Endoscopy is a medical procedure carrying out in-vivo tests. The conventional wired endoscopy process is pain staking and time consuming. An alternative to this wired one would be a wireless endoscope system. Various pill type endoscopes such as iPill, Sayaka, and Smart Pill have been developed for drug delivery, imaging, and pH sensing in the stomach and intestines. The current device size of approximately 10 mm × 20 mm allows the usage of products only for a human adult as the average diameter of adult upper esophagus of approximately 13 mm is large enough to accommodate such devices while they are too big for children. To extend the usage of such wireless endoscopy to pediatric applications, pill should be greatly reduced in size. For instance, a standard small `Size 1' capsule with a dimension of 6.91 mm × 19.4 mm would be appropriate.
