Three CSE researchers have won first place in the ISLPED 2010 Low Power Design Contest. The research team consists of first year graduate student Ye-Sheng Kuo, Postdoctoral Scholar Thomas Schmid, and Assistant Professor Prabal Dutta.

The team's submission, entitled "Hijacking Power and Bandwidth from the Mobile Phone's Audio Interface," was selected as the first place winner by a panel of five industry and academic experts from a field of 14 submissions. The project involves a technique for powering a new class of external peripherals by harvesting power from the headphone jacks found in smartphones.

The original prototype of hardware for the project included a separate energy harvester, microcontroller, and associated circuitry as shown in the image below. The team has since integrated the hardware into a single small PCB, shown following.

The researchers will present their project on August 20 at the International Symposium on Low Power Electronics and Design (ISLPED) in Austin, Texas.

The ISPLED Low Power Design Contest provides a forum for universities and research organizations to showcase original power-aware designs and to highlight the innovations and design choices targeted at low power. The goal is to encourage and highlight design-oriented approaches to power reduction. The International Symposium on Low Power Electronics and Design is the premier forum for presentation of recent advances in all aspects of low power design and technologies, ranging from process and circuit technologies, simulation and synthesis tools, to system level design and optimization.
