Abstract

Biological tissues are mechanically soft, with complex, time-dependent 3D curvilinear shapes; modern microfluidic technologies are rigid, with simple, static 2D layouts. Eliminating this profound mismatch in physical properties will create vast opportunities in man-made systems that can intimately integrate with the human body, for diagnostic, therapeutic or surgical function with important, unique capabilities in fitness/wellness, sports performance and clinical healthcare. Over the last decade, a convergence of new concepts in materials science, mechanical engineering, electrical engineering and advanced manufacturing has led to the emergence of diverse, novel classes of 'biocompatible' electronic and microfluidic systems with skin-like physical properties. This talk describes the key ideas and presents some of the most recent device examples, with a focus on microfluidic platforms that can capture, manipulate and perform biomarker analysis on microliter volumes of sweat, with applications in precise hydration management in sports and fitness, including commercial devices featured on celebrity sports figures with Gatorade.
