Energy Efficient System Architecture for Self-Powered Wireless Biomedical Sensors in Health IoT Applications


More than half of deaths worldwide are due to the top 10 causes, such as ischemic heart disease, stroke, chronic obstructive pulmonary disease, etc. Huge money pours into platforms to support disease management. Wireless biosensors are one of such platforms, with their ability to measure and communicate parameters that indicate the presence, or onset, of pathology. The global mobile health market is poised to grow at a CAGR of around 32.3% over the next decade to reach approximately $189 billion by 2025. This is an explosive trajectory, yet the development of wireless wearable sensors faces huge challenges. So far there are no satisfactory solutions for reliable real-time monitoring of vital signs such as blood pressure and electrocardiogram (ECG), not to mention other important parameters such as cardiac output, vessel level flow, or drug levels to name but a few. This talk will cover opportunities and challenges in the development of wearable wireless biomedical sensors. The focus is on the energy efficient system architecture that utilizes the continuous-in-time and discrete-in-amplitude (CTDA) signal flow. The CTDA signal flow enables data compression at the input source, which greatly reduces the power for wireless data transmission. Design examples, such as 2.89μW wireless ECG SoC, will be discussed in detail to illustrate the benefits of CTDA system architecture.
