Silicon Microgravity secures a £6m follow-on round led by West Hill Capital to develop high-performance sensors for navigation and sensing

Silicon Microgravity is developing microelectromechanical systems (MEMS) technologies for high-performance sensing and navigation. Its technology is used to produce accelerometers, gyroscopes and gravity sensors for demanding environments in sectors such as defence and aerospace.

Silicon Microgravity, a startup developing microelectromechanical systems (MEMS) technologies for high-performance sensing and navigation, has raised £6 million in a funding round led by West Hill Capital. The UK Innovation & Science Seed Fund (UKI2S) also invested. Oxford Innovation Finance made a follow-on investment through the Oxford Innovation EIS Growth Fund.

Based in Cambridge, Silicon Microgravity, known as SMG, uses its proprietary technology to produce specialised accelerometers, gyroscopes and gravity sensors designed to operate in demanding environments. The sensors have applications across defence, aerospace, space exploration and other sectors that require precise and reliable sensing.

SMG's inertial sensors have potential applications in navigation systems where access to GPS may be limited or unavailable, including autonomous operations and space programmes. Its gravity-sensing technology also has potential for subsurface imaging, which can identify variations in underground density for uses such as critical mineral exploration and infrastructure development. SMG is working to scale its manufacturing capability and build on commercial interest from international customers and partners.

It is the second time Oxford Innovation Finance has invested in SMG through its EIS Fund. The funding will support SMG's plans to expand its UK manufacturing and engineering capabilities and accelerate commercial partnerships across Europe and the United States.

We’re pleased to have Oxford Innovation Finance continuing to support Silicon Microgravity through this latest investment. Their backing through its EIS Fund in both 2023 and now reflects the progress we’ve made and the opportunity ahead for our technology. The funding will help us expand our engineering and manufacturing capacity in the UK and accelerate commercial deployment across defence, space and other markets where high-performance sensing and navigation are increasingly important.

Francis Neill, CEO

Silicon Microgravity is developing highly differentiated MEMS technology with the potential to address important challenges in navigation, sensing and subsurface imaging. Since our initial investment in 2023, the company has continued to develop its technology and progress its commercial opportunities. We’re pleased to be investing again as part of this latest funding round, supporting the team as it scales its UK manufacturing capability and brings its technology to a wider range of markets.
