Abstract

En avfølingsanordning og fremgangsmåte. Anordningen irmbefatter et første element og et andre element. Hvert av elementene irmbefatter en første elekfrode og en andre elekfrode, og et piezoelektrisk lag meUom og forbundet med nevnte første og andre elekfrode. Den første elekfroden, den andre elekfroden og det piezoelektriske laget i hvert element darmer en trykkbølgefransducer. Nevnte første og andre elementer orienteres slik at den andre elekfroden i det første elementet vender mot den andre elekfroden i det andre elementet. Elementene er forflyttet fra hverandre, slik at nevnte andre elekttoder darmer platene i en kondensator.
