Abstract :
We present the design, simulation, fabrication, and characterization of a novel flexible optrode for deep brain light delivery and collection. The optrode has an annular cross-section for light guiding consisting of a transparent polymer in combination with ultra thin glass, and is fabricated by a unique process we developed: V-groove guided capillary assembly. The optrode design addresses a major limitation on the length-to-diameter ratio. In addition, the optrode can provide crack-free operation during tissue insertion and/or prolonged studies.
