Lovely video by Nature with unpublished scientific footage giving a behind-the-scenes view into our recent paper on soft photonic skins.

Fantastic #scientificwork introduced below in the form of a great video, explaining that scientists were able to more or less reproduce the #camouflage #mechanism of #octopuses, during which pigment filled cells allow the fast change of coloration fitting to their actual surroundings. According to the new scientific findings, researchers created thin #polymerfilms that they can program to produce different textures and colors when bringing these films in contact with a fluid. The researchers name this mechanism a #tunable #photonicskin that might be used for example in wearable #devices or #robotics.

Glad to see our work on soft photonic skins that change colour and texture highlighted by Nature in a news story!
This artificial skin, inspired by octopuses, can change its colour and surface texture on demand

Midway through grad school, I was at the Monterey Bay Aquarium dazzled, watching cuttlefish change the colours and textures on their skin. This morning, our paper, "Soft photonic skins with dynamic texture and colour control" (rdcu.be/eX1Sw) was published in Nature.
An interdisciplinary collaboration between nanophotonics, soft matter µfluidics, with Nicholas A. GĂŒsken, @dijk_gerwin, Johan Carlström, Jennifer E. Ortiz-CĂĄrdenas, Peter Suzuki, Bohan Li, @forydcelab, @asalleo and finally my PhD advisors, Nick Melosh and @BrongersmaMark
This nice News and Views piece by Benjamin Renz and Na Liu give a nice perspective of the work. nature.com/articles/d41586-0âŠ
Our photonic skins can be programmed to change texture (e.g. wavy vs flat, or matte vs glossy) and color patterns. We used electron beams to "write" different patterns into the films by changing how they swell in water. The video shows how a color pattern changes in real time.

#Heat treatment enhances #Pedot:PSS polymer stability in bioelectronics, eliminating chemical additives. This method improves conductivity and durability, offering a simpler fabrication process for implantable devices. @advmater doi.org/g88c9w techxplore.com/news/2025-03-âŠ

đšLarge video-language models LLaVA-Video can do single-video tasks.
But can they compare videos?
Imagine youâre learning a sports skill like kicking: can an AI tell how your kick differs from an expert video?

Do you like working with PEDOT:PSS but are tired of dealing with cross-linkers? In our recent work led by @sdoshi0 and Margaux Forner, we show that PEDOT:PSS becomes water stable after baking at 150 °C for 2 min. Now available at @AdvPortfolio: advanced.onlinelibrary.wileyâŠ

Electrochemically mutable soft metasurfaces based on soft conducting polymers exploit the deformability of soft materials through swelling to dynamically tune the shape and associated resonant response of the metasurface devices. @Stanford

Excited to share our work, on developing soft nanoscale optical modulators by using the swelling of soft polymer materials, now published in @NatureMaterials! Huge thanks to @BrongersmaMark @AppelGroup @scotttomkeene and collaborators.
