First Swallowable Electronic Devices
The FDA has approved a pill that can do it on its own by monitoring your insides and relaying the information back to a healthcare provider.
The pills, made by Proteus Digital Health, have sand-particle-sized silicon chips with small amounts of magnesium and copper on them. After they’re swallowed, they generate voltage as they make contact with digestive juices. That signals a patch on the person’s skin, which then relays a message to a mobile phone given to a healthcare provider. It’s only been approved for use with placebos right now, but the company is hoping to get it approved for use with other drugs (which would be where it would get the most use). (Via Popsci.com )
