摘要： A fingerprint sensor for incorporation into a smart card includes sensor electrodes for detecting fingerprint features of a finger placed on a contact surface, the sensor electrodes being disposed above a substrate layer that comprises a first portion, a second portion, and a ledge where an edge of the first portion extends beyond an edge of the second portion. Contact points disposed on the ledge connect the fingerprint sensor to electrical conductors of an intermediate layer of a multi-layer smartcard. The fingerprint sensor is disposed within a cavity formed in a body of the smartcard, and the contact points disposed on the ledge are set at a depth corresponding to the thickness of an outer layer covering the electrical conductors of the intermediate layer of the smartcard.

摘要： The invention relates to a sensor for detection of properties and structures of an organic tissue and its surface, e.g., a fingerprint sensor comprising a chosen number of sensor electrodes at chosen positions for coupling to a finger tissue and its surface having a size less or comparable to the size of the structures, characteristics or properties of the finger tissue or surface, and a processing unit including electronic circuitry connected to said electrodes for detection of the voltage at, or the current flow in the electrodes, thereby providing for detection and collection of information of related capacitance, impedance, electromagnetic field, fingerprint, tissue aliveness or other biometric, physical, physiological, thermal or optical or characteristics or properties of the tissue or its surface positioned over the electrodes, the processing unit being mounted on one side of a substrate and the electrodes being embedded in said substrate, the substrate including through going first, second and third conductive paths between said sensor electrodes and said measurement circuitry. The substrate is made from a polymer material such as Polyimide, implemented as a rigid or a flexible multi layer build-up substrate, said first, second, and third conductive paths are constituted by through going substrate sections of a chosen size and material.

摘要： An electronic sensor forms a grid to detect surface features of a proximally located object, such as a fingerprint. The grid includes a plurality of parallel drive lines connectable to a drive source and a plurality of parallel pickup lines oriented substantially perpendicular to the drive lines and overlapping the drive lines. The drive lines are separated from the pickup lines by an insulating dielectric layer. The overlaps where the drive lines and pickup lines cross define impedance-sensitive electrode pairs which act as pixels at which surface features of the proximally located object are detected. One or more conductive probes extend from one or more corresponding impedance-sensitive electrode pairs, through an overlay layer of insulating material, to the sensing surface.

摘要： A sensor unit for measuring surface structures and properties of an object of organic tissue includes a contact surface adapted to have mechanical contact with the object, a first dielectric layer made from a dielectric material, a first conductor layer including at least one shielding electrode essentially covering an area of the dielectric layer facing the contact surface, the at least one shielding electrode surrounding at least one essentially non-conductive aperture defining a sensing region, and a second conductor layer separated from the first conductor layer by the first dielectric layer and comprising a number of conductive wires extending at least partially under the at least one aperture and having a direction essentially perpendicular to the sensing region, each wire having a predetermined width. A sensing area of each wire is defined by the width and the length of each wire extending in the sensing region.
