In my lab, we are exploring various rapid-prototyping methods to fabricate flexible sensors and actuators on low-cost disposable substrates. Among the more promising approaches is the use of CO2 laser for surface treatment and micromachining of cellulose-based and polymeric materials. Using this method, one can perform both surface-energy modifications and micromachining on the same substrate and in the same setup. In this talk, I will focus on laser-treated hydrophobic paper as a low cost substrate for flexible electronics. In particular, I will elaborate on some of our recent work towards the development of flexible smart dressings (incorporating chemical sensors, electrochemical power sources, and drug delivery modules) for chronic wound management.
Babak Ziaie received the Ph.D. degree in electrical engineering from the University of Michigan, Ann Arbor, MI, USA, in 1994. From 1995 to 1999, he was a Postdoctoral Fellow and an Assistant Research Scientist at the Center for Integrated Microsystems (CIMS), University of Michigan. He subsequently joined the Electrical and Computer Engineering Department, University of Minnesota as an Assistant Professor (1999–2004). Since January 2005, he has been with the School of Electrical and Computer Engineering, Purdue University, West Lafayette, IN, USA, where he is currently a Professor. His research interests include clinical applications of MEMS and microsystems, mobile health (mHealth), and biomimetic sensors and actuators.
