Autonomous biomedical devices such as cardiac and neurological implants, skin patch sensors, and automatic drug delivery pumps extend and improve life by providing therapy, monitoring, and diagnostics.   They ensure health and safety while promoting prevention and wellness.  These devices are found in chronic and acute settings that range from emergency and critical care to personalized health and telemedicine; they accelerate medical research and support data driven medicine.   The push towards the ubiquity of ever smaller devices with more functionality compels power-centric strategies in every aspect of design.  In this presentation, I will introduce new architectures in power and energy distribution and in sensing and information processing.  I will demonstrate examples from my research in neural sensing and spread spectrum power delivery as initial kernels of progressive technological directions for autonomous biomedical devices.



Al Avestruz received the SB in Physics and the SM and EE in Electrical Engineering from the Massachusetts Institute of Technology (MIT), where he is about to complete his PhD at the Laboratory for Electromagnetic and Electronic Systems. 

Through several summers with Medtronic Corporation, he researched methods and circuits to measure neural field potentials.  Al also co-founded Convergence Medical Devices, Inc. to develop and commercialize electrical impedance myography for the measurement neuromuscular disease progression.   He worked for several companies including Teradyne Corporation, Thornton, Inc. (presently a division of Mettler Toledo), Diversified Technologies, and Talking Lights, LLC before returning to MIT for graduate school.   His research interests include circuits and systems for sensing, information processing, and power conversion and distribution in biomedical and other systems.
