New ‘silver bullet’ pill powered by your own stomach acid sends data straight to your phone while it works

Researcher Dr Phillip Nadeau, from Massachusetts Institute of Technology, said: ‘The self-powered pill would monitor your vital signs from inside for weeks.

Small sensors continually monitor temperature and heart rate.

The 30mm-long device took six days to travel through the digestive tract of a pig.
