Radio frequency integrated circuits for biomedical applications

无线通信设备现在可以让我们随时随地获得信息。这项经常用于消费应用的技术可以通过保持我们与他人的联系来改善我们的生活。但在未来，无线设备也可以用来提高我们的医疗保健质量。医疗传感器可以嵌入身体、摄取或简单地放置在皮肤表面，从那里它们通过无线链路传递重要信息。研究这项技术将以更小的侵入性、更低的风险程序提供医疗保健的优势。由于嵌入式或易拆卸的传感器使用传统的电池电源往往是不切实际的，这些应用将需要创新的低功率自供电无线电。新的生物医学应用将对无线电设计提出电路和系统层面的挑战。将需要开发新的无线电体系结构以应对日益严峻的要求。此外，还需要在电路层面进行创新以实现极低尺寸和功耗要求的体系结构。因此，需要对无线电设计的各个层面的问题有广泛的理解，从设备到系统体系结构。因此，本研究项目的目标将是首先在电路和系统层面充分了解所有这些问题，然后利用这种理解来实现新的方法，允许使用无线传感器来提高所有加拿大人的医疗保健质量。

Wireless communications devices now allow us to get information anywhere anytime.  This technology, often used in consumer applications, can improve our lives by keeping us in touch with others.  In the future, wireless devices can also be used to improve the quality of our health care.  Medical sensors can be embedded in the body, ingested, or simply placed on the surface of the skin from where they relay vital information over a wireless link.  Researching this technology will provide the advantage of medical care with less invasive, lower risk procedures.  Since it is often impractical for an embedded or ingestible sensor to operate from a conventional battery power source, these applications will require innovative low power radios that are self-powered.  New biomedical applications are going to pose challenges both at the circuit and the system level for the radio design.  New radio architectures will need to be developed to handle progressively challenging requirements.  As well, innovation at the circuit level will be needed to implement architectures with extremely low size, and power requirements.  Thus, a broad understanding of issues at all levels of radio design, from device to system architecture will need to be applied.  It will be the goal of this research project to first fully understand all these issues at the circuit and system levels, and then use that understanding to realize new approaches to allow wireless sensors to be used to improve the quality of health care for all Canadians.
