  • Patent number: 11938314
    Abstract: The present disclosure discusses a method of manufacturing an implantable neural electrode. The method includes cutting a metal layer to form a plurality of electrode sites, contact pads and metal traces connecting the electrode sites to the contact pads. A first silicone layer including a mesh is formed and coupled to the metal layer. A second silicone layer is formed and laminated to the first silicone layer coupled with the metal layer. Holes are formed in the first or second silicone layer exposing the contact pads and electrode sites. Wires are welded to the exposed contact pads and a third layer of silicone is overmolded over the contact pads and wires.

  • Patent number: 10791779
    Abstract: A mold for casting a micro-scale structure includes an upper surface including a first cavity having a first depth. A negative pattern for an array of micro-scale structures is defined in a surface of the first cavity. The mold includes at least one second cavity having a second depth defined in the cavity outside of the negative pattern for the array of micro-scale structures. The at least one second cavity defines a negative pattern for a standoff of the micro-scale structure. A fabric retaining frame is disposed in the first cavity.

  • Patent number: 9330944
    Abstract: An implantable bio-compatible integrated circuit device and methods for manufacture thereof are disclosed herein. The device includes a substrate having a recess. An input/output device including at least one bio-compatible electrical contact is coupled to the substrate in the recess. A layer of hermetic bio-compatible, hermetic insulator material is deposited on a portion of the input/output device. An encapsulating layer of bio-compatible material encapsulates at least a portion of the implantable device, including the input/output device. At least one bio-compatible electrical contact of the input/output device is then exposed. The encapsulating layer and the layer of bio-compatible, hermetic insulator material form a hermetic seal around the at least one exposed bio-compatible electrical contact.

  • Patent number: 7773217
    Abstract: A probe of a Raman spectroscopy system has a wavelength and/or amplitude referencing system for determining a wavelength of the excitation signal. Preferably, this referencing system is near an output aperture, through which the excitation signal is transmitted to the sample. In this way, any birefringence or polarization dependent loss (PDL) that may be introduced by optical elements in the system can be compensated for since the wavelength reference system will detect the effect or impact of these elements.
