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.

Systems and devices to control linear, rotational, and/or arcuate motion are provided herein. In some examples, a pin system is configured for insertion in a door and/or door jamb, and to control motion of the door, such as a speed with which the door closes. In some examples, a hinge pin is configured to replace a conventional hinge pin and to control motion of the door. In some examples, a hinge system is configured to replace a conventional door hinge and to control motion of the door.
