Low-cost prosthetic foot mimics natural walking

Engineers have developed a simple, low-cost, passive prosthetic foot that they can tailor to an individual. Given a user’s body weight and size, the researchers can tune the shape and stiffness of the prosthetic foot, such that the user’s walk is similar to an able-bodied gait. They estimate that the foot, if manufactured on a wide scale, could cost an order of magnitude less than existing products.

Personalized 'deep learning' equips robots for autism therapy

Researchers have now developed a type of personalized machine learning that helps robots estimate the engagement and interest of each child during these interactions, using data that are unique to that child. Armed with this personalized ‘deep learning’ network, the robots’ perception of the children’s responses agreed with assessments by human experts, with a correlation score of 60 percent.

Recreating the chameleon: Material mimics color changes of living organisms

Researchers created a material containing photochromic dyes, crystals providing structural coloration, and a colored background that mimics the color changes that animals such as frogs, chameleons, and octopuses can display. This material could display different patterns and images depending on whether it was exposed to visible or ultraviolet light, or had a white or black background, which suggests its potential application in a range of next-generation display technologies.
