要約
(EN)
The invention discloses a multilayer tactile sensor. In particular, a sensor assembly comprising first, second and third layers of flexible material forming, when superposed, a pressure-sensitive sensor having at least two sensor cells. The first layer comprises first and second electrically conductive regions mechanically connected to each other via an electrically non-conductive region. The second layer comprises a third electrically conductive region. The third electrically conductive region of the second layer overlaps the first and second electrically conductive regions of the first layer. The region of overlap defines an active region of a first and a second sensor cell. The third layer is formed of a conductive elastic material that cooperates under a local mechanical load in the active region with the first and second conductive regions of the first layer so that an electrical resistance between the electrical conductive regions changes in the place of the compressive load. Furthermore, the sensor assembly comprises a fixation adapted to fix the first and the second layers together. The fixation is arranged outside the active region so that the first and third layers lie unloaded on top of each other in the active region and the surfaces of the first and third layers facing each other are substantially free of a fixation.

公开了多层触觉传感器。具体地,传感器组件包括叠加时形成有至少两个传感器单元的压敏传感器的柔性材料的第一、第二和第三层。第一层包括经非导电区域机械连接一起的第一和第二导电区域。第二层包括在表面延伸的第三导电区域。第三导电区域与第一和第二导电区域交叠,交叠区域限定第一和第二传感器单元的有效区域。第三层由导电弹性材料形成,其在有效区域中的局部机械荷载下与第一层的第一和第二导电区域结合,使电阻在第一、第二和第三电区域之间在压力荷载位置处改变。传感器组件还包括将第一和第二层固定一起的固定物,固定物布置在有效区域的外部,使在有效区域中第一和第三层无荷载地位于彼此顶部且第一和第三层的彼此面对表面基本免于固定。
