세미나 제목 : Molecule-Based Flexible and Stretchable Sensors

발표초록 :

With the advent of the Internet of Things (IoT), sensors are becoming increasingly important. Particularly, sensors based on molecules covering small organic molecules and polymers have recently attracted great interest due to their high potential for use in flexible, low-cost, solution-processable, large-area electronics. Functional properties of organic active layers can be tailored by rational molecular design or surface functionalization to enhance their selectivity and sensitivity. Compared with conventional sensing devices composed of two terminals, field-effect transistor (FET)-type sensors enable easy amplification of the detected signals and facile electrical tuning of the sensitivity by controlling the applied voltage on the third electrode, i.e., the gate terminal. Furthermore, nanoscopically engineered organic semiconducting materials have emerged as promising building blocks for high-performance flexible sensors. This talk will introduce recent technologies on molecule-based flexible and stretchable sensors, as the first part. In the second part, this talk will cover our recent works on molecule-based soft electronics. Unconventional organic semiconducting nanomaterials including single-crystalline nanowires, nanoporous organic semiconducting films, and core-shell structured 1-D nanomaterials have been fabricated and applied to high-performance flexible and wearable sensors such as photodetectors, chemical and biological sensors. In addition, the fundamental charge transport and photophysical phenomena of molecule-based active layers have been investigated.
