Connected devices and weArables lab

Principal Investigator: Dr. Kurian Polachan, Senior Member IEEE

Our group focuses on researching and prototyping hardware and systems for connected devices and wearables, with applications in healthcare, consumer electronics, and industrial IoT.

Specific Research Interests

Engineering Wearables: Developing ultra-low-power, rigid and flexible wearable devices for health monitoring, supporting on-device machine learning algorithms for anomaly detection, secure short-range communication technologies and PUF-based hardware security measures.

Hardware Security: Developing Physical Unclonable Function (PUF)-based security measures to protect wearable devices from unauthorized access or replacement (e.g., PUFs for wearables).

Tiny-ML: Application of tiny machine learning for resource constrained edge devices such as MCU-based embedded systems. E.g., on-device abnormality detection of vital signs for healthcare applications.

Short-Range Secure Communication: Explore different modalities of secure and ultra-low-power short-range communication between wearables and off-body transceivers. (e.g., visible light communication, human body communication)
