Wireless Power Transfer at Distance (WPT-AD) everywhere; From desktop to orbit
Professor Ali Hajimiri, California Institute of Technology, USA
Bren Professor of Electrical Engineering and Medical Engineering; Co-Director, Space-Based Solar Power Project
Abstract: Transferring significant amounts of energy using electromagnetic waves over log distances to multiple moving targets can revolutionize the nature of power generation, consumption, and storage. In this talk, we will discuss some of the recent advances in the field of WPT-AD and how dynamic RF-lensing techniques can be used to transfer power in a broad range of applications ranging from powering and charging day-to-day devices such as phones, wearables, and IoTs to transferring PV-generated power from orbit to different locations on earth in the longer term. We will discuss the roles of various technologies such as CMOS integrated circuits, flexible arrays, and intelligent algorithms in current development of such systems and demonstrate them through several actual examples.

Wireless, Battery-free Systems for Neuroscience Research, Digital Health and Interventional Cardiology
Professor John A. Rogers, Northwestern University, USA
Louis Simpson and Kimberly Querrey Professor of Materials Science and Engineering, Biomedical Engineering, and Neurological Surgery
Abstract: Advanced optoelectronic systems that can intimately integrate with soft biological tissues have the potential to accelerate progress in neuroscience research and to enable new approaches in patient care. Specifically, capabilities for interfacing electronics, light sources, photodetectors, multiplexed sensors, programmable microfluidic networks and other components into precise locations of the deep brain and for softly laminating them onto the surfaces of the skin and other vital organs create unique opportunities of wide ranging significance. This talk presents foundational concepts in wireless, battery-free approaches to these types of technologies. Examples include ‘cellular-scale’ neural probes for neuroscience research, skin-like physiological monitors for neonatal care and bioresorbable temporary pacemakers for cardiac surgical recovery.
