New Medical Devices: Sensor Tattoos

Smart Planet recently posted on how an iPhone monitors blood below the skin in via a digital tattoo where the ‘ink’ contains tiny sensors that can read – with the help of the phone’s camera – blood levels of sodium, glucose, and even alcohol.

The patch would be applied to the body like a temporary tattoo and would contain the electronic components necessary for sensing, communications and relaying information from the body to a monitoring device.
