"We are going to see more sensors everywhere. It's only a matter of time before those migrate under our skin into our bodies," said Peter Eckersley, the lead technologist at the Electronic Frontier Foundation. Much like wearable devices, which can capture data about a person's activity levels, sensors inside the body can be used to collect information about what is going on inside a person's body.
 
"There's going to be a ubiquitous data collection. Right now, the data is coming from the phone and wearable devices, but eventually some will be within our bodies. And having that data available can mean enormous health benefits," Eckersley said.
