Résumé: At present a large portion of research in circuits and systems area are being conducted in IoT area. Due to advantages of flexible printed devices, many researchers are considering fabricating the IoT devices with printed and flexible electronics technology. The printed and flexible electronics industry is evolving at a healthy pace and is witnessing an active transition from research and development phase to commercialization phase. Advancements in printing technologies and material science have been instrumental in the growth of printed and flexible electronics. As the demand for more flexible, low cost, compact, and power efficient electronic products is increasing, printed and flexible electronics is gaining momentum as it incorporates all the above mentioned features. Although printed and flexible devices are economically attractive, their operational performance is generally poor. This is significant enough to limit the number of commercially available printed devices today. Most of the commercially available printed and flexible devices are NFC tags, glucose and force sensors. The webinar is intended to identify the root causes of some of the limitations associated with development of printed devices and propose methods to circumvent them. It will cover comparison of conventional technologies, materials used for flexible printed devices, their limiting factors and present emerging materials and technologies that can overcome those limitations. It will also cover how new circuit topologies can improve performance of flexible printed devices. The tutorial will present some examples of high performance flexible printed devices from the author's laboratory. At the end, the webinar will allow the attendees to brainstorm on possible ways to improve the performance of a specific printed flexible device.

Note biographique: Sharmistha Bhadra is an assistant professor in the department of Electrical and Computer Engineering at McGill University. Her current research interests are in the area of printed and flexible hybrid electronics, microelectronics, microelectromechanical systems, and sensors and wearables. She has published over 75 papers and holds 2 patents in these areas. Her research program at McGill University leverages conventional design and development tools as well as printed electronics technology to find cost effective and high performance innovative electronic technology. One of her more concrete short term research goals is to use printed and flexible hybrid electronics technology to develop high performance sensors, wearables and other electronic components. She has organized special sessions and presented tutorials on printed and flexible devices in many conferences such as IEEE Sensors 2020, IEEE International Symposium on Circuits and Systems 2020, IEEE FLEPS 2020, IEEE FLEPS 2021, IEEE sensors 2019. She has given invited talks on low cost sensors and devices in different venues such as IEEE International Flexible Electronics Conference 2019, Vancouver IEEE Electron Devices Chapter Technical Talk, Vancouver IEEE Sensor Chapter Technical Talk, IEEE Newfoundland Labrador Computer, Communication, and Circuits & Systems Joint Societies, RsSMiQ Day 2019.
