Silicon Microgravity

Silicon Microgravity Limited (SMG) is a Cambridge-based startup specializing in MEMS (microelectromechanical systems) semiconductor technologies. They focus on developing and commercializing advanced MEMS gravity and inertial sensors. Their proprietary technology enables the production of high-performance MEMS devices designed for extreme operating environments, crucial for modern defense systems, satellite communications, navigation, sensing, and autonomous operations. SMG targets two primary markets: inertial navigation, offering more accurate, smaller, and lower-cost MEMS accelerometers and gyroscopes, and gravity sensing, providing robust, compact MEMS gravimeters for gravity surveys and alternative navigation. Their MEMS accelerometers are already being used in advanced space programs, including launch vehicles, lunar and planetary exploration, and satellite-enabled critical mineral exploration, as well as wider dual-use commercial and sovereign capability deployments. The company was founded as a spin-out from Cambridge University, with initial support from BP for oil and gas applications.
