FINGERPRINT DIGITIZER WITH DEFORMABLE SUBSTRATE |
摘要 |
A method of producing an electrical circuit suitable for use as a fingerprint pattern digitizer. Conductive material is coated onto opposite sides of a plastics substrate from whence it is partially removed to define a pattern of conductive tracks. The opposite sides of the coated plastics device are connected by through vias coated with conductive material. The present invention in a further aspect provides a digitizing sensor comprising an array of individually actuable sensing cells on a deformable support.
