Thanks @MRSBulletin @Materials_MRS for highlighting our 3D #hydrogelsemiconductor and #hydrogelttransistor work.
#MaterialsNews: Researchers at @HKUniversity and @Cambridge_Uni elucidates the full potential of low-cost #3D #hydrogel 3semiconductors in the exclusive fabrication of 3D spatially integrated #transistors with a high on/off switching ratio.
5 years celebration of #WISE at Yangshuo, Guilin.

This is HUGE: A soft brain chip could fix Neuralink's biggest implant problem. Scientists have developed a new kind of ultra 3D soft semiconductor that could finally solve the biggest problem with brain implants: The body attacking them. Right now, most brain chips are made from rigid materials like silicon. Your brain hates that. It responds by building scar tissue around the implant, slowly killing signal quality and sometimes forcing the device to be removed. This new chip changes the rules. Instead of hard electronics, researchers created a soft, hydrogel based semiconductor that bends, stretches, and moves like real brain tissue. Because it physically matches the brain, the immune system is far less likely to treat it as an invader. The result? > Cleaner signals. > Longer lasting implants. > And a much lower risk of rejection. This is huge for brain computer interfaces (BCIs), the same class of technology Neuralink is working on. BCIs translate brain activity into commands, allowing people to control computers, prosthetics, or even regain movement and speech. The real breakthrough is compatibility. Instead of forcing the brain to tolerate electronics, this chip behaves like biology.
@ScienceMagazine Check this video associated with this cover, a “boopable transistor” 😀. Details can be found at @NerdyChristie
Anyone else hear "boop" every time this finger presses on this transistor? Or is it just me? Maybe it's just me... Anyhow, the story of this video and more of the best from @ScienceMagazine and science in this edition of #ScienceAdviser: science.org/content/articl…
@khademh Thank you Ali for bringing me to the field of hydrogels!
@sharpekat48 @ScienceMagazine Thanks for the suggestion! I think it is a step by step process, and finally go to medicine to help patients.. :)
Thanks @HKUniversity for the post! Hope our #3Dsemiconductor technology can find potential applications in energy efficient computing, neuroscience research and medicine!

New on Science Cover @ScienceMagazine today! We report a hydrogel semiconductor with record-high modulation thickness up to millimeter scales while maintaining a high switching on/off ratio.
This image shows three-dimensional, millimeter-thick, and cell-embeddable semiconducting hydrogel fibers. These fibers can be used to construct interwoven living transistors that mimic real neuronal connections in the brain, redefining the boundary between technology and life.
@_iainmcculloch @FabianoSimone We were talking about you! The Iain speed! 😀😀
Our pleasure to host Prof. Simone Fabiano for an inspiring lecture on organic electrochemical neurons. A short stay but a long hiking! 😂
Truly a focused symposium visioning the future of BME in different views. During our plenary talk, we share our views on wearable bioelectronics: materials, devices, and AI-embedded hardware-software co-design.
Amazing talks by Prof. Wei Gao, Prof. Sahika Inal, and Prof. Shiming Zhang at the iCanX HK Summit! It was an honor to host the session. Looking ahead to the next event! #Bioelectronics, #iCanX
