About

Our research group applies principles of engineering and physics to the design of new types of medical electronic, ultrasonic, and optical instrumentation.

Our research  supports development of bionic neuroprostheses needed in both the study of the human brain and in the design of devices which allow direct man-machine connections. We are specifically interested in the design of microminiature neurostimulation devices that are appropriate for healthcare such as in the treatment of neurological  injuries and debilitating disorders such as Parkinson’s, epilepsy and other bioelectrical disorders.

Our research employs the use of wireless transmitting microscale bioelectrical devices some of which are comparable to the sizes of  common syringe needle lumens and so allow injection into the body without surgery and with minimal trauma.

Recent researches have concerned nano-molecular scale interactions of electrical and optical energies with the nervous system. We are interested in the potential for noninvasive neurostimulation by employing ultrasonic, microwave, and optical  forces to membranes of neural cells

We are investigating the application of ultrasound energy to the design of noninvasive bionic neural prostheses for rehabilitative medicine and in the study of how ultrasound energy interacts with the nervous system.  Current interests are also in the design and development of microscale implantable biochemical sensors and telemetry systems that allow wireless communication.

We foster collaborations with neurosurgeons at the Barrow Neurological Institute and with radiology at Mayo Clinic Scottsdale.  Ongoing projects are in support of the goals of the ASU Nanophotonics Center in electrical engineering, wireless microscale telemetry with ASU WinTech.   Presently there are two NIH R21 grants and an NSF grant supporting work in the lab.

Support for the lab has been from  NASA, NIH, NSF, Whitaker Foundation, Flinn Foundation, American Heart Association, Arizona Disease Control Research Commission. Our work is primarily conducted in the ASU Bioinstrumentation and Biosensors Laboratory in ECC-115.
