Electrostatic sensors
First Claim
1. A sensor comprising an array of electrostatic sensor elements, each capable of producing a respective output signal when the sensor is directed to a region of an object being sensed, the output signals being separately available at the sensor output to provide information relating to the electrostatic charge distribution across the region.

Abstract
A sensor 10 comprises an array of electrostatic sensor elements 12, each centred at a respective sensing position 14. Each element produces a respective output signal at 16. The outputs 16 can be used to drive respective pixels of a display. This allows an image to be created to represent the electrostatic charge distribution across the region to which the sensor is directed.
