Miniaturization of Ground Shock Sensors

SRI's research in miniaturization of ground shock sensors is a critical component in small-scale testing and analysis to determine the effects of ground shocks and airblasts. Because certain measurement parameters are altered when the scale of an experiment is reduced, it can be difficult to obtain precise measurements. SRI has developed instruments for conducting the experiments, including high-range accelerometers, and a miniature version of the Mutual Inductance Particle Velocimeter (MIPV) transducer. SRI's sensors are tested using the laboratory Hopkinson bar technique. The need for these miniaturization testing techniques is likely will grow as resources for large-scale experiments become more limited.
