The fully-recyclable, modular patch features easily removable electronic components, capable for later reuse. VTT made the patch from its new material cellulose e-skin, which replaces traditional plastic in wearable skin applications. It printed the nanocellulose material with carbon conductors and sensing electrodes.
“The healthcare industry has one of the heaviest environmental footprints, and manufacturers are increasingly faced with regulations to make more sustainable products. Bio-based substrates like cellulose e-skin are promising alternatives to fossil-based ones,” said Mohammad H. Behfar, senior scientist at VTT. “The tricky part is the fact that t…
