Review on the Electronic Pill system

Abstract

Annually, millions of people in the world suffer GI disease serious enough to require hospitalization. In over
one-third of these cases, the cause is never found. Despite standard invasive examination techniques, much of the GI
tract’s inner workings remain a mystery. Swallowable capsules have been evolving for almost half a century and are now
helping uncover GI tract mysteries in diagnostic and therapeutic applications. The electronic pill is one of the most
efficient drug delivery system. It uses four sensors , controller , antenna , power source and additional circuitry . This
paper deals with the detailed working of batteryless electronic pill , Technical challenges occurring in fabrication of an
electronic pill and research data from commercial capsules.
