New 'intelligent pill' releases correct amount of medicine
An "intelligent pill" has been developed that, once swallowed, will release the correct amount of medicine according to what the body needs.
Dubbed the "iPill", it contains a microprocessor, battery, wireless
radio, pump and a drug reservoir to release medication in a specific area in
the body.
Designed by Philips, the Dutch electronics giant, the iPill capsule measures
acidity with a sensor to determine its location in the gut, before releasing
the drug.
