Silicon Microgravity

Semi-conductor technology for the global motion and gravity markets

Silicon Microgravity (SMG) is a semi-conductor technology company developing MEMS (Micro Electro Mechanical Systems) devices with a focus on the global motion and gravity markets. The nano technology includes ultrahigh performance accelerometers and gyroscopes in low power, compact form factors that can be volume manufactured and disrupt today’s market for motion and gravity sensing technology.

Founded in 2015 as spin-out of Cambridge University, SMG’s technology is based on over 10 years of research and development that takes MEMS technology to new levels of performance and opens up a wide range of commercial opportunities.

Proposition (or Vision)

For the motion markets, this MEMS accelerometer and gyroscope technology will be integrated into a wide range of inertial navigation systems across wide ranging in markets such as defence, aerospace, autonomous vehicles and robotics.

On the gravity side, MEMS gravimeters will open up new markets for gravity sensing on earth and in space detecting density changes by monitoring changes in the earth’s gravity field for markets such as mineral exploration, tunnel / void detection and monitoring of carbon capture sites.

Investment Overview

“SAIC first invested in 2023 and followed on in 2025. The company is well run and regularly updates its shareholder base. We remain extremely upbeat about this disruptive technology and the recent commercial momentum especially the level interest and excitement from the early stage pilots.”   - Chris Hall, Investment Director

Founder Response

“It is a really exciting time for SMG as we commercialise our products in both Motion and Gravity divisions. The market traction is impressive. On the Motion side we have customers such as Northrop Grumman and SpaceX who have tested our devices and are now discussing long term contracts. On our Gravity side, the Critical Minerals market is ripe for our technology to help customers discover the mineral deposits the world needs with initial sales complete.”  - Francis Neill, Chief Executive Officer
