A method of making an integrated texture sensor for sensing a texture is
described. In one embodiment, the method is directed to a sensor that
that is protected from external contaminating particulates and will
self-equalize using air from outside the sensor. Further combinations of
such protection among various membrane switches, in combination with
various types of membranes, is described. In another embodiment, a method
of making a skin-texture sensor for sensing a skin texture having a
plurality of ridges and a plurality of valleys is described, such that
when completed, applying a ridge of the texture to a membrane switch will
cause flexure of the membrane resulting in a contact between the lower
electrode and the upper electrode, the contact establishing an electrical
communication between said one of the row lines and said one of the
column lines, whereas disposing a valley of the texture over said each
membrane switch will not result in the contact between the lower
electrode and the upper electrode.
