What SKIN ?
Article fails to say what area of your skin gets this neat little sensor.
My first thoughts were an elbow or knee or finger but those areas would probably have no need of measuring anything .... then I of course thought of my nether parts.
At 70, my wife would probably like an alarm to ring if there was anything worth paying attention to.
Article is vague but thx for the post.

It seems more like either sensors for medical measurements, like body temperature, blood oxygen content or pulse, or to detect and send out nerve impulses for prosthetic limbs. It doesn’t help that the pick-up shown looks more like the make-up for Seven of Nine than anything normal people would actually wear.
