Esther Takeuchi, SUNY Distinguished Professor and Greatbatch Professor of Advanced Power Sources at the University at Buffalo, has already made her mark in the biomedical field with her signature inventions: the tiny batteries that helped make implantable cardiac defibrillators and other medical devices a life-saving reality. Now, Takeuchi is leveraging her knowledge to take up a new challenge: tackling power source issues key to developing electric vehicles. Credit: University at Buffalo
