Abstract

Et sensorsystem omfatter en implanterbar sensor (11) og en brukeranordning forbundet med denne. En sensitiv væske er innesluttet i sensoren (11), som glukose kan penetrere inn i. Viskositeten av blandingen som består av den sensitive væske og glukose, måles. Brukeranordningen, som styrer målingen og dens bedømmelse, består av en bærbar anordning som bæres eksternt på huden. Viskositeten måles på grunnlag av rotasjonen av et måleelement (35) som er plassert i sensoren (1') og som kan drives av en drivmagnet (24), som likeledes er plassert i sensoren (1'). Rotasjonen av måleelementet (35) analyseres på grunnlag av dets sinkebeteende etter avskruing av drivmagneten (24). I en annen utførelse måles viskositeten på grunnlag av oscillasjonsbeteendet av et oscillasjonselement som er plassert i sensoren og som kan eksiteres til å oscillere av en magnet som likeledes er plassert i sensoren. Oscillasjonsbeteendet analyseres på grunnlag av sinkebeteendet av oscillasjonselementet etter avskruing av magneten.
