An American biomedical company has signed up with a British healthcare firm to sell digestible sensors, each smaller than a grain of sand, that can trigger the transmission of medical information from a patient's body to the mobile phone of a relative or carer.
The aim is to develop a suite of "intelligent medicines" that can help patients and their carers keep track of which pills are taken at what time of day, in order to ensure that complex regimes of drugs are given the best possible chance of working effectively.
