Integrated Nanowire Electronics and Sensors on Flexible Plastic Substrates
Thu, Nov 15, 2007 @ 12:45 PM
Mork Family Department of Chemical Engineering and Materials Science
Conferences, Lectures, & Seminars
Graduate SeminarbyDr. Michael McAlpine
Post-Doctoral Researcher
Division of Chemistry and Chemical Engineering
California Institute of TechnologyAbstractThe introduction of an ambient-temperature route for integrating high performance materials on
flexible plastic substrates could enable exciting avenues in fundamental research, and innovative
electronic and medical devices. However, the temperature constraints imposed by these substrates
restrict the use of high carrier mobility materials, such as polycrystalline silicon, generally limiting these devices to the modest computational capabilities of amorphous silicon and organic semiconductor thin film transistors. The development of new materials and novel materials processes for overcoming this restriction could impact a broad spectrum of applications.Semiconductor nanowires represent unique, high performance building blocks for electronic,
photonic, and sensing devices. In this talk, I will present my work demonstrating that single-crystal
nanowires can be hierarchically assembled onto flexible plastic substrates under ambient conditions to create multi-component, fully integrated devices, including field-effect transistors, light-emitting diodes, ring oscillators, and electronic noses. These devices all exhibit performance metrics which meet or exceed the state-of-the-art for flexible electronics.The key to our approach is the separation of the high-temperature synthesis of single-crystal
nanowires from room temperature assembly, thus enabling fabrication of high-performance devices on
virtually any substrate. Silicon nanowire field-effect transistors on plastic substrates display mobilities rivaling those of single-crystal silicon and exceeding those of amorphous silicon and organic transistors currently used for plastic electronics. Furthermore, we show that these systems can be integrated into ring oscillators on plastic which generate frequencies approaching the microwave, the highest observed frequencies for circuits based on nanoscale materials.Finally, we exploit SiO2 surface chemistries to construct a "nano-electronic nose" library,
which can distinguish acetone and hexane vapours via distributed responses. We also demonstrate that
amide coupling of theoretically tailored peptide sequences to the arrays allows for selective
discrimination of chemicals often found in the breath of sick patients. This excellent sensing
performance coupled with biocompatible plastic could open up far-reaching opportunities in mobile
computing, lightweight display, or even implantable monitoring applications.Thursday, November 15, 2007

CS Colloquia: Robotic Planetary Science: the Mars Exploration Rovers and Beyond
Thu, Nov 15, 2007 @ 04:00 PM - 05:30 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Title: Robotic Planetary Science: the Mars Exploration Rovers and BeyondSpeaker: Dr. Ashley Stroupe(JPL)ABSTRACT:
This talk will present the present and future of robotic Mars exploration,
including the current Mars missions and system prototypes for future missions
to the Moon and Mars. The talk will begin with an overview of the the Mars
Exploration Rovers, Spirit and Opportunity, which have been exploring Mars for
nearly 4 years. We will focus on autonomous rover capabilities, highlights of
mission science discoveries, and lessons learned. Following, there will be a
brief discussion of the next Mars missions, Phoenix and Mars Science
Laboratory. We will conclude by looking at some prototypes for future
missions, including Lunar exploration (with Athlete) and difficult terrain
exploration (with TRESSA).BIO:
Ashley W. Stroupe is a staff engineer at Jet Propulsion Laboratory in
Pasadena, California. She works as a rover driver with the Mars
Exploration Rover Project, building sequences of commands to drive the rover
and deploy science instruments. Dr. Stroupe does research focusing on
multi-robot teams in complex environments and behavior-based control, with
applications to exploration and mapping, dynamic target observation, and
cooperative manipulation. She has published multiple conference papers, book
chapters, and journal articles in robotics and is an active participant in
multiple education and outreach programs. She received a B.S. in physics from
Harvey Mudd College in 1990, an M.S. in electrical engineering from George
Mason University in 1998, an M.S. in robotics from Carnegie Mellon University
in 2001, and a Ph.D. in robotics from Carnegie Mellon University in 2003.Location: Seaver Science Library (SSL) - 150

ASBMEs 6th General Meeting
Thu, Nov 15, 2007 @ 05:00 PM - 06:00 PM
Viterbi School of Engineering Student Organizations
Student Activity
Hey fellow BMErs! For our upcoming event next Thursday, we will be meeting with two of USC's distinguished research professors as they come to share with you about their respective fields of research! Among the topics of research, our speakers will be talking about Craniofacial and Dental Technology, so you will NOT want to miss out!Guest Speaker Bios:
Dr. Jean- Michel Maaerk is the director of the Medical Devices and Diagnostic Engineering Program. So for those of you interested in pursuing a career in fields such as clinical research or cardiovascular devices, come out to the meeting for the chance to discuss or ask questions about Maaerk's project! Dr. Reyes Enciso is a research professor at the USC clinical School of Dentistry. Beginning this fall, Viterbi will be introducing a new minor in Craniofacial and Dental Technology, an interdisciplinary collaboration between the School of Dentistry, the BME department in Viterbi, and the department of Biological Sciences. So for all of you BMEr's who are going into dentistry or are curious about engineering the mouth, you will NOT want to miss out on this either! As always, dinner will be provided! We will be serving Italian Vistangos! HOPE TO SEE YOU THERE!!Location: Seeley G. Mudd Building (SGM) - 601
