I forgot to charge my AppleWatch!

Wearables, Cloud Computing, Internet-of-Things – these are the new interdisciplinary areas that will link together fields such as medicine, big data, signal processing, and HCI. However, a critical limitation to their universal adoption is power consumption. The energy-consuming microchips inside are the key, as they directly affect the cost, size, scalability, and universal adoption.

In this talk, I will describe the cross-disciplinary IC design in my E3 research group at Oregon State University that explore Energy-Efficiency at the Extremes:

• DATACENTERS: Interconnect using Optoelectronics and Silicon Photonics, collaborating with optical physicists. (funded by HP-Labs and the DOE)

• WEARABLES: Wireless Radios and RF Energy-Harvesting Sensors, collaborating with obesity dieticians and pollination scientists (funded by the USDA)


Patrick Chiang received the B.S. degree in electrical engineering and computer sciences from the University of California, Berkeley, and the M.S. and Ph.D. degrees in electrical engineering from Stanford University. He is a tenured associate professor at Oregon State University. He is the recipient of a 2010 Department of Energy Early CAREER award and a 2012 NSF-CAREER award, for energy-efficient interconnects and robust near-threshold computing. He is an associate editor of the IEEE Transactions on Biomedical Circuits and Systems, and published more than 120 conference/journal publications.
