Dear all, The next Future BNC Meeting will be this Thursday, 4/11 @ 12pm (lunch provided) in BRK 2001. Rahim Rahimi<https://engineering.purdue.edu/MSE/people/ptProfile?resource_id=116316>, Assistant Professor of Materials Engineering will present an overview of Nanomanufacturing for the first half then the remainder will be open for high-level discussion of collaboration opportunities that can lead to future center of excellence and/or also brainstorm about a shared vision for Birck. Laser processing and printing of multilayer films for inexpensive and flexible microsystems Flexible/stretchable electronics offer ideal properties for fabricating emerging health monitoring devices that can monitor the user’s well-being and their surrounding in a proactive and autonomous fashion. While the attractiveness of these devices are evident, they are often fabricated by conventional cleanroom required techniques that are either expensive or incompatible with rapid large-scale (e.g., roll-to-roll) production, which often prevents their translation into industry for addressing the community needs. In this talk, I will present a few inexpensive fabrication technologies that can be utilized for developing various flexible/stretchable physical and chemical sensors for wearable and lab-on-chip applications using novel inexpensive techniques including laser processing and printing. This presentation is divided into two main sections, each showcasing one of these technologies. In the first section, I will describe the use of localized CO2 laser irradiation to selectively convert thermoset polymer films (e.g., polyimide) into electrically conductive and highly porous carbon micro/nano structures. This process provides a unique and facile approach for direct writing of carbon-based conductive patterns on flexible polymer sheets in ambient conditions, eliminating complexities of current methods such as expensive CVD processes and complicated formulation/preparation of conductive carbon based inks used in inkjet printing. In this section, I will also demonstrate the use of laser ablation for selective patterning of conductive coatings from multilayer films such as ITO-coated PET and metalized paper as a simple and scalable alternative to conventional photolithography-based processes. In the second part of this talk, I will demonstrate a few strategies that were used to leverage printing technologies to create innovative platforms, including Smart dressing for monitoring and treatment of chronic wounds, disposable lab-on-chip diagnostic platforms, and electrochemical sensors for in-situ monitoring of soil nutrients. I will conclude by briefly commenting on our efforts to translate some of these technologies into clinical practice, as well as the future directions of this research and its potential combination with woven and non-woven smart textile-based systems. Below is the schedule of future BNC strategic thinking discussion meetings, please mark your calendars to attend if possible.
