  • Inkjet-Printing Technology: From a Droplet to Flexible Electronics and 3D Artificial Tissues

    Inkjet printing technology encompasses the generation, control and deposition of 10-100 um liquid drops. Besides graphic printing applications, new opportunities for inkjet printing are starting to be exploited commercially in the manufacture of high-value, high-precision products. The applications include flexible electronics such as sensors and logic circuits as well as 3D biological tissues and organs for regenerative medicine. This tutorial covers from the fundamentals of inkjet to the wide range of electronic and biological applications. The first part of the talk will provide the inkjet printing process from ink rheology to jet formation, drop impact and drying. Next, a wide range of inkjet printing applications in electronics and biotechnology will be presented. The electronic applications of inkjet include flexible thin-film transistors and circuits, active-matrix arrays, wearable sensors, solar cells and displays. Finally, another new application of inkjet - 3D printing of living cells and biomaterials for tissue engineering and regenerative medicine will be discussed. 

  • Distributed Printed Electronics for Sustainable Environmental Practices

    High spatial density monitoring of the environment is essential for improving the understanding and management of natural systems. This is of particular importance in managed soils, where sensing can enable optimization of agricultural inputs, improved crop yields, increased carbon/nitrogen storage, and enhanced soil health. Print-based manufacturing of electronic systems enables the fabrication of large numbers of unconventional devices that utilize a wide range of materials that are compatible with natural environments, allowing the capture of useful, high-density information in these environments. This short course will describe recent progress and future opportunities for enabling sustainable environmental practices through distributed monitoring using printed electronic devices, with a focus on application in plants and soils.

  • Flexible and Hybrid Electronics – A Tutorial

    Flexible and hybrid electronics (FHE) combine additively printed electronics on bendable, flexible, or stretchable substrates with the performance of silicon-based semiconductors to enable applications that include wearable medical devices and industry sensors. This short course will review the design and fabrication challenges associated with interfacing hard and soft electronic components, materials selection, printing, processing, and testing of FHE systems. Applications to medical and industrial sensors will be incorporated throughout this presentation and their “concepts of operation” will guide the evaluation of performance and reliability. Outcomes from this work are expected to inform the eventual scale-up to large- area, roll-to-roll manufacturing or integration on complex, non-planar surfaces, and solids.
