Biofuel cell and electronics combine for disease detecting sensor

17th October 2018

Researchers, led by Subhanshu Gupta, an assistant professor in Washington State University’s School of Electrical Engineering and Computer Science, have developed a sensor which runs on a biofuel cell that harvests glucose from bodily fluids. The implantable sensor needs just a few microwatts of power to monitor biological signals and detect diseases, and could remove the need to prick a finger for testing of certain diseases like diabetes.
The biofuel cell was designed by a team led by Professors Su Ha and Alla Kostyukova from the Gene and Linda School of Chemical Engineering and Bioengineering. It is non-toxic and more stable and sensitive than conventional biofuel cells. Integrating the biofuel cell with electronics to process physiological and biochemical signals with high sensitivity is more efficient than traditional devices because it uses glucose from the body to power it.
Gupta said: “The human body carries a lot of fuel in its bodily fluids through blood glucose or lactate around the skin and mouth. Using a biofuel cell opens the door to using the body as potential fuel. This brings together the technology for making a biofuel cell with our sophisticated electronics. It’s a very good marriage that could work for many future applications.”
