui est formée sur un substrat (2); d'une couche souple magnétique (4) qui est formée pour être supportée par la couche souple non magnétique (3) et dans laquelle sont dispersées des particules qui ne sont pas magnétisées et ont une perméabilité magnétique supérieure à la perméabilité magnétique de la couche souple non magnétique (3); une bobine (5) qui est formée dans le substrat (2) et dont l'inductance varie en fonction de la déformation des particules en raison de la force externe agissant sur la couche souple magnétique (4); et un circuit de mesure d'inductance (6) qui mesure la variation de l'inductance de la bobine (5).
(JA) 触覚センサ(1)は、基板(2)上に形成された非磁性柔軟層(3)と、非磁性柔軟層(3)の透磁率よりも高い透磁率を有して磁化されていない粒子が分散され、非磁性柔軟層(3)により支持されるように形成された磁性柔軟層(4)と、基板(2)に形成されて、磁性柔軟層(4)に作用する外力による粒子の変位に基づいてインダクタンスが変化するコイル(5)と、コイル(5)のインダクタンスの変化を計測するインダクタンス計測回路(6)とを備える。
