Ingestible wireless capsules for enhanced diagnostic inspection of gastrointestinal tract

Mahdi RASOULI, Andy Prima KENCANA, Van An HUYNH, Eng Kiat TING, Joshua Chong Yue LAI, Kai Juan WONG, Su Lim TAN, Soo Jay PHEE

Frontiers of Mechanical Engineering 2011, Volume 6, Issue 1,   Pages 40-44 doi: 10.1007/s11465-011-0204-4

Abstract:

Wireless capsule endoscopy has become a common procedure for diagnostic inspection of gastrointestinal tract. This method offers a less-invasive alternative to traditional endoscopy by eliminating uncomfortable procedures of the traditional endoscopy. Moreover, it provides the opportunity for exploring inaccessible areas of the small intestine. Current capsule endoscopes, however, move by peristalsis and are not capable of detailed and on-demand inspection of desired locations. Here, we propose and develop two wireless endoscopes with maneuverable vision systems to enhance diagnosis of gastrointestinal disorders. The vision systems in these capsules are equipped with mechanical actuators to adjust the position of the camera. This may help to cover larger areas of the digestive tract and investigate desired locations. The preliminary experimental results showed that the developed platform could successfully communicate with the external control unit via human body and adjust the position of camera to limited degrees.

Thermo-fluidic devices and materials inspired from mass and energy transport phenomena in biological system

Jian XIAO , Jing LIU ,

Frontiers in Energy 2009, Volume 3, Issue 1,   Pages 47-59 doi: 10.1007/s11708-008-0068-4

Abstract: Mass and energy transport consists of one of the most significant physiological processes in nature, which guarantees many amazing biological phenomena and activities. Borrowing such idea, many state-of-the-art thermo-fluidic devices and materials such as artificial kidneys, carrier erythrocyte, blood substitutes and so on have been successfully invented. Besides, new emerging technologies are still being developed. This paper is dedicated to presenting a relatively complete review of the typical devices and materials in clinical use inspired by biological mass and energy transport mechanisms. Particularly, these artificial thermo-fluidic devices and materials will be categorized into organ transplantation, drug delivery, nutrient transport, micro operation, and power supply. Potential approaches for innovating conventional technologies were discussed, corresponding biological phenomena and physical mechanisms were interpreted, future promising mass-and-energy-transport-based bionic devices were suggested, and prospects along this direction were pointed out. It is expected that many artificial devices based on biological mass and energy transport principle will appear to better improve various fields related to human life in the near future.
