Abstract: A variable capacitor, a microfabricated implantable pressure sensor including a variable capacitor and an inductor, and related pressure measurement and implantation methods. The inductor may have a fixed or variable inductance. A variable capacitor and pressure sensors include a flexible member that is disposed on a substrate and defines a chamber. Capacitor elements extend indirectly from the flexible member. Sufficient fluidic pressure applied to an exterior surface of the flexible member causes the flexible member to move or deform, thus causing the capacitance and/or inductance to change. Resulting changes in resonant frequency or impedance can be detected to determine pressure, e.g., intraocular pressure.

Abstract: Systems and methods for monitoring analytes in real time using integrated chromatography systems and devices. Integrated microfluidic liquid chromatography devices and systems include multiple separation columns integrated into a single substrate. Using such a device, parallel analysis of multiple samples can be performed simultaneously and/or sequential analysis of a single sample can be performed simultaneously on a single chip or substrate. The devices and systems are well suited for use in high pressure liquid chromatography (HPLC) applications. HPLC chips and devices including embedded parylene channels can be fabricated using a single mask process.
