LEGO Mindstorms, PlayStation 2 and Furby all resonate today in their own way

Column  Twenty-five years ago this month I published a book called The Playful World that explored a simple idea: that the seeds of the future can be found in the present by considering the dazzling toys we started giving our children at the turn of the millennium.…

Color-Changing Organogel Stretches 46 Times Its Size and Self-Heals

1 month 3 weeks ago
alternative_right shares a report from Phys.org: Scientists from Taiwan have developed a new material that can stretch up to 4,600% of its original length before breaking. Even if it does break, gently pressing the pieces together at room temperature allows it to heal, fully restoring its shape and stretchability within 10 minutes. The sticky and stretchy polyurethane (PU) organogels were designed by combining covalently linked cellulose nanocrystals (CNCs) and modified mechanically interlocked molecules (MIMs) that act as artificial molecular muscles. The muscles make the gel sensitive to external forces such as stretching or heat, where its color changes from orange to blue based on whether the material is at rest or stimulated. Thanks to these unique properties, the gels hold great promise for next-generation technologies -- from flexible electronic skins and soft robots to anti-counterfeiting solutions. The findings have been published in the journal Advanced Functional Materials.
