My Primary Interests are in Analog, Mixed-Signal, RF and Digital VLSI Design for Sensing, Clocking, Analytics and Communication for Biomedical Applications. My broader interests include Device-Circuit co-design, Computer Architecture and Algorithms, Internet of Things, Bio-Sensors and Bio-MEMS.
Projects I’m Currently Involved in:
Medical Wearables and Implants for Closed-loop Internet of Bodies (IoB)
Funding Acknowledgement and Thanks: National Science Foundation – NSF CAREER Award ECCS #2441610
This work focuses on the design and development of Closed-loop Medical Wearables and Implants for the Internet of Bodies (IoB).
Center for Internet of Bodies: Center for IoB is a multi-university center that focuses on the research on sensing, analytics, communication, actuation, powering and harvesting around the human body.
Our vision for IoB is Explained in this Annual Review of Biomedical Engineering (2023 Impact Factor: 11.324) Article, where the challenges and opportunities in this research area are articulated, in terms of sensing, processing, communication, powering and security of IoB nodes. The specific use-cases of Human-Body Communication (HBC) are also explained for IoB, as a differentiating factor from Wireless Body-Area Network (WBAN).
More details on IoB can be found in this infographic and this blog post. Bioelectronic sensor nodes (which can be either wearable or implantable) can harness the power of distributed internet of bodies to perform closed-loop tasks such as neuromodulation. We explore fundamental challenges and limits of various energy harvesting, sensing and communication techniques that are suitable for IoB platforms. In-sensor analysis powered by efficient computing methods as well as Custom modulation techniques are also being explored.
