Chemical Sensing Platform to Accelerate Real-World Interfacing

• Chemical sensing technology has been the most valuable engineering field in current and future society due to its ability to detect invisible chemical molecules and predict and alarm future accidents. Performances of the chemical sensor have been greatly improved but there is still long-standing gap between commercial devices and field-required performances of chemical engineering. We are interested in a breakthrough in bottlenecks of conventional chemical sensor technology by leveraging state-of-the-art nanotechnology and channel fabrication technology, and eventually, hope to accelerate the real-world interfacing of chemical sensors.

• We have designed and controlled the whole stage of the solid-state sensor development/fabrication loop: From channel material selection - surface chemistry & nanostructure design - device integration & measurement - to signal analysis using machine learning and mathematical model. With this nanotechnology-leveraged sensor design feedback loop, we have developed high-performance chemical sensors with superior response time, sensitivity, selectivity, and applied those to various targets including human, industry, environment, and vehicle monitoring.
