Silicon Designs

For more than three decades, SDI has been at the forefront of designing and producing surface mount accelerometers built to withstand the rigors of military, inertial, defense, industrial, and research and development operations. Whether in the skies, underwater, or on the battlefield, our accelerometer modules deliver the reliability and precision demanded by the most critical military applications.

SDI’s journey commenced in the mid-1980s with the receipt of an SBIR award for a radiation-hardened accelerometer under the Star Wars program. Since then, our expertise has evolved, leading to the development of our industrial-grade MEMS DC accelerometers, the favored choice for many defense programs.

Acknowledged for innovation and honored with over two dozen SBIR awards, including induction into the Space Technology Hall of Fame, SDI collaborates extensively with the US Government, Military divisions, Primes, and subcontractors, providing custom and COTS accelerometers for diverse applications and research programs.
