    Area of Science:

    • Biomaterials Science
    • Neural Engineering
    • Optical Materials

    Background:

    • Implantable neural prostheses require optically transparent encapsulation for signal transmission.
    • Cyclic olefin polymers (COPs) offer low moisture absorption and high light transmission.
    • Reliable encapsulation is crucial for the long-term function of neural devices.

    Purpose of the Study:

    • To evaluate the long-term reliability and optical performance of cyclic olefin polymer (COP) encapsulation for neural prostheses.
    • To assess the suitability of COP films for transmitting optical signals in implantable devices.
    • To determine the feasibility of using thermally laminated COP for biocompatible encapsulation.

    Main Methods:

    • Utilized film-type cyclic olefin polymers (COPs) for encapsulation via thermal lamination.
    • Conducted accelerated soak tests in 75 °C saline solution for 211 days to assess reliability.
    • Measured leakage currents from encapsulated inter-digitated electrodes to estimate device lifetime.
    • Evaluated optical properties by projecting line patterns through COP films of varying thicknesses onto an image sensor.

    Main Results:

    • COP encapsulation demonstrated an estimated lifetime of 8.05 years at 37 °C based on accelerated soak tests.
    • Light transmittance exceeded 91.69% for COP films thinner than 376 μm.
    • A minimum distinguishable line pitch of 47.6 μm was achieved with a 26 μm thick COP film.
    • COP films exhibited low moisture absorption (<0.01%).

    Conclusions:

    • Thermally laminated cyclic olefin polymers (COPs) provide a feasible solution for optically transparent encapsulation.
    • COP encapsulation meets the long-term reliability and optical transmission requirements for neural prostheses.
    • This technology supports the development of advanced implantable devices like retinal implants and optogenetic tools.
