"Stretchy Electronic Material Gains Strength Upon Impact, Mimicking 'Oobleck'"

Researchers at the University of California, Merced, have developed a conductive polymer film that toughens up upon impact, similar to the behavior of "oobleck," a non-Newtonian fluid. The material, made by combining long spaghetti-like polymers with shorter molecules, deforms and stretches in response to impact without breaking apart. This "adaptive durability" could be applied to wearable electronics and flexible health monitoring devices, with potential for 3D printing compatibility.

Cracking the Code of Oobleck: Unraveling the Mystery of its Dual Nature

Scientists at the University of Chicago have used dense suspensions of piezoelectric nanoparticles to study the molecular behavior of oobleck, a non-Newtonian fluid that can behave as both a liquid and a solid. Oobleck's viscosity changes in response to applied strain or shearing force, making it a shear-thickening fluid. The researchers developed a mathematical model to predict the transition of oobleck from liquid to solid and back again, taking into account factors such as particle size and electrical charges. Computer simulations of previous experiments confirmed the accuracy of the model's predictions.
