Abstract
In many proposed applications of organic electronics it is important that the devices are flexible or even stretchable. This includes applications in rollable displays and solar cells, bio-integrated sensors, wearables, and more generally the internet of things (IoT). For these applications to be successful, the fabricated devices must function while being under significant mechanical loads. While organic semiconductors are generally considered “soft” and “flexible”, their mechanical behavior can actually vary widely, and understanding the mechanics of these materials in greater detail is necessary to ensure robust operation. In addition, understanding the thermomechanical properties of organic semiconductors provides another level of insight beyond devices withstanding stress and strain. By capturing detailed viscoelastic properties of these materials insights into processing, solid state morphology, and morphological stability can also be made. Thus mechanics of organic electronics has broad implications from fundamental science to device engineering. In this talk, I will discuss various activities in our research group related to this spectrum of mechanics research. Topics covered will include studying the thermomechanical properties of polymer semiconductors, development of stretchable polymer semiconductors and devices, and mechanical stability of films and devices for flexible and stretchable applications.
