               1. A head unit device for controlling motion of an object, comprising: 
            a chamber filled at least in part with a shear thickening fluid (STF), wherein the STF includes a multitude of piezoelectric nanoparticles; 
                a piston housed at least partially radially within the chamber, the piston configured to exert pressure against the shear thickening fluid in response to movement of the piston from a force applied to the piston from the object, wherein the movement of the piston includes one of traveling through the chamber in an inward direction and traveling through the chamber in an outward direction, wherein the STF is configured to have a decreasing viscosity in response to a first range of shear rates and an increasing viscosity in response to a second range of shear rates; 
                a set of radio frequency wireless field transmitter emitters positioned proximal to the chamber, the set of radio frequency wireless field transmitter emitters configured to provide a wireless field activation to the multitude of piezoelectric nanoparticles such that the STF is reconfigured to have the decreasing viscosity in response to a modified first range of shear rates and the increasing viscosity in response to a modified second range of shear rates; and 
                a set of radio frequency wireless field sensors positioned proximal to the chamber, the radio frequency wireless field sensors configured to provide a fluid flow response from the multitude of piezoelectric nanoparticles, wherein the fluid flow response is independent of the wireless field provided by the set of radio frequency wireless field transmitter emitters.
