This presentation focuses on reviewing research to develop two critical biocompatible film technologies to enable implantable biomedical devices, namely: 1) development of bioinert/biocompatible coatings for encapsulation of Si chips implantable in the human body (e.g., retinal prosthesis implantable in the human eye)-the coating involves a novel ultrananocrystalline diamond (UNCD) film or hybrid biocompatible oxide/UNCD layered films; and 2) development of biocompatible films with high-dielectric constant and microfabrication process to produce energy storage super-capacitors embedded in the microchip to achieve full miniaturization for implantation into the human bodynovel Al2O3/TiO2 nanolaminates exhibit abnormally high dielectric constant to enable super-capacitors with very high-capacitance.
本报告重点回顾了两项关键生物相容性薄膜技术的研究进展，以实现可植入生物医学设备，具体如下：1）开发用于封装可植入人体的硅芯片（如可植入人眼的视网膜假体）的生物惰性/生物相容性涂层——该涂层涉及一种新型超纳米晶金刚石（UNCD）薄膜或混合生物相容性氧化物/UNCD层状薄膜；2）开发具有高介电常数的生物相容性薄膜以及微加工工艺，以生产嵌入微芯片中的储能超级电容器，从而实现完全小型化以便植入人体——新型Al2O3/TiO2纳米层压板表现出异常高的介电常数，可实现具有非常高电容的超级电容器。
