Abstract

Denne oppfinnelsen angår en sensormodul for måling av strukturer i en overflate, særlig en fingeroverflate, som beveges over sensormodulen, omfattende et antall sensorelementer og en ytre elektrode plassert ved siden av sensorelementene, der sensorelementene er er koblet til minst en AC driverkrets som påtrykker en varierende strøm eller spenning, for derved å koble et signal gjennom sensorelementene til den ytre elektroden. Sensorelementene er også koblet til en elektronisk krets plassert på et substrat, hvilket substrat omfatter leder som kobler sensorelementene til den elektroniske kretsen, og der den elektroniske kretsen er innrettet til å måle størrelsen til kapasitansen eller AC impedansen mellom hvert sensorelement og den ytre elektroden. Sensorelementene utgjør et i det vesentlige lineært array, der arrayet er innrettet til å måle kapasitansen eller impedansen mellom hvert sensorelement og den ytre elektroden ved valgte tidspunkter, og at de målte verdiene blir kombinert for å danne en representasjon av overflatemønsteret.
