Bio-inspired Advanced Sensors Laboratory (BIAS) aims to realize self-contained smart microsystems that will interface people to nature, machine, and even their own bodies with many electronic devices seamlessly. The system will be implemented on a single chip platform based on modern analog and digital VLSI circuits and systems technology. We are especially interested in imaging and bio-related applications for point-of-care diagnostics, human-machine interface, and novel implantable prosthetics.
Major research field
Integrated analog-mixed signal circuit design, Semiconductor sensor interface circuits
Desired field of research
Integrated analog-mixed signal circuit design, Advanced sensor interface circuits
Research Keywords and Topics
• 3D image sensor for LiDAR systems in automotives
• Low-power biomedical sensors for point-of-care diagnostics
• Implantable/Wearable healthcare smart devices
