Definitions

  • An object of the invention is to reduce the problems of masking and orthogonality at the contact points on the sensor without necessarily implementing additional electronic processing.
  • the conductive tracks of the upper layer advantageously consist of transparent conductive oxide (for example indium tin oxide ITO).
  • transparent conductive oxide for example indium tin oxide ITO.
  • those of the lower layer are also advantageously constituted by transparent conductive oxide (for example indium tin oxide ITO).
  • FIG. 1 represents a view from above of the arrangement of the rows and columns of conductive tracks of a multicontact tactile sensor of the prior art
  • the multicontact touch sensor 1 described here is preferably transparent, but it is understood that the invention is also applicable to a sensor 1 not transparent, thus comprising at least one non-transparent layer.
  • the sensor 1 always comprises an upper layer 2 provided with conducting track lines 3, a lower layer 4 provided with conductive track columns 5 and spacing spacers 8 arranged in areas where these tracks 3 and 5 are not susceptible of to form an intersection during a contact.
