Silicon Microgravity is a technology platform-based company focused on developing and applying innovative technology where we can apply gravity to create value.. We have developed a unique high performance, ultra-sensitive, yet robust MEMS resonant accelerometer. This has a projected resolution (while being incredibly small) of approximately one billionth of the Earth’s gravity.
