Presently, engineers lack sensors capable of directly measuring shear under the extreme flow conditions encountered in racing and propulsion systems. Silicon Audio is developing an innovative solution to address this long-standing need – in the form of a compact, robust, broadband shear sensor. Applications for the shear sensor technology include military applications, skin-friction sensors in university shock tunnel test facilities, commercial aviation, and autoracing industries.
The Silicon Audio shear sensor innovation project uses high-temperature ferroelectric materials to measure pressure and shear stress across two dimensions.
The Silicon Audio approach to developing a high-temperature, robust shear sensor leverages micromachining (i.e., MEMS) processing techniques.
The shear sensor development project takes advantage of the properties of piezoelectric materials to measure shear directly at the surface level.
