SUMMARY:ECE Research Seminar Series: Associate Professor Yei Hwan Jung\, Hanyang University
DESCRIPTION:Materials and Fabrication Strategies for Strain-Invariant Stretchable Electronics and Displays\n\n\n\n\n\n\n\nExact event time and location to be announced\n\n\n\n\n\n\n\nAbstract: Stretchable electronic systems often suffer from strain-induced performance drift\, which hinders reliable operation in practical settings. Under tensile deformation\, stretchable interconnects can lose conductivity; semiconductor devices can exhibit shifts in their current–voltage and transfer characteristics; and radio-frequency components can experience frequency detuning. Stretchable displays further face variations in fill factor and effective resolution\, which can distort rendered images and videos. Conventional stretchable touch sensors also struggle to decouple in-plane strain from out-of-plane pressure\, limiting sensing accuracy.This seminar will present recent advances toward deformation-invariant stretchable electronics and displays\, including semiconductor devices\, RF circuits\, displays\, and touch sensors that preserve their electrical and optical characteristics under elongation. I will highlight materials innovations and device-level design strategies that suppress strain sensitivity\, including strain-stable functional materials and architectures that mechanically decouple or compensate for deformation. I will also discuss design methodologies that maintain constant geometry or response under load. The talk will conclude with open challenges and future research directions toward robust\, manufacturable\, and truly strain-invariant stretchable systems. \n\n\n\nYei Hwan Jung\n\n\n\nBio: Professor Yei Hwan Jung is an Associate Professor in the Department of Electronic Engineering at Hanyang University.
