Biomimetics: Highly Permeable Skin Patch with Conductive Hierarchical Architectures Inspired by Amphibians and Octopi for Omnidirectionally Enhanced Wet Adhesion (Adv. Funct. Mater. 13/2019)

In article number 1807614, Changhyun Pang and co‐workers report highly air‐permeable, water‐drainable, and reusable skin patches with enhanced omnidirectional peel resistance and pulling adhesion, inspired by the toe pads of tree frogs and convex cups in the suckers of octopi. The patch can be utilized as flexible electrodes by coating reduced graphene oxides to monitor electrocardiography signals without delamination on skin in sweaty and even flowing water conditions.

A team of scientists from Sungkyunkwan University have designed adhesives based on the mechanism underlying the unique multiscale architecture of tree frog toepads for effective omnidirectional adhesion against rough surfaces in various wet conditions.

To further enhance the adhesion capability of the skin patch on wet surfaces, they then incorporated a suction effect yielded by convex cups, inspired by the protuberance structures within octopus suckers.

Several analyses later, what they had was a novel, reversible adhesive skin patch with high air permeability and water drainage. The adhesive patches were then spray coated with reduced graphene oxide nanoplatelets to be used as flexible electrodes for biosignal monitoring without delamination against dynamic wet skins.

The authors believe that this this amphibian- and octopus-like adhesive could replace the conventional adhesives used in skin patches and wearable/implantable devices.

“Our results shed light on the development of in vitro and in vivo integrated medical devices for inner and outer organ applications.” they conclude.
