‘Nanowire’ is a general term defining wire structures about 100-100,000 times smaller than human hair. When materials shrink into such small sizes, new properties can come about. In this talk, I will describe how we can effectively manipulate these ultra-small wires in a controlled way, not only in a 2D plane for new circuit application, but also in 3D forms for novel bio-sensing. I will further broaden this ‘nanowire’ concept into some naturally produced bio-nanowires that may possess surprising electronic properties, and hence brings in potential in creating a better interface for future human-friendly wearable and biomedical technologies.
Jun Yao is trained as an interdisciplinary researcher experienced and interested in developing novel nanodevices, sensors, and their integration in/on non-conventional soft-material scaffolds for wearable and smart systems/materials. For example, his latest research involved developing ‘syringe-injectable electronics’, where the ultra-flexible, mesh-form and porous electronics can be squeezed, loaded and ejected through a syringe needle to enable surgery-friendly and intimate electro-brain interface. This is an example entails his vision that future electronics may well evolve into real 3D, soft, and biomimetic systems. Before the joint position between the ECE Department and Institute for Applied Life Sciences at Umass Amherst, he was a Harvard postdoctoral fellow focusing on the synthesis, assembly, fabrication and integration of nanomaterials for electronic and bioelectronic applications. He received his Ph.D. in Applied Physics from Rice University, where he lead the discovery of the intrinsic memristive effect in silicon oxides and the implementation in memory device and commercialization. He holds a B.S. in Electrical Engineering and an M.S. in Physics from Fudan University in China.
