Edible Technology Relays Medical Data from Inside the Body

Proteus Biomedicals, a company in California, has developed an intelligent pill that sends digital signals to an external receiver after being swallowed. The pill still works as an ordinary drug that a patient might take to control a health issue such as heart trouble or a psychiatric disorder. But it also has digestible sensors that are made of food products and are activated by stomach fluids. Once swallowed, the sensors can send a digital signal through the body to a receiver. The receiver date- and time-stamps, decodes, and records information about the drug and the dosage. It also measures and reports heart rate, activity, and respiratory rate
