But unlike phones and smartwatches, which use tiny accelerometers or optical tricks to track the body, this system relies on how it is itself stretched and compressed.
The good news is that’s an engineering and design limitation, not a theoretical one — so a couple years of work and progress on the Electronics front and they could have a much more attractive system.
“We think one day it will be possible to create a full-body skin-sensor array to collect physiological data without interfering with a person’s normal behavior,” Stanford professor Zhenan Bao said in a news release.
While the sensor has been in the works for a while, it’s only recently that the team has started moving toward user testing at scale to see what exactly sweat measurements have to offer.
For flat, relatively simple electronics, roll-to-roll is a great technique, essentially printing the Sensors right onto a flexible plastic substrate that can then simply be cut to size.
These are far from the only flexible or skin-mounted electronics projects out there, but it’s clear that we’re approaching the point when they begin to leave the lab and head out to hospitals, gyms and homes.
