Workshop on Biomedical Radars and Circuits
Microwave biomedical radar has recently emerged as a highly promising sensing technology. Utilizing radio-frequency electromagnetic waves, it enables non-invasive and non-contact detection and monitoring of physiological signals and vital signs such as respiration, heartbeat, and body movement. When properly leveraged, it can serve as a powerful tool across various applications including elderly care, sleep analysis, clinical monitoring, and behavioral analysis. The design and implementation of its circuits, systems, and algorithms present significant challenges. In this workshop, we are honored to invite five distinguished researchers in the field of microwave biomedical radars and circuits to share their valuable insights and research achievements with us.

Challenges in Experiment Design for Microwave Biomedical Applications
In research, it is a must to validate ideas by realistic proofs-of-concept (PoCs). The difficulty of conceiving experiment design is finding the optimal balance between time efficiency, cost, and effectiveness. Microwave engineering is characterized by a high dimensionality in experimental degrees of freedom, such as selecting among a wide choice in measurement instrumentation. The level of difficulty increases even more when the subjects are to advance the health of the community at large. This talk discusses the challenges that microwave engineers face when developing experimental set-ups targeting tests for microwave biomedical applications. The talk covers multiple emerging areas within this domain, ranging from in-vivo dielectric spectroscopy, characterizing liquids in vials, high-precision sensing of small concentrations, to vital sign dynamic sensing and ensuring exposure safety.

A New Gain Increasing Method Near fmax by Effectively Managing Voltage Distribution on the Gate Finger
Amplifiers operating in milli-meter wave and sub-THz are attracting a lot of attentions for various kinds of applications, such as sensors and communications. However, the maximum gain ability of an FET is sometimes not high enough in those frequency regions. Shorter gate length transistor increases the gain but there would be a limit to miniaturization and the process cost is high for those technologies. In this presentation, a unique method to increase gain without any process change will be introduced. The method is the standing-wave controlled gate which can increase not only near fmax but also fmax itself.

A Few Inspiring Tales from the World of Biomedical Radar
By utilizing microwave signals to sense various life activities, portable radar systems equipped with advanced front-end technologies and sophisticated measurement algorithms have immense potential to revolutionize healthcare, security, and human-machine interfaces. This presentation will begin with an overview of the history of biomedical radar and explore case studies at the cutting edge of the human-microwave frontier. Topics will include physiological signal sensing, non-contact human-computer interfaces, driving behavior recognition, human tracking, and applications in clinical environments. Drawing from the presenter’s personal experience as well as involvement in the MTT-28 Microwave Biological Effects and Medical Applications Committee, the presentation will highlight the inspiring stories and career journeys of several researchers in the field. The aim is to motivate and encourage more engineers and scientists to engage in microwave research and development, fostering innovation in this transformative domain.

Physiological Radar for Biomedical and Smart Building Applications
Doppler radar technology can measure human physiological activity for a wide range of biomedical needs. Compact economical radar systems have been demonstrated as a non-invasive means of measuring vital signs through clothing and bedding, including heart and respiratory rates and signatures, activity, sleep posture, tidal respiratory volume, and pulse pressure. The value of such physiological monitoring extends beyond healthcare for applications including search and rescue, secure authentication, and smart buildings. This talk will provide an overview of state of the art in Doppler radar physiological monitoring and related applications.
