A method for execution by a computing entity includes interpreting a fluid flow response from a set of radio frequency wireless field sensors to produce a piston velocity and position of a piston associated with a head unit device that includes a chamber filled with a shear thickening fluid (STF) that includes a combination of a multitude of piezoelectric nanoparticles and a multitude of magnetic nanoparticles. The method further includes determining a shear force based on the piston velocity and the piston position. The method further includes determining a desired response for the STF based on the shear force, the piston velocity, and the piston position. The method further includes generating a wireless field activation based on the desired response for the STF and outputting the wireless field activation to a set of radio frequency wireless field emitters positioned proximal to the chamber.
