OBJECTIVE We focus on improving the long-term stability and functionality of neural interfaces for chronic implantation by using bilayer encapsulation. APPROACH We evaluated the long-term reliability of Utah electrode array (UEA) based neural interfaces encapsulated by 52 nm of atomic layer deposited Al2O3 and 6 µm of Parylene C bilayer, and compared these to devices with the baseline Parylene-only encapsulation. Three variants of arrays including wired, wireless, and active UEAs were used to… CONTINUE READING
