Silicon Microgravity commercialises MEMS-based sensing technologies spun out of Cambridge University, developing high-performance accelerometers, gyroscopes and MEMS gravimeters. The company targets two primary markets: inertial navigation—offering smaller, higher-accuracy MEMS accelerometers and gyroscopes—and gravity sensing, providing compact gravimeters for surveys and alternative navigation. Its technology is positioned for applications across defence, space, aerospace, robotics and geophysics, and the company says its MEMS accelerometers are already supporting advanced space programmes and satellite-enabled mineral exploration. SMG emphasizes production for extreme operating environments and is focused on scaling UK manufacturing and semiconductor production capacity. Early support included BP during development for oil and gas applications, and the company reports growing commercial validation from global customers and partners.
