Abstract
A sensing surface is presented for use in monitoring a three dimensional behavior of one or more objects above the surface. The sensing surface is associated with a self-capacitance sensor and comprises a plurality of self-capacitive sensing pads located on a single layer. The sensing surface is configured for providing measured data indicative of a three-dimensional behavior of one or more objects over an active area of the sensing surface. The pattern of the pads is configured such that each sensing pad can be connected to an edge of the sensing surface on said single layer. The technique further enables the use of a capacitive sensor comprising the sensing surface.
