Sintered tantalum electrodes coated with tantalum pentoxide films can perform stably as anodes when implanted into biological tissues, and probably always do. Capacitances and leakages do not differ much from those obtained in conventional electrolytes. Such electrodes should be useful for implanted stimulators where space is short.
