Abstract:

Miniaturized electronics, when placed inside the body, can wirelessly monitor and modulateinternal activity and thus hold promise as a new class of treatments for disorders. Thedevelopment of such bioelectronic medicines requires wireless interfaces that are less than a fewmillimeters in size and operate deep in a complex electromagnetic environment. In this talk, I willdescribe a new method for electromagnetic energy transfer that exploits near-field interactionswith biological tissue to wirelessly power tiny devices anywhere in the body, including the heartand the brain. I will discuss engineering and experimental challenges to realizing such interfaces,including a pacemaker that is smaller than a grain of rice and a fully internalized neuromodulationplatform. These devices can act as bioelectronic medicines, capable of precisely modulating localactivity, that may be more effective treatments than drugs, which act globally throughout thebody.

Bio:

Ada was born and raised in Hong Kong. She received her B.Eng degree from the EEEdepartment at the University of Hong Kong and her Ph.D. degree from the EECS department atthe University of California at Berkeley. Her dissertation attempted to connect information theorywith electromagnetic theory so as to better understand the fundamental limit of wireless channels.Upon graduation, she spent one year at Intel as a senior research scientist buildingreconfigurable baseband processors for flexible radios.  Afterwards, she joined her advisor’s startup company, SiBeam Inc., architecting Gigabit wireless transceivers leveraging 60-GHzCMOS and MIMO antenna systems. After two years in industries, she returned to academic andjoined the faculty of the ECE department at the University of Illinois, Urbana-Champaign. Sincethen, she has changed her research direction from wireless communications to integratedbiomedical systems. In 2008, she moved back to California and joined the faculty of theDepartment of Electrical Engineering at Stanford University. She is a Terman Fellow at StanfordUniversity. She received the Okawa Foundation Research Grant in 2010 and NSF CAREERAward in 2013.
