Portable/Wearable Sensors for Human Body Monitoring

Abstract:
Non-invasive human body monitoring is essential to protect warfighters in operation. Volatile organic compounds (VOCs) in exhaled breath provide abundant physiological information, and detection of VOCs with miniaturized devices is crucial for wearable and flexible sensor suites. Currently, we are developing peptide-functionalized carbon nanotube (CNT) field-effect transistors (FETs) to discriminate four different types of VOCs such that isopropyl alcohol, acetone, isoprene, and toluene. Measurement results indicate our CNT FETs, utilizing the specific peptides, successfully discriminate the four different types of breath-related VOCs with high accuracy, In addition, our CNT FETs can be functionalized easily, which is another major advantage. The CNT FETs can be applied for wearable breath monitoring such as personal health diagnosis systems, and real-time human performance assessments and monitoring.    .

Speaker Bio: 
Daniel Sim is a National Research Council (NRC) Postdoctoral Research Associate working at Air Force Research Laboratory (AFRL). He has extensive experience in design, fabrication, and characterization of portable sensors & actuators and wearable devices based on N/MEMS techniques. He received the BS degree from Hanyang University, Korea, in 2009, and the M.S and Ph.D. degrees in Bio and Brain Engineering from Korea Advanced Institute of Science and Technology (KAIST), Korea, in 2011 and 2016, respectively. His research at KAIST focused on development of non-invasive skin sensors for human body monitoring. After the graduation, Dr. Sim worked on medical metrologies at Korea Research Institute of Standards and Science (KRISS). He joined Air Force Research Laboratory (AFRL) in 2018 and currently develops portable/wearable systems and design advanced device platforms to improve the performance of sensors. He was awarded with National Research Council Fellowship in 2018.
