Modeling Stretchable Electronics for Wearables
Through a highly interesting and fruitful collaboration with the experimental group of Professor Zhenan Bao in Chemical Engineering and the experimental group of Professor Yi Cui in Material Science, as well as other collaborators within Stanford, a project on the creation of stretchable electronics for applications in the field of wearable devices, funded by Samsung, a number of interesting mechanical observations and findings were made. We looked at nanoconfinement effects in blend polymer systems, were able to understand the microstructural origin of resistance-strain hysteresis in carbon nanotube thin film conductors, modeled 3D conducting polymer foams, and helped develop stretchable transistors, circuits, and semiconductors.
