Dutch group Philips has created what it's calling an "iPill" capable of measuring acidity with a sensor to determine its location in the body. The capsule contains a microprocessor, battery, wireless radio, pump and a drug reservoir to release medication in a specific area in the body. The benefit is in being able to treat digestive tract disorders such as Crohn's disease by releasing its payload directly to the location of the disease thereby lowering the required doses and reducing side effects.
