Paintable Skin Electrode That Tracks Your Body Researchers from the Pennsylvania State University have developed a paintable on-skin dry electrode that sticks comfortably to the skin and reads biological signals with impressive stability. Because the sensor starts as a liquid paint, it flows into the microscopic lines, wrinkles, and pores of your skin before it dries. This creates a perfect, seamless bond that… |

Every Pixel Has Its Own Microcontroller Imagine a display where every single pixel has its own brain. That's the ambitious idea creator bitluni set out to bring to life in a six-month engineering project. Instead of relying on a central GPU, the display turns every pixel into an independent computing node. The ultimate goal is a 65,536-core QVGA display, while the first working prototype already features 8,192 RISC-V… |
