2019 Engineering Awards: Deadline for Nominations Engineering Awards: Deadline for Nominations2018-12-17T06:00:00Z<p>​The 2019 Engineering Awards will be presented at the annual ceremony on Thursday, April 25, 2019. </p><p>The Engineering Awards Program recognizes alumni whose achievements have been truly outstanding. Since 1975, the <a href="/Pages/home.aspx">School of Engineering & Applied Science</a> has acknowledged the exceptional accomplishments of our distinguished alumni through this most important honor. A list of past honorees can be found on the <a href="/alumni/programs-events/alumni-achievement-awards/Pages/default.aspx">School of Engineering & Applied Science website</a>.</p><p>In addition to career achievements, the selection committee will review contributions to education, civic causes, professional societies, and public service to support the three nominated honors: Alumni Achievement Award, Young Alumni Award, and Engineering Entrepreneurship Award. Engineering alumni have varied careers, and because of this consideration is not restricted to those who have followed a traditional engineering career path.</p><p>Please consider nominating an appropriate candidate  by providing detailed information in the <a href="">online nomination form</a>. The deadline for submission is Dec. 17.<br/></p><p> Contact the Engineering Alumni & Development office at 314-935-8273 or <a href=""></a> with any questions.<br/> </p>
CSE Doctoral Dissertation Defense: Kenji Aono Doctoral Dissertation Defense: Kenji Aono2018-12-19T06:00:00Z1 p.m.3 p.m.Jolley Hall, Room 309<p rtenodeid="5"><strong>​"Nanopower Analog Frontends for Cyber-Physical Systems"</strong><br rtenodeid="6"/></p><p><strong>Kenji Aono</strong><br/>Adviser: Shantanu Chakrabartty<br/></p><div>In a world that is increasingly dominated by advances made in digital systems, this work will explore the exploiting of naturally occurring physical phenomenon to pave the way towards a self-powered sensor for Cyber-Physical Systems (CPS). In general, a sensor frontend can be broken up into a handful of basic stages: transduction, filtering, energy conversion, measurement, and interfacing. One analog artifact that was investigated for filtering was the physical phenomenon of hysteresis induced in current-mode biquads driven near or at their saturation limit. Known as jump resonance, this analog construct facilitates a higher quality factor to be brought about without resorting to the addition of multiple stages and poles in the filter. </div><div><br/></div><div>Exploiting this allows a filter that mimics mammalian cochlea using \SI{}{\nano\W} of power, and the viability of using such a filter was demonstrated in the application of speaker recognition. Features were extracted using a silicon cochlea analog frontend, which outperformed features from traditional linear filters when classification was done with a Gini-SVM.</div><div><br/></div><div>To realize the measurement stage of the frontend, a previously reported technology, the Piezoelectric-Floating-Gate (PFG) was employed. The PFG matches physics of Impact-Ionized Hot-Electron Injection (IIHEI) in silicon metal-oxide field effect transistors with a piezoelectric transducer to drive nonvolatile data-logging measurements. The PFG implementation is self-powered in the sense that the energy required for sensing comes from the signal being observed, which allows for continuous, zero-downtime measurements of signals that exceed the IIHEI threshold and can drive \SI{}{\nano\W} loads. Moreover, since it directly matches the transduction stage to measurement, it obviates the need for an explicit energy conversion stage in the frontend. Multiple interfacing technologies were evaluated, including: wired, self-powered radio-frequency (RF) backscatter, periodic \SI{915}{\mega\hertz} active RF, and a hybrid model that uses energy scavenging to determine if an interrogator is within range before transmitting. A multi-year deployment of this sensor frontend for structural health monitoring is currently active on the Mackinac Bridge in northern Michigan and demonstrates successful transition from laboratory to practice for a CPS.</div><div><br/></div><div>Finally, a modification to the PFG topology to include filtering aspects borrowed from earlier study was proposed and fabricated on a standard \SI{0.5}{\micro\meter} CMOS process. Measurements show that the PFG sensor can be endowed with frequency discriminating capabilities to better focus on signals of interest. The modifications also give rise to a means for higher sensitivity (input stimuli below IIHEI threshold) data-logging that would vastly expand the potential application space.<br/></div><p><br/></p>
