Tiny battery-less RFID-scale sensing devices are poised to transform science and society by enabling long-term maintenance-free data gathering, but system designers currently lack the hardware platforms, abstractions, languages, and tools needed to harness this potential. Replacing batteries with capacitors has many advantages for system designers (smaller size, lower cost, and the potential for decade-long deployments—batteries wear out after 2–5 years), but even with energy harvesting advances, current capacitor-based devices (Computational RFIDs, EnHANTs) are difficult to program, test, and deploy, due to unpredictable energy supplies, limited energy storage, and frequent power failures.
This talk will describe hardware and software techniques for building tiny sensing systems that depend on harvested energy, can be deployed for long periods of time without battery changes, and are able to adapt to uncertain energy conditions and thrive in spite of frequent power failures.



Jacob Sorber is an Assistant Professor in Clemson University's School of Computing. His research makes mobile sensors, sensor networks, and embedded systems more efficient, robust, deployable, and secure, by exploring novel systems (both hardware and software) and languages. Before joining the Clemson faculty, he was a postdoctoral researcher at Dartmouth College. He received his M.S. and Ph.D. degrees from the University of Massachusetts Amherst in 2009, and a B.S. degree from Brigham Young University.
