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.

对于动物和人类应用而言，迫切需要并且非常显著地需要微型超低压换能器来监测受限身体空间内的压力。因此，BioTechLab提出开发具有宽动态和超精细分辨率的压力传感器系统。该光纤连接压力传感器（FOLPS）基于使用激光二极管、光纤和振幅调制来感测1 mm波纹膜上的压力诱导偏转。我们的短期目标是生产和引入市场的动物应用的FOLPS。我们的长期目标是为各种动物和人类应用建立首选的压力测量系统。生物技术公司相信，FOLPS将是一个重磅炸弹的营销成功的基础上：1）预计在生物医学压力监测市场的快速两位数的增长; 2）以市场为导向的FOLPS设计;和3）技术创新的FOLPS，使强大的测量，以高稳定性和可重复性。具体而言，生物科技将在第一阶段实现以下三个目标。我：论证了利用微电子机械（MEMS）技术制造合适的微型波纹膜压力传感器的可行性。二.开发了使用激光二极管、光纤和振幅调制的光学测量系统。III：使用MatLab平台将FOLPS集成到系统中以测量实时肺功能分析。拟议的商业应用：FOLPS系统将提供动物和人类受限空间内的压力测量，用于各种应用，例如气道压力、动脉和静脉压力、颅内压力、胃肠道压力、膀胱压力等。
