Gallery: Feeling sick? Take a pill with a chip
Here's the pill in question, known as the iPill – a 11 x 26 mm capsule designed to deliver its load only when it reaches the right area of the intestines.
How does it know how far along the digestive tract it is? By analyzing the body's pH level as it travels. According to Philips, the body's "pH rises sharply upon exiting the stomach and becomes progressively alkaline from the upper intestine onwards".
The iPill can take the acidity information and combine it with data on how long it has spent in the body to decide the appropriate time to deliver the drug load it's carrying.
Jo Best of silicon.com points out that the iPill's cleverness doesn't stop there, however.

The program can then instruct the iPill how to drop its drugs – in a burst or released slowly, for example – as well as the location in the gut.
Other data, including body temperature, can be analysed by the iPill and transmitted back to a control unit outside the body via the pill's wireless transceiver. The unit can then amend the pill's instruction's accordingly.

According to Philips, however, the pill is ready for large scale manufacturing.
