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! 

Upcoming Conferences:

Congratulation to Dr. Russel Reid and Dr. Ifana Mahbub for their journal on "Wearable Self-Powered Biosensors" in the Current Opinion in Electrochemistry, Elsevier Journal.

IBioCASL lab participated in an interdisciplinary STEM (i-stem) camp for Navy Junior ROTC high-school students as a part of the Office of Naval Research Grant (PI: Kaul, co-PI: Mahbub). In this camp, the students will have had the opportunity to explore state-of-the-art technologies for wireless power transfer and data telemetry systems. Students observed how an experimental mouse cage can be wirelessly powered using resonators to power the LED on a headstage made for freely-moving animals such as mice or rats. The students also had the opportunity to make a dipole antenna and characterize their fabricated antenna’s performance. (11/07/19)
