Silicone Membrane for Wearable Devices is Comfortable and Breathable

A silicone membrane for wearable devices is more comfortable and breathable thanks to better-sized pores made with the help of citric acid crystals. The new preparation technique fabricates thin, silicone-based patches that rapidly wick water away from the skin. The technique could reduce the redness and itching caused by wearable biosensors that trap sweat beneath them. Read on to learn more.

3D-Printing Flexible Devices without Mechanical Joints

Eva Baur, a Ph.D. student, used 3D-printed double network granular elastomers (DNGEs) to print a prototype ‘finger,’ complete with rigid ‘bones’ surrounded by flexible ‘flesh.’ The finger was printed to deform in a pre-defined way, demonstrating the technology’s potential to manufacture devices that are sufficiently supple to bend and stretch, while remaining firm enough to manipulate objects.
