An electrode is provided. The electrode includes a contact pad composed of boron-doped polycrystalline diamond (BDD); a fiber core composed of BDD extending longitudinally from the contact pad from a first end that is in direct contact with the contact pad to an opposing second end; and a polycrystalline diamond (PCD) cladding that coats and hermetically seals the contact pad and the fiber core. A first portion of the contact pad and a second portion at or near the second end of the fiber core are not coated and hermetically scaled by the PCD cladding. A method of fabricating the electrode is also provided.

Implantable all diamond microelectrode and fabrication method

A pressure sensor system is provided. In another aspect, a wireless intraocular pressure sensor includes a deformable or stretchable inductor. A further aspect of an intraocular pressure sensing system includes a deformable inductor sized to contact an eye. Another aspect provides an organ pressure sending system including a passive inductor with a wavy, serpentine or undulating shape.

Intraocular pressure sensor

An implantable device is provided. The implantable device includes a flexible polymeric substrate that extends through an aperture in an electrically conductive material to form an anchor that partially covers the electrically conductive material. Methods for fabricating the implantable device are also provided.

Hybrid diamond-polymer thin film sensors and fabrication method

A neural prosthetic device can selectively deliver light to different cortical layers, at different depths, in the brain. The device includes LEDs and corresponding waveguides that can extend into the brain. At least two of the waveguides have different lengths. The neural prosthetic device or other devices can be manufactured by changing the hydrophilicity or lyophilicity of a portion of a substrate layer, then depositing uncured polymer on the treated portion of the substrate layer. The uncured polymer flows under the influence of surface tension to form a volume. The volume is shaped as a dome that extends laterally to a boundary between the treated and untreated portions. The polymer is cured in discrete regions through the substrate layer. The discrete regions extend longitudinally from the substrate layer to a curved surface of the dome. The uncured portion of the polymer is removed. The cured regions form the waveguides.
