Microchips in pills could soon allow doctors to find out whether a patient has taken their medication. The digestible sensors, just 1mm wide, would mean GPs and surgeons could monitor patients outside the hospital or surgery.

The ‘intelligent’ medicine works by activating a harmless electric charge when drugs are digested by the stomach.

This charge is picked up by a sensing patch on the patients’ stomach or back, which records the time and date that the pill is digested. It also measures heart rate, motion and breathing patterns.

The information is transmitted to a patient’s mobile phone and then to the internet using wireless technology, to give a complete picture of their health and the impact of their drugs.
