Silicon micro heater based tagging module and the biocompatible packaging for capsule endoscope

Capsule endoscopes are widely used in gastro intestinal tract imaging. Current devices lack ways to precisely mark locations of interests during the image diagnose process. This paper presents a low-power micro heater module based on silicon technology, which can be integrated inside a capsule endoscope for precise localization. A custom polycarbonate capsule package is developed for both the tagging module and the capsule electronics. The complete system is then encapsulated with parylene thin film for biocompatibility purpose, which is analyzed in this study.
