A Low Power Wireless Pulse Oximeter Sensor for Unobtrusive Wearable Applications

项目总结/摘要 Koronis生物医学技术公司（KBT）建议开发和评估一种微型超低 用于长期可穿戴监测的功率脉搏血氧仪。临床上仍然需要一种 一种不显眼的脉搏血氧仪传感器，体积小，可长时间舒适地佩戴 无需更换电池或充电。KBT将使用人眼安全的垂直腔面发射激光器（VCSEL） 技术来开发下一代尖端脉搏血氧仪。一些技术挑战必须 以便于长期连续的脉搏血氧饱和度监测。为了设计得更紧凑 传感器和改进的可穿戴仪器，也许最关键的挑战是开发更多的 功率效率高且重量轻的设备。此外，在可穿戴设备可以有效地用于 在家中，它们必须不引人注目，不应妨碍一个人的行动。标准指脉 血氧计对于许多应用是不实用的，因为它们可能干扰正常的日常任务。

Project Summary/Abstract Koronis Biomedical Technology Corporation (KBT) proposes to develop and evaluate a miniature ultra-low power pulse oximeter for long-term wearable monitoring. There continues to be a clinical need for an unobtrusive pulse oximeter sensor that is small and can be worn comfortably for extended periods of time without battery change or recharge. KBT will use eye-safe Vertical Cavity Surface Emitting Laser (VCSEL) technology to develop this next generation, cutting-edge pulse oximeter. Several technical challenges must be overcome to facilitate long-term continuous pulse oximetry monitoring. In order to design more compact sensors and improved wearable instrumentation, perhaps the most critical challenges are to develop more power efficient and low-weight devices. Additionally, before wearable devices can be used effectively in the home, they must become unobtrusive and should not hinder a person's mobility. Standard finger pulse oximeters are not practical for many applications because they can interfere with normal daily tasks.
