Tattoo tech wearables

So-called tech tattoos could soon monitor your health, control objects or even give you a drunk test. These are not permanent ink tattoos (at least not yet), but instead a circuit imbedded in a clear plastic that you stick on your body.

A Chinese company demonstrated a product at this year’s tech show CES that monitors vital signs. The Wall Street Journal highlights other options, such as a tiny computer that can monitor the alcohol level. Or another that can fly a drone by monitoring arm movements.
