Chip Can Project Video the Size of a Grain of Sand
Summary
IEEE Spectrum covers a MEMS array photonic chip capable of projecting video at micron scales, using an array of cantilevers driven by aluminum nitride piezoelectric layers. The article highlights the MITRE Quantum Moonshot collaboration, demonstrates a tiny Mona Lisa projection, and discusses potential applications in quantum computing, AR imaging, 3D printing, and lab-on-a-chip devices, while outlining fabrication challenges and future directions.
