High-Temp EFPI Accelerometer Technology
Active
Description
EFPI based sensor for accelerometer that can withstand temperatures up to ~1800°F Replacing tiny fiber reflector end with reflective metallic diving board deflector Can reach temperatures up to 1800 °F degrees, limits of gold coating on EFPI fiber, different coated fibers currently under research for survivability far beyond 1800°F Immune to EMI and thermal effects (plasma) experienced during hypersonic flight Can be plugged into and interrogated via pre-existing WDM flight rated and proven systems
Benefits
Measure dynamic accelerations at extreme temperatures (~1800 F) during ground and/or high speed flight (hypersonic)

How to get involved
This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
