Integrated Biomedical Circuits and Systems Laboratory (iBioCASL)

Welcome to iBioCASL! We are a research group in the Department of Electrical Engineering at the University of North Texas working on the design and development of low-power wearable and implantable sensors for different biomedical applications. Particularly we are interested in:

  • Wireless neural sensing and stimulation
  • Wearable sensors for vital sign monitoring
  • Implantable electrochemical sensor
  • Electro-textile antenna
  • Wireless power transfer
  • Low-power transmitter and receiver design
  • Bioimpedance measurement 
  • Analog, mixed-signal and RF integrated circuit design

Please contact Ifana Mahbub (Ifana.Mahbub@unt.edu) if you are interested to join the group!
