Abstract

The present invention provides a gastrointestinal tract positioning switch, a method of manufacturing the gastrointestinal tract positioning switch and a site-specific delivery capsule. The gastrointestinal tract positioning switch includes a base, a first electrode, a second electrode, a conductive device and a positioning film. The first electrode and the second electrode are spaced apart from each other and fixed on the base. The first electrode and the second electrode electrically connected to the conductive device respectively, and covered by the positioning film. Both the first electrode and the second electrode are an inert electrode, and can be exposed after dissolution or/and degradation of the positioning film in the stomach or intestine.
