    • An implantable biocompatible electrical device is uniformly covered with a coating approximately one-micron thick of ultra-nanocrystalline diamond, hermetically sealing the electrical device. Selected electrodes are either left uncovered during coating or uncovered by conventional patterning techniques, allowing the electrodes to be exposed to living tissue and fluids. The ultra-nanocrystalline diamond coating may be doped to create electrically conductive electrodes. These approaches eliminate the need for a hermetically sealed lid or cover to protect electrical circuitry, and thus allow the device to be thinner than otherwise possible. The conformal ultra-nanocrystalline diamond coating uniformly covers the device, providing relief from sharp edges and producing a strong, uniformly thick hermetic coating around sharp edges and on high aspect-ratio parts.
    • 植入式生物相容性电气装置均匀地覆盖有大约1微米厚的超微晶金刚石的涂层,气密地密封电气装置。 所选择的电极在涂覆期间未被覆盖或者通过常规图案化技术未被覆盖,允许电极暴露于活组织和流体。 超级纳米晶体金刚石涂层可以被掺杂以产生导电电极。 这些方法消除了对密封的盖或盖的需要以保护电路,并且因此允许该装置比其它可能的更薄。 保形的超纳米晶金刚石涂层均匀地覆盖了该装置,从尖锐的边缘提供浮雕,并在尖锐的边缘和高纵横比的部分上产生强而均匀的厚的密封涂层。
