摘要

A new technique for the fabrication of arrayed waveguide gratings on upconversion luminescent layers for flexible transparent displays is reported. Ho3+- and Yb3+-codoped NaYF4 nanoparticles are synthesized by hydrothermal techniques. Transparent films consisting of two transparent polymers on the NaYF4 nanoparticle films exhibit mechanical flexibility and high transparence in visible region. Patterned NaYF4 nanoparticle films are fabricated by calcination-free micromolding in capillaries. Array

How to achieve sub-cellular-level spatial resolution and sub-spike-level temporal resolution at same time is still a technical challenge in neural mapping while both information are critically important to advance neural science. Here, we present penetrating arrays consisted of single-neuron level transparent microelectrodes with low impedance coating which could realize the high spatial and temporal resolution at the same time. These 32-channel transparent penetrating electrodes with record-small site area, 225 µm², have a low impedance of ~ 149 kΩ at 1 kHz, an adequate charge injection limit of ± 0.76 mC/cm2, and up to 100 yield. Mechanical bending test result show robust mechanism up to 1000 bending cycles. After a temporary stiffen with polyethylene glycol, this electrode achieved great insertion result without any buckling or deformation. Together these results establish a novel neurotechnology - penetrating arrays of transparent, flexible bilayernanomeshMicroelectrodes which possess great potential for brain research [O] .
