The Proposed Program: Implantable medical devices (IMDs) are at the forefront of cutting edge research in medicine and biology, and have proved to be among the most efficient tools in curing diseases and disorders. As an example, one can name brain-implantable microsystems, as a part of the tremendous "worldwide wave of brain research" over the past decade. In harmony with the White House BRAIN Initiative in the US and the Human Brain Program in Europe, Canada has developed the Brain Canada Program, focusing on brain research in a wide sense. The proposed research program focuses on the technical challenges encountered in the development of high-rate data telemetry links to IMDs. The most challenging example of this is in high-density brain implants and visual prostheses (as a highly-advanced engineering effort towards the restoration of vision for the blind). This program aims at introducing a new approach to high-rate data telemetry to such implants by combining data compression techniques with data telemetry procedures, referred to as compressive data telemetry, hereafter. It encompasses the entire wireless telemetry path (comprising the transmitter backend, the wireless link, and the receiver front-end) as well as the realization of data compression methods. This is feasible through our background and achievements in both data compression and wireless interfacing dedicated to IMDs. The research directions in this program will include novel compressive encoding/decoding techniques, modulation/demodulation schemes, the physical telemetry link itself, and the associated implant-efficient integrated circuit implementations (taking into consideration biological tissue safety concerns when exposed to electromagnetic waves). Outcomes: According to the common terminology in digital communications, this program comprises three parts: (a) line encoding/decoding, (b) bandpass modulation/demodulation, and (c) the telemetry link itself. We will introduce novel compressive line encoding techniques that will have the property of temporal compression. Innovative bandpass modulation/demodulation schemes will then follow, which will provide the possibility of high data-rate-to-carrier-frequency ratio telemetry. This program involves the proposition of the techniques themselves, their power- and area-efficient circuit implementations, and the realization and test of the whole wireless interfacing chain. Need and Impact: Nowadays, enhancement of the capacity of IMDs such as brain implants and visual prostheses is the current mainstream of research on the development of such systems. Therefore, being equipped with effective data compression techniques as well as bit-rate efficient telemetry links is becoming a must in the development of such systems. Therefore, our research program will focus on "compressive data telemetry" as a timely effort to address this undeniable and inevitable need.

拟议的计划：可植入的医疗设备（IMD）位于医学和生物学领域的尖端研究的最前沿，被证明是治愈疾病和疾病的最有效工具之一。例如，人们可以将脑植入的微型系统命名为过去十年来巨大的“全球脑研究浪潮”的一部分。与美国和欧洲的人类脑计划的白宫脑倡议和谐相处，加拿大开发了加拿大大脑计划，重点是大脑研究。拟议的研究计划重点介绍了开发高速数据遥测链接到IMD的技术挑战。最具挑战性的例子是在高密度的大脑植入物和视觉假体中（作为为恢复盲人视力而进行的高级工程努力）。该计划旨在通过将数据压缩技术与数据遥测程序（称为压缩数据遥测方法）相结合，将高速数据遥测的新方法引入此类植入物。它涵盖了整个无线遥测路径（包括发射器后端，无线链接和接收器前端）以及数据压缩方法的实现。这是通过我们的背景和成就在数据压缩和专用于IMD的无线接口方面可行的。该程序中的研究方向将包括新颖的压缩编码/解码技术，调节/解调方案，物理遥测链路本身以及相关的植入物效率综合电路实施（考虑到生物组织安全性在暴露于电磁波时，请考虑生物组织安全问题）。结果：根据数字通信中的共同术语，该程序包括三个部分：（a）线编码/解码，（b）带通调制/解调，以及（c）遥测链接本身。我们将介绍具有时间压缩特性的新型压缩线编码技术。然后将遵循创新的带通调制/解调方案，这将提供高数据速率与载波频率比率遥测的可能性。该程序涉及技术本身的命题，其功率和区域效率电路实现以及整个无线接口链的实现和测试。需求和影响：如今，IMD（例如脑植入物和视觉假体）的能力的提高是目前有关此类系统开发的研究的主流。因此，配备有效的数据压缩技术以及比特速率有效的遥测链接正在成为此类系统开发的必要条件。因此，我们的研究计划将重点介绍“压缩数据遥测”，以及时努力解决这种不可否认和不可避免的需求。
