The interactions between computers and the human body are becoming more of a reality than fiction both in medical applications and consumer products. To interface with biological tissues, highly adaptive and conformable electronics are needed. Organic electronics are emerging as key candidates for intimate body-machine interfacing. Our research aims to help move this field forward through the design and processing of novel organic semiconductors. We focus on these four core areas:

 

Materials design. The goal of our research is to leverage molecular design in advanced organic electronics  for current and future applications. We strive to tackle the long-standing challenge of relating structure to performance through design and processing of novel organic semiconductors. We are mainly interested in designer semiconducting polymers, corresponding composites, and 2D semiconductors.

Processing and characterization. The group aims to develop processing techniques for novel organic  materials to meet existing needs for large area device manufacturing. We are interested in developing  surface modification strategies, ink formulation, and film deposition routes suitable for industry-scale manufacturing. We are also interested in how molecular architecture relates to solid state structure and thin film behavior at the micro/meso/nano scale. Such relationship is of interest once translated into high performance organic electronics.

Bio-inspired electronics. We are interested in probing the materials' electronic performance in thin film based transistor devices. More specifically, we are interested in utilizing organic transistor devices with synaptic functionality (OFETs, OECTs) in bio-inspired electronic devices.

Organic neuromorphics. Of special interest to our group is the use of organic synaptic transistors for neuromophic devices. Such devices are aimed for energy-efficient sensing and computing applications to demonstrate electronics that learn! We want to combine our expertise in organic semiconductors with transistor device engineering to demonstrate next generation brain-like computing. We believe that intimate interactions between humans and computers are the future of electronics, and that highly-interactive, bio-compatible, and lightweight electronics, i.e. organic smart electronics, are key to realizing such integration!
