Abstract

Denne oppfinnelsen angår en sensorinnretning for utførelse av målinger på en i det minste delvis ledende overflate, der sensoren omfatter et antall ledende strukturer ved eller direkte under overflaten, for eksempel et fingeravtrykk, hvilke ledende strukturer består av minst en stimulerings- eller strømmottakende elektrode og et antall sensorelementer koblet til avlesningselektrodene i en elektronisk krets for måling av impedans mellom elektrodene og nevnte minst en stimuleringselektrode, der sensorinnretningen også omfatter minst en bindende (eng: clamping) elektrode plassert nær sensorelementene og som er koblet til en valgt spenning. Avstanden mellom den bindende elektroden og sensorelementet er mindre enn avstanden mellom ryggene i et fingeravtrykk, fortrinnsvis i området 20-200 (jm.This invention relates to a sensor device for performing measurements on an at least partially conductive surface, wherein the sensor comprises a number of conductive structures at or directly below the surface, for example a fingerprint, which conductive structures consist of at least one stimulation or current receiving electrode and a number of sensor elements connected to the reading electrodes in an electronic circuit for measuring impedance between the electrodes and said at least one stimulation electrode, wherein the sensor device also comprises at least one binding (eng: clamping) electrode located near the sensor elements and which is connected to a selected voltage. The distance between the binding electrode and the sensor element is less than the distance between the ridges in a fingerprint, preferably in the range 20-200 (μm).
