Abstract

A head unit device for controlling motion of an object includes shear thickening fluid (STF), an alternative STF (ASTF), and a chamber configured to contain a portion of the STF and the ASTF. The chamber further includes a piston compartment and an alternative reservoir. The head unit device further includes a reservoir injector configured within the chamber, and a piston housed at least partially radially within the piston compartment. The chamber further includes a set of fluid flow sensors and a set of fluid manipulation emitters to control the reservoir injector to adjust flow of the ASTF from the alternative reservoir to the piston compartment to cause selection of one of a variety of shear rates for a mixture of the STF and the STF within the piston compartment.
