FIBER-OPTIC-LINKED PRESSURE SENSOR

在动物和人类应用中，迫切需要一种微型超低压力传感器来监测受限的身体空间内的压力。因此，BioTechPlex建议开发这样一种具有宽动态和超精细分辨率的压力传感器系统。这种光纤连接压力传感器(FOLPS)基于使用激光二极管、光纤和幅度调制来传感1 mm波纹薄膜上的压力引起的偏转。我们的短期目标是生产FOLPS并将其推向市场，用于动物应用。我们的长期目标是建立成为各种动物和人类应用的首选压力测量系统。BioTechPlex坚信，FOLPS将取得巨大的营销成功，其基础是：1)生物医学压力监测市场预计将实现两位数的快速增长；2)以市场为导向的FOLPS设计；3)FOLPS的技术创新，使稳健的测量具有高度的稳定性和可重复性。具体地说，BioTechPlex将在第一阶段完成以下三个目标：展示使用微电子机械(MEMS)技术制造合适的微型波纹薄膜压力传感器的可行性。利用激光二极管、光纤和调幅技术研制光学测量系统。利用MATLAB平台将FOLPS集成到实时肺功能分析系统中。拟议的商业应用：FOLPS系统将在动物和人类的有限空间内提供压力测量，用于各种应用，如呼吸道压力、动静脉压力、颅内压、胃肠压力、膀胱压力等。

There is a critical need and very large marked for a miniature ultra-low pressure transducer to monitor pressure within confined body spaces for both animal and human application. Thus BioTechPlex proposes to develop such a pressure sensor system with wide dynamic and ultra fine resolution. This Fiber-Optic-Linked Pressure Sensor (FOLPS) is based on sensing the pressure-induced deflection on a 1 mm corrugated membrane using a laser diode, fiber-optics and amplitude modulation. Our short term objective is to produce and introduce into market the FOLPS for animal application. Our long term goal is to establish as the preferred pressure measurement system for a wide variety of animal and human application. BioTechPlex is convinced that the FOLPS will be a blockbuster marketing success based on: 1) the projected rapid double digit growth in the biomedical pressure monitoring market; 2) the market-oriented FOLPS design; and 3) the technological innovations of the FOLPS that enable robust measurements to be made with high stability and repeatability. Specifically, BioTechPlex will accomplish the following three objectives in Phase I. I: Demonstrate the feasibility of fabricating a suitable miniature corrugated membrane pressure sensor using Micro-Electro-Mechanical (MEMS) technologies. II. Develop the optical measurement system using laser diode, fiber-optics, and amplitude modulation. III: Integrate the FOLPS to a system to measure realtime pulmonary function analysis using the MatLab platform. PROPOSED COMMERCIAL APPLICATIONS: The FOLPS system will provide pressure measurements within confined spaces in both animals and humans for a wide variety of applications such as airway pressure, arterial and venous pressures, intra-cranial pressure, gastrointestinal pressures, bladder pressures, etc.
