Conductive and Stretchable Adhesive Electronics with Miniaturized Octopus‐Like Suckers against Dry/Wet Skin for Biosignal Monitoring

Abstract: High adhesion and water resistance on skin surfaces are highly demanded properties for wearable and skin‐attachable electronics in various medical applications. Here, stretchable electronics with octopus‐like patterns (OPs) imprinted on a carbon‐based conductive polymer composite (CPC) film are presented. The bioinspired conductive suckers with dome‐like architectures are successfully exploited to sustain weight (500 g) in underwater, wherein this performance is known to be challenging. In addition, the artifi… Show more

“…By focusing on adhesion mechanisms used in the animal kingdom, including well-known examples such as the gecko or octopus, wearable devices recorded vital signals even from wet skin while bypassing any toxicity induced by the currently used adhesives that are based on acrylic compounds. [202][203][204] One example includes stretchable electronics with octopus-like patterns imprinted on a carbonbased conductive polymer composite film (Figure 8c). [203] These bioinspired conductive suckers allow high adhesive capabilities under both dry and wet conditions on silicon (5.24 N cm −2 ) and skin replicas (1.89 N cm −2 ) without leaving behind residues after detachment, even with an effortless peel-off procedure.…”

“…In these wearable electronic or photonic sensors, their intimate coupling to the skin is of tremendous importance, as it determines the sensing quality, stability, and reliability while minimizing the motion artifact . However, a stable and robust adhesion to the skin is challenging, as the skin not only is a dynamic surface with low surface energy (25–29 mJ m −2 ) but also possess multiscale surface textures.…”
