WNCG Student Hyoyoung Jeong Selected for Inaugural Engineering Ph.D. Summit
WNCG student Hyoyoung Jeong represented The University of Texas at Austin at the inaugural Engineering Ph.D. Summit in Lausanne, Switzerland. The Swiss Federal Institute of Technology in Lausanne (École polytechnique fédérale de Lausanne, or EPFL) hosted the summit, which was held November 7.
Jeong was one of 13 speakers from seven countries selected from a competitive pool of applicants to the summit. The event brings together graduating Ph.D. students making “novel research contributions.” While the field in focus this year was “Data Driven Engineering in the Life Sciences,” the summit topic is set to change every year.
Jeong shared his research in a presentation titled “Modularized Stretchable Electronic Tattoos with Wireless Power and Near-Field Communication Capabilities.”
Electronic tattoos, or “e-tattoos,” are “noninvasive, soft, and multifunctional” electronics that are applied to the skin. Applications of this technology could potentially benefit a variety of fields, including healthcare, activity tracking, and human-machine interface. Jeong’s research led to his development of a more cost- and time-effective fabrication process, which he refers to as “cut-solder-paste.”
The new process allows the thin film of the e-tattoos to be cut using freeform patterning. The goal is to make wireless power and data transfer possible via near field communication (NFC).
“I was able to demonstrate a modular design multilayered NFC e-tattoo,” Jeong states in his paper abstract. “Such NFC e-tattoos are stretchable up to 20% and capable of wireless real-time monitoring of [various vital signs] … The combination of a rapid, freeform manufacturing process and the modular design establishes a new era for personalized wearable soft bioelectronics.”
Jeong is advised by Dr. Nanshu Lu, whose group recently joined WNCG this fall.

Hyoyoung Jeong received his B.S. in 2008 from Yonsei University with high honors, and M.S. from Seoul National University in 2010. He worked as a developer and researcher at Samsung Electronics (Mobile Communication Division) and Samsung Advanced Institute of Technology for almost 5 years.
He is currently a 5th year Ph.D. student in the Biomedical Engineering Track of the Electrical and Computer Engineering (ECE) program at the University of Texas at Austin. His research is focused on wireless stretchable electronic tattoo (E-tattoo) sensors for mobile healthcare monitoring. He has originated modular and reconfigurable E-tattoo strategy for the battery-free operation of wireless E-tattoos based on near field communication (NFC) and Bluetooth (BT) technology. He has published 9 journal papers, 23 conference papers. He also holds 16 patents with 10 pending applications in his research field.
