Chip Can Project Video the Size of a Grain of Sand
Researchers from MIT, the University of Colorado, Sandia National Laboratories and MITRE have unveiled a sub‑0.1 mm² photonic chip that can steer light with unprecedented speed. The device uses voltage‑actuated metallic cantilevers to project up to 68.6 million light spots per second per square millimeter—over fifty times faster than existing MEMS scanners. Demonstrations include a 125‑micrometer Mona Lisa image and a full video of “A Charlie Brown Christmas.” The technology promises to simplify control of millions of qubits and to accelerate imaging‑heavy applications such as AR and biomedical diagnostics.
Your Watch Will One Day Track Blood Pressure
Researchers at the University of Texas at Austin demonstrated a non‑contact method for measuring blood pressure by reflecting near‑field radio waves off the wrist. They built a wearable prototype using a patch antenna, circulator and a custom 2.4 GHz integrated circuit...
