Abstract

A fingerprint sensor defined by an array of switches including, each switch (1) comprising first and second contact portions (3, 6) separated by a gap, and a bridge member defined by a portion of a continuously conductive film for connecting the first and second portions across the gap (9). One of the contact portions is defined by a contact pad (6) and the length of the gap in the direction substantially parallel to the adjacent edges of the first and second contact portions is greater than the width of the gap between the first and second contact portions.
