Capacitive Sensor Element and Method for the Production Thereof

摘要

The invention relates to a capacitive sensor element with a plurality of sensor fields, as they correspond for example to the arrangement on a touch screen. This capacitive sensor element comprises at least one multilayer body made up of two structured electrically conductive layers and an insulating layer in between. The invention provides a layout with redundant conductive strips for an arrangement of crossing conductive strips, through which the requirement for register accuracy in the two-layer lamination of layer electrodes is reduced, in particular with respect to connecting the connections to the plugs in the edge area of a module using a corresponding sensor element.

1. A capacitive sensor element comprising at least one multilayer body made up of two structured electrically conductive layers and an insulating layer in between,
wherein the structuring of an electrically conductive first and second layer comprises conductive strips, in each case galvanically separated from each other, only some of which conductive strips of the first or second layer are connected to connections, and conductive pads connect at least some of the conductive strips to the connections, with the result that the connections of the first and second electrically conductive layers lie in one plane and the insulating layer does not separate the two structured electrically conductive layers from each other over the whole surface.
