Originally shared by Wayne Radinsky"Motorola has shown off an electronic authentication tattoo and an FDA-approved pill that uses the body to transmit passwords, and says it wants to see a new generation of smartphones geared towards such wearable -- or edible -- technology."
"She showed off a stick-on electronic tattoo on her arm consisting of a wireless power coil, temperature, ECG, phone sensors, and a small LED with a wireless antenna border. Motorola is working with the inventors, Cambridge, Massachusetts firm MC10, on a version for authentication, she said, and they would be available in a wide variety of designs."
"Dugan also showed off a pill containing a switch and what she described as an "inside-out potato battery" that uses stomach acids as an electrolyte and causes the switch to flick on and off. The resulting "18-bit ECG-like signal" is then broadcast throughout your body for as long as the device remains in it."
