Researchers at the University of Illinois at Urbana-Champaign are developing tiny sensors that can monitor temperature and pressure within the skull and then dissolve harmlessly into the cranial fluid.

What if wearables like Fitbits and the Apple Watch represent the infancy of on-body health sensors, something we'll one day look back on the way we now look at the clunky, boxy mobile phones of the 1980s? A number of researchers are working on ultrathin, flexible sensors that could be applied to the skin like smart tattoos, or even applied to the surface of organs inside the body to continually monitor vital signs or to deliver time-released drugs.

A number of digital health apps in the Google Play store send unencrypted information over the internet and use of third party services, according to a graduate thesis from University of Illinois at Urbana-Champaign student Dongjing He.
