0340172This Small Business Innovation Research Phase I project will develop novel opticalpressure sensor materials that can be used in low pressure regimes, less than 100 psi, with1 psi or lower resolution. While conventional "pressure sensitive" materials such aspressure sensitive paints actually respond to oxygen partial pressure, few true opticalpressure sensors exist that can claim insensitivity to competing effects such as chemicals,bending, temperature, and electric field. Conventional sensors such as fiber Bragg gratings and fiber Fabry-Perot interferometers will continue to be prohibitively expensive for volume applications for a very long time and cannot match the price performance mark of material-based techniques.This pressure specification covers a wide range of applications where optical sensors (andFiber-optic sensors in particular) are desirable, including diverse markets such asbiomedical and surgical (e.g. intravenous and intra-cranial monitoring), energy (fuel cellsand gas turbines), materials processing (plastics and polymers), and petrochemicalapplications (down-hole temperature and pressure monitoring).

这个小企业创新研究第一阶段项目将开发新型光学压力传感器材料，可用于低压环境，小于100 psi，分辨率为1 psi或更低。虽然传统的“压敏”材料，如压敏涂料，实际上对氧分压有反应，但很少有真正的光学压力传感器能够声称对化学物质、弯曲、温度和电场等竞争效应不敏感。传统的传感器，如光纤Bragg光栅和光纤Fabry-Perot干涉仪，在很长一段时间内，对于批量应用来说仍然是昂贵的，并且无法与基于材料的技术的价格性能相匹配。该压力规范涵盖了需要光学传感器（特别是光纤传感器）的广泛应用，包括生物医学和外科（例如静脉注射和颅内监测），能源（燃料电池和燃气轮机），材料加工（塑料和聚合物）和石化应用（井下温度和压力监测）等不同市场。
