Spherical versus Capsule Shape Analysis for Wireless Endoscopy Applications

From our simulation experiments, we found that the spherical shaped endoscopic device has several advantages than the commercially used capsule shape for wireless endoscopic applications. Our results demonstrate that the velocity of sphere through the fluid is greater than that of the capsule shape through the same fluid. This means, the spherical shaped module excretes faster from the bowel and higher probability of easy exit from bowel after finishing examination. It is also found that the spherical has less pressure due to its geometry advantage than the capsule which has higher surface area and hence greater pressure in the laminar flow. From our findings, we suggest that the spherical shaped device is better substitute for the capsule shaped wireless endoscopic applications.
