A Raman multi-gas detection system including an enhancement unit coupled between a light source and a detector. The enhancement unit includes a nanongrid having a plurality of nanogaps. A gas is coupled to the enhancement unit and is configured to flow through the plurality of nanogaps of the nanogrid. The nanogrid comprises one or more plasmon-active materials. The light source is configured to generate plasmon-enhanced electric fields in the plurality of nanogaps of the nanogrid to induce enhanced Raman scattering of the constituent molecules in the gas within the plurality of nanogaps such that a plurality of different constituent molecules in the gas can be detected. In one embodiment, a molecule in the gas is configured to scatter the light from the light source at a rate more than 1000 times greater than in the free space in the enhancement unit.

Multi-gas detection system and method

An array of movable MEMS mirror devices is provided having a high linear mirror fill factor. The array includes a base structure and selectively movable mirror structures pivotally mounted on the base structure. Each mirror structure is pivotally supported by a flexure connected to the base structure. The mirror structures each include a reflective surface portion, which is arranged in close proximity to the reflective surface portions of other mirror structures and in a generally linear alignment, forming a row structure. The flexures supporting adjacent mirror structures are staggered on opposite sides of the row structure.

Micro-electro-mechanical mirror devices having a high linear mirror fill factor

A microfluidic device adapted for use with a power source is disclosed. The device includes a substrate and a heater member. The substrate and heater member form a first portion. A second portion is formed adjacent to the first portion. The second portion includes a high activating power polymer portion, at least one resin layer and a shield member. The second portion is selectively shaped to form a thermal expansion portion. A diaphragm member encapsulates the thermal expansion portion so that when power is applied to the heater portion, the high activating power polymer expands against the diaphragm member, causing the diaphragm member to deflect. This device is adapted for use as a microactuator or a blocking microvalve.
