Abstract

Βιοαισθητήρας εμφυτεύσιμος υποδόρια ή ενδοσωματικά, που χαρακτηρίζεται από κλειστό κύκλωμα μικροροής με βαθμονομητικά υγρά, το οποίο επικοινωνεί με λογική αντίστροφης μικροδιάλυσης με εξωτερικό του λεγόμενου κυκλώματος, ανοικτό και σε επαφή με τους ιστούς και ενδοκυττάριο υγρό ηλεκτρόδιο εργασίας, για την αυτόματη βαθμονόμησή του. Ένα ή περισσότερα του ενός ηλεκτρόδια εργασίας μπορεί να είναι τοποθετημένα σε ανοιγόμενα κυτία από ΕΑΡ, και να ανοίγουν για όσο διάστημα μετρούν, και να κλείνουν αμέσως μετά, το ένα να διαδέχεται το προηγούμενο στην μέτρηση, μετά την πτώση της ακρίβειάς του.
