Lovely video by Nature with unpublished scientific footage giving a behind-the-scenes view into our recent paper on soft photonic skins. @BrongersmaMark , @asalleo @fordycelab @dijk_gerwin Public link to original paper: rdcu.be/eX1Sw

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. © this text #StefanFWirth Berlin 2026 Reference: Doshi, S., Güsken, N.A., Dijk, G. et al. Soft photonic skins with dynamic texture and colour control. Nature 649, 345–352 (2026). doi.org/10.1038/s41586…

Glad to see our work on soft photonic skins that change colour and texture highlighted by Nature in a news story!

An interdisciplinary collaboration between nanophotonics, soft matter &microfluidics, with Nicholas A. Güsken, @dijk_gerwin, Johan Carlström, Jennifer E. Ortiz-Cárdenas, Peter Suzuki, Bohan Li, @forydcelab, @asalleo and finally my PhD advisors, Nick Melosh and @BrongersmaMark

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.

This nice News and Views piece by Benjamin Renz and Na Liu give a nice perspective of the work. nature.com/articles/d4158…

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-b…

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.wiley.com/doi/10.1002/ad…

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 nature.com/articles/s4156…

@AppelGroup @BrongersmaMark @StanfordMSE Thanks Eric! It’s fun thinking back to our early brainstorming way back during your grad polymers class!

Glad to be part of this super cool work from @sdoshi0 @BrongersmaMark and Nick Melosh! Go @StanfordMSE!!

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. Link to paper: lnkd.in/g-pUC-Qx
