Wireless Endoscopy: Technology and Design

In this chapter we review the current capsule technology and the more conventional “gold standard” technologies against which the wireless devices are compared. Over the years there have been several implementations of capsule devices of growing sophistication as new technology has become available. A notable feature is the extent to which the devices available at any given time have relied upon other more mainstream technologies from which capsule builders have been able to borrow. As an inevitable consequence, device complexity and functionality have increased.
