Science and technology of biocompatible thin films for implantable biomedical devices

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.dielectric constant
