Parylene Photonic Microimager for Implantable Imaging

We have recently introduced a fully flexible, compact photonic platform, Parylene photonics. Here, we demonstrate a Parylene photonic waveguide array microimager with a light source localization accuracy of 17.04 µm along the x-axis and 30.07 µm along the y-axis over a 200 µm×1000 µm region. We show the feasibility of fluorescent imaging from mouse brain tissue using the microimager array.Clinical Relevance— Implantable microimagers can be used for clinical intraoperative monitoring as well as structural and functional imaging with cell-type specificity in research.
