Non-Inductive, Ultrasound-Based Wireless Power Transfer (UWPT) for Implantable and Non-implantable Battery Charging Applications
During the first 5-10 minutes, Jared Schoepf of ASU will discuss discuss the EPICS program and volunteer opportunities for our membership; the remainder of the time, Dr. Inder Makin and Priyanka Makin will discuss biomedical applications for Ultrasound-based Wireless Powering.
This talk will present the use of ultrasound energy for wireless transfer of power through solid, liquid, gels, and related non-gaseous materials, as an alternative to the commonly used electro-magnetic (mainly inductive or capacitive) energy, remote powering schemes. Ultrasound Wireless Power Transfer (UWPT) is uniquely applicable for powering Active Implantable Medical Devices (AIMD) placed deep in the biological tissue, subcutaneous implants requiring several watts of power transfer, or where the source beam can be steered electronically using a coarse array, to correct for Source-Target misalignment. UWPT can be implemented also in the non-implantable space, such as for charging multiple digital devices simultaneously, as well as industrial applications where energy has to propagate through metal layers. The basic physical concepts determining directive beam propagation, attenuation and temperature increase will be defined. Experimental results will be presented, based on specific use-case specifications for medical (implantable) applications, as well as powering digital devices. Favorable implications of deploying UWPT for a subset of all wireless applications in lieu of the currently used power-transfer methods will be discussed.
