Abstract:
　　Stretchable and wearable electronics is attracting intensive attention due to their promising applications in many areas where electronic devices undergo large deformation and/or form intimate contact with curvilinear surfaces. On the other hand, a plethora of nanomaterials with outstanding properties have emerged over the past decades. In this talk, I will summarize recent advances in stretchable and wearable electronics using a variety of one-dimensional (1D) nanomaterials, including our own work using Ag nanowires, silicon nanowires and carbon nanotubes. For such applications, the 1D nanomaterials are typically embedded or deposited on top of an elastomeric substrate (or matrix). The 1D nanomaterials possess excellent electric and mechanical properties, which make them effective in enhancing the electronic functions while not altering the mechanical stretchability and compliance of elastomer matrix. In this talk, we will highlight several device applications based on silver nanowires, including strain sensors, pressure sensors, antennas, electrodes for electrophysiological measurements and soft actuators.
