A New Membrane Can Substantially Upgrade Wearable Energy Generators (3 minute read)

Scientists from Japan and China have created a new triboelectric fabric that can generate power from body motion while maintaining the flexibility and breathability of modern clothing. The team achieved these properties by using a multilayered triboelectric nanogenerator, nanowires, and a polystyrene charge storage layer. The technology is currently not able to generate large amounts of power, but the development of the new material represents a substantial advancement towards the future of wearable applications.

Sponge Genes Hint at the Origins of Neurons and Other Cells (7 minute read)
