Getting Stuck and Breaking Free: Adhesion, Friction,
Strength, and Toughness
(IMECE2019-14006)

Abstract: The anterior cruciate ligament, or ACL, of the knee
is a soft tissue structure comprised of two main bundles of
hierarchical collagenous structures. As with all soft tissue, the
ACL is extremely difficult to mechanically test, and determining
its nonlinear, anisotropic mechanical response has remained
elusive. Yet, obtaining the mechanical properties of the
ACL is exceedingly clinically relevant to the design of better
replacement grafts for torn ACLs or to prevent ACL tears
in the first place. This talk will focus on our recent efforts to
characterize the ACL response utilizing full-field displacement
measurement techniques that offer more accurate, repeatable,
and comprehensive experimental data than traditional testing
methods. We have pioneered full-volume characterization
techniques that provide much needed insight into the
inaccuracies associated with many current experimental
protocols and also the shortcomings of some popular
constitutive models in capturing the full 3D response of the
ACL. I will describe how we use these data to develop an ACL
constitutive model for implementation into computational
models of the knee during regular gait and under impact
loading simulations. Accurate computational models of the
knee such as ours may one day be used to guide clinical
practice to intervene to prevent an ACL injury or to determine
the best course of action to repair an injury.

Taking Microfluidics From Research Ideas to a Real
Product
(IMECE2019-14008)
Bruce K. Gale
University of Utah
Abstract: Microfluidics have promised to revolutionize medicine xlv
and biology for decades now, but the promise has been slow
to be realized. Many applications of microfluidics are now
having an impact. This presentation will focus on a few
technologies and how they have transitioned (or begun to
transition) from the research lab to commercialization. The talk
