An attempt is being made to develop long-term stability in oxygen sensing electrodes. Suitable designs of such electrodes would then be made for long-term insertion or implantation in tissue to chronically monitor oxygen tension. By employing techniques of pretreatment and periodic anodization to a bare-tipped electrode in saline, repeatable electrode operating characteristics have been obtained for over six days. Investigations to obtain this type of response in biological media and in vivo conditions is being attempted, using a semipermeable membrane coating on the electrode tips to ward off poisoning. A long-term in vivo electrode implantation package has been developed for use in the in vivo oxygen electrode tests. Good oxygen response has been obtained for over 30 days with this system. Author
