Transparent flexible gas sensor based on ionic liquid towards environmental monitoring
Smart sensors for real-time detecting gas phase substances are essential for a lot of potential application such as wearable electronics, intelligent diagnosis, environmental monitoring, etc. at the coming era of internet of things (IoTs). Flexible, transparent sensing devices will enable easier and more comfortable integration with other consumer electronics in our daily life. Ionic liquid, as an emerging sensing material, exhibits potentials with thier high sensitivity, excellent transparency, and intrinsic flexibility. Yet their poor selectivity towards various components hinders the wide application of those devices, where, therefore, research focus is desired.
Keywords: Gas sensor, ionic liquid, nano fabrication
The topic is for 1 student; the work is mainly on experimental work, and is suitable for candidates who are interested in experimental research; the planed time duration is about 6 months.
The student will gain abundant experimental experience on nanofabrication and characterization by personaly operating the advanced fabrication and characterization equipment. Meanwhile, the student will learn the knowledge on the working mechanism and testing process of chemiresitive gas sensors.

The aim of this project is to investigate the selectivity enhancement of ionic liquid gas sensors induced by the surface functionalization with different noble metal nanoparticles.
To achieve this goal, the student will be involved in the following activities:
1. Preparing and printing ionic liquid-polymer composite structures with 0.1 – 1 μm features using Nanoscrible 3D high resolution printer (at cleanroom of APT Lab).
2. Decoration noble metal nanoparticles using electron-beam evaporator (at cleanroom of FIRST center)
3. Characterization on the morphology printed sensing structures with scanning electron microscope (at APT Lab)
4. Sensing performance characterization of the printed ionic liquid sensors, where the targeted analytes include various gas pollutants like VOCs, CO, NH3 etc. (at APT Lab)
5. Data analysis towards the response of fabricated sensing arrays.
