Researchers at University of Arizona have developed a device used to study the link between brain behavior and vocalization. Using new methods of antenna design and optimized electronics, Jokubas Ausra, a biomedical engineering doctoral student in the lab of BIO5 member Dr. Philpp Gutruf, was able to shrink the devices dramatically compared to existing versions, to about a third of the size of a dime and as thin as a sheet of paper. Co-senior author on the study and also a BIO5 member, Dr. Julie Miller, is helping the team with the goal to expand device capabilities to also record neuron activity.
