About Roseanne Warren
Dr. Roseanne Warren is an Associate Professor in the Department of Mechanical Engineering at the University of Utah. She received her PhD in ME from UC Berkeley (2015), where she spent her time in the Marvell Nanofabrication Laboratory making things that sometimes worked. Dr. Warren’s current research interests lie at the intersection of nanofabrication, electrochemistry, and nanoscale mechanics testing.
Thermal Self-Charging Power Cell: Integrating Energy Harvesting and Storage at the Materials Level
Battery R&D is an exciting field for mechanical engineers. From materials development to mechanical testing to new device functionalities including self-charging power cells , there are many avenues of exploration. This talk will introduce a new device concept for a self-charging power cell developed by University of Utah mechanical engineers that we call a “pyroelectrochemical cell” (PEC). The PEC integrates a pyroelectric material inside an electrochemical cell to achieve direct conversion of ambient thermal energy to stored electrochemical energy. Methods of probing PEC device physics through experiment, finite element simulations, and lumped parameter modeling will be presented, along with potential applications of the PEC in Internet of Things remote sensing.
