Recording multiple signals simultaneously is more difficult because sensors must maintain reliable contact with the body even through hair, sweat and everyday movement.
A team of researchers led by Penn State developed an ultrasoft, adhesive and printable hydrogel - a soft, water-rich material that mimics the flexibility of living tissue - designed to conform to dry, wet, moving and hairy skin. In proof-of-concept experiments, the...
