NFI is based on a proprietary topology/ imaging technology. The sensor layout is a piece of glass coated with an Indium Tin Oxide (ITO) pattern on the front side and complete ITO coating on the back side. The front of the sensor is optically laminated to a layer of passive glass, typically .043” thick.
An excitation waveform is supplied to the conductive sensor and generates an electrostatic field which becomes the baseline. When a finger or other conductive stylus comes into contact with the sensor, a
change occurs in the electrostatic field. The control electronics then subtract the change from the baseline and determine the peak imaging shape and location to establish the x- and y-axis coordinates of the touch location.
