The challenge of micro- and nano-fabrication lies in the difficulties and costs associated with patterning at such high resolution. To make such promising technology – which could enable pervasive health monitoring and disease detection/surveillance - more accessible and pervasive, there is a critical need to develop a manufacturing approach such that prototypes as well as complete manufactured devices cost only pennies. To accomplish this, instead of relying on traditional fabrication techniques largely inherited from the semiconductor industry, we have developed a radically different approach. Leveraging the inherent heat-induced relaxation of pre-stressed thermoplastic sheets – commodity shrink-wrap film - we pattern in a variety of ways at the large scale and achieve desired structures by controlled shrinking down to 5% of the original, patterned sizes. The entire process takes only seconds yet enables us to ‘beat’ the limit inherent to traditional ‘top-down’ manufacturing approaches. With these tunable shape memory polymers, compatible with roll-to-roll as well as lithographic processing, we can robustly integrate various materials from thin metal films to various nanomaterials in order to achieve extremely high surface area, densified, and high aspect ratio nanostructures directly into our microsystems.
Michelle Khine is an Associate Professor of Biomedical Engineering, Chemical Engineering and Materials Science at UC Irvine. Michelle was recently appointed Director of Faculty Innovation at the Henry Samueli School of Engineering and as Director of BioENGINE (BioEngineering Innovation and Entrepreneurship) at the Institute for Innovation at UC Irvine. She was an Assistant & Founding Professor at UC Merced. Michelle received her BS and MS from UC Berkeley in Mechanical Engineering and her PhD in Bioengineering from UC Berkeley and UCSF. She was the Scientific Founder of Fluxion Biosciences, Shrink Nanotechnologies, Novoheart, and most recently, TinyKicks. Michelle was the recipient of the TR35 Award and named one of Forbes ’10 Revolutionaries’ in 2009 and by Fast Company Magazine as one of the '100 Most Creative People in Business' in 2011. She was awarded the NIH New Innovator's Award, was named a finalist in the World Technology Awards for Materials, and was named by Marie‐Claire magazine as 'Women on Top: Top Scientist' and was recently inducted as a Fellow of AIMBE (American Institute of Medical and Biological Engineering). She is currently working on a novel 'co-op' with her students, 'A Hundred Tiny Hands' to promote STEM outreach.
