System and method for manufacturing a swallowable sensor device
Methods and systems for manufacturing a swallowable sensor device are disclosed. Such a method includes mechanically coupling a plurality of internal components, wherein the plurality of internal components includes a printed circuit board having a plurality of projections extending radially outward. A cavity is filled with a potting material, and the mechanically coupled components are inserted into the cavity. The cavity may be pre-filled with the potting material, or may be filled after the mechanically coupled components have been inserted therein. A distal end of each projection abuts against a wall of the cavity thereby preventing the potting material from covering each distal end. The cavity is sealed with a cap causing the potting material to harden within the sealed cavity to form a housing of the swallowable sensor device, wherein the distal end of each projection is exposed to an external environment of the swallowable sensor device.
1. A method for manufacturing a swallowable sensor device, comprising:
mechanically coupling a plurality of internal components of the swallowable sensor device using a post; wherein the plurality of internal components includes a printed circuit (PC) board having a plurality of projections extending radially outward;
filling a cavity with a potting material;
inserting the mechanically coupled components into the cavity, a distal end of each projection abutting against a side wall of the cavity thereby preventing, the potting material from covering the distal end of each projection; and
sealing the cavity with a cap, wherein the potting material hardens within the sealed cavity to form a housing of the swallowable sensor device such that the distal end of each projection is exposed to an external environment of the swallowable sensor device.
2. The method of claim 1 , wherein the cavity is filled with the potting material before inserting the mechanically coupled components therein.
3. The method of claim 1 , wherein the cavity is filled with the potting material after inserting the mechanically coupled components therein.
4. The method of claim 1 , wherein a first end of the post abuts against a base of the cavity and a second end of the post abuts against the cap thereby preventing the potting material from covering the first and second ends of the post.
5. The method of claim 4 , further comprising:
providing a voltage between the first and second ends of the post to test operability of the swallowable sensor device.
6. The method of claim 1 , wherein the post is electrically coupled to the PC board.
7. The method of claim 1 , wherein the post comprises a transducer configured to convert electrical energy to mechanical energy.
8. The method of claim 1 , wherein the plurality of internal components are annularly-shaped and mechanically coupled by the post along a common central axis.
9. The method of claim 1 , wherein at least one of the plurality of projections comprises an electrode, and the method further comprises electrically coupling a sensor to the electrode.
10. The method of claim 1 , wherein at least one of the plurality of projections comprises a hollow tubing coupled to a container included inside the housing of the swallowable sensor device.
11. The method of claim 1 , wherein the plurality of internal components includes a battery.
12. The method of claim 1 , wherein the plurality of internal components includes a transducer that is configured to convert electrical energy to mechanical energy.
