Claims (5)
1. Fremgangsmåde til at konvertere akustiske bølger til spændingsoutput, som skal anvendes til at stimulere hørenerven i et cochlea-implantat, hvor hver spændingsoutput svarer til et bestemt frekvensbånd af de indkommende akustiske bølger; hvor cochlea-implantatet omfatter en transducer (4) og en cochlea-elektrode (3) som forbinder transduceren (4) med hørenerven, hvor transduceren (4) består af - mindst en base (5) fastgjort til et vibrationselement af høresystemet som vibrerer under indflydelsen af de indkommende akustiske bølger, - en gruppe af cantilever-bjælker (6) hver med en fri ende (6a) og en fastgjort ende (6b) fastgjort til basen (5), og hver med en forudbestemt egenfrekvens, - et piezoelektrisk stykke (7) forbundet til hver af cantilever-bjælkerne (6) og - mindst en optagerelektrode (8) associeret med hver cantilever-bjælke (6) for at optage spændingen produceret af de piezoelektrisk stykker (7) og forbundet til cochlea-elektroden (3) for at sende spændingen til cochlea-elektroden (3) og fremgangsmåden til at konvertere akustiske bølger til spændingsoutput omfatter trinnene - at udsætte cantilever-bjælkerne (6) for vibrationer produceret på vibrationselementet af høresystemet under indflydelsen af de indkommende akustiske bølger og - at generere spændingsoutput grundet piezoelektricitet, ved de piezoelektrisk stykker (7) associeret med hver vibrerende cantilever-bjælke (6) kendetegnet ved at hver af de piezoelektriske stykker (7) er forbundet på overfladen afen cantilever-bjælke (6) og nær den fastgjorte ende (6b) således at de piezoelektriske stykker (7) oplever den maksimalt mulige belastning hvor spændingsoutputtene, genereret af de piezoelektrisk stykker (7) associeret med hver cantilever-bjælke (6) vibrerende nær dets egenfrekvens, er højere end en tærskelspændingsværdi som er tærskelspændingsværdien krævet til at stimulere hørenerven og ved at de forudbestemte egenfrekvenser af cantilever-bjælkerne (6) svarer til frekvenserne som en patient ikke er i stand til at opfatte.
2. Fremgangsmåden ifølge krav 1, hvor mindst en af cantilever-bjælkerne (6) inkorporerer en spidsmasse (9) til forudbestemmelse af egenfrekvensen.
3. Fremgangsmåden ifølge et hvilket som helst af de ovenstående krav, hvor transduceren (4) omfatter flere baser (5) med bjælker (6) af forskellige egenfrekvenser, forbundet oven på hinanden og dannende lag.
4. Fremgangsmåden ifølge et hvilket som helst af de ovenstående krav, hvor antallet af cantilever-bjælker (6) ligger i området fra 1 til 30.
5. Fremgangsmåden ifølge et hvilket som helst af de ovenstående krav, hvor transduceren (4) yderligere omfatter en biokompatibel coating.
