Wearing Single-Walled Carbon Nanotube Electronics On Your Skin, Seoul National University Study

Wearable electronic systems that are integrated into our clothing, work tools or even skin patches are around the corner. In developing these flexible electronics, one of the problems that researchers have to deal with has been the use of inorganic semiconductor layers (such as silicon or gallium nitride) for the active channels and dielectric: these materials are brittle and may may easily get damaged with repetitive bending.

"Extensive research has been conducted to dissipate the induced strain in the channel and active regions, such as ultrathin thickness design approaches, neutral mechanical plane layouts, and stretchable interconnections," Ja Hoon Koo, a PhD student in Professor Dae-Hyeong Kim's Translational Flextronics Group at Seoul National University, tells Nanowerk. "More fundamental changes have been proposed to replace channel materials with soft ones, including graphene and carbon nanotubes."
