High Power MEMS Switch for Use in Exploding Foil Initiator Applications

Tanner Research will develop, implement, and test a MEMS fabricated hybrid solid-state electronic switch for Phase I proof-of-concept demonstration of reliably initiating an EFI detonator for embedding into an electronic S&A device (ESAD). Tanner Research’s Phase I proof of concept hardware development is focused on developing and implementing the proof of concept high voltage switch, and secondly on integrating the switch into a COTS-type TRL-7 ESAD for empirical demonstration. Accordingly, the solid state discharge switch, with no moving parts, will provide accurate single- or multipoint timing, and repeatable operation for warhead and rocket motor fuzing applications. Objectively, the silicon-based discharge switch is being developed for reliable, low-cost insertion in electronic fuzing architectures, as well as providing robustness in high-G and high-radiation environments, along with repeatable operation for multi-option fuzing applications. Fundamental to this approach is the need for cost effective alternatives to existing solid-state trigger switches that have increased electronic fuzing costs to the point of infeasibility.
