摘要： A method and apparatus for electrical detection of a finger print has a reduced number of interconnect signals between a sensor area and a substrate and an electronic circuit for excitation and detection of the finger print compared to a single-chip finger print sensor. The individual signals are connected internally at the sensor substrate in such a way that the response from the individual sensor elements can be separated from each other. Cross-talk is reduced by keeping the sensor outputs at a constant potential, thus eliminating the effect of capacitive coupling between different sensor outputs and also between sensor outputs and a ground or reference potential.

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.
