    摘要： Intraocular retinal prosthesis systems and methods for fabricating the same are provided. In one aspect, fabrication of all or multiple components of a prosthesis device or system are combined into a single monolithic fabrication process. Also, many such entire systems can be fabricated simultaneously in a single microfabrication processing run. A prosthesis device includes a cable region that connects an electrode array region with a power and data management region. The electrode array region includes one or more arrays of exposed electrodes, and the power and data management region includes various power and control elements. The power and data management elements, in one aspect, include an RF coil or coils and circuit arrangements and/or chips configured to provide drive signals to the electrodes via a cable and receive power and signals from the RF coil or coils. Each region includes elements fabricated on or in a single polymer layer during the same fabrication process.

    摘要： A biocompatible, mechanical, micromachined pressure sensor and methods of manufacturing such a pressure sensor are provided. The pressure sensor of the current invention comprises a high-aspect-ratio curved-tube structure fabricated through a one-layer parylene process. The pressure sensor of the current invention requires zero power consumption and indicates the pressure variation by changes of the in situ in-plane motion of the sensor, which can be gauged externally by a direct and convenient optical observation. In one embodiment, the pressure sensor of the current invention has been shown to work as an IOP sensor for eye implantation where the intraocular in-plane motion of the sensor can be recorded from outside of the eye, such that the intraocular pressure in glaucoma patients can be constantly monitored.

    摘要： Micro check valves having a free-floating member for controlling flow of fluid in microfluidic and biomedical applications and methods of fabrication. A micro check valve includes a valve seat, a valve cap that contacts the valve seat and an untethered floating member that can move between the valve seat and the valve cap. Certain micro check valves have zero cracking pressure and no reverse leakage. Certain other valves may be configured to permit flow of fluid within a pressure range. The floating member can be solid or define an orifice, and the valve seat can have one or two levels. Valves can be configured to allow fluid to flow when the floating member is pushed by fluid against the valve cap or against the valve seat. The valve seat may be silicon or another material that is compatible with micromachining processes, and the valve cap and the floating member may be a polymer such as Parylene.
