Keynote We-K: Microscale light emitting diodes: From information display to discovery tools in neuroscience

Recent advances in materials science and engineering provide means for constructing high-performance light emitting diodes with unusual sizes, shapes and forms and with efficient operation throughout the infrared, visible and ultraviolet. When combined with high-speed assembly techniques, microscale devices of this type can be configured onto ultrathin polymer filaments for injection into biological tissues, onto elastomeric substrates for use in skin-conformal health diagnostics, and into large-scale sparse arrays for high-speed displays with unmatched brightness, contrast, switching speeds and power efficiency. This talk summarizes the foundational scientific concepts and the engineering designs for these and other applications.
