BSAC Seminar: Interfacial Engineering in MEMS: Handling and Assembly of Solids and Liquids at the Microscale

May 11, 2010
Prof. Karl Bohringer Departments of Electrical Engineering and Bioengineering, University of Washington BSAC PostDoc 1995 May 11, 2010 | 12:00 to 01:00 | 521 Cory Hall, Hogan Room Host: Al Pisano

A well-known outcome of down-scaling into micrometer dimensions is the dominance of surface over bulk phenomena. When designing micro-scale systems, the ability to understand and modify surface properties is of utmost importance. A key concept is the "programmable surface" - an interface whose properties can be controlled with high spatial and temporal resolution. This...

BSAC Seminar: The Infrared Retina: Moving Towards the Fourth Generation Infrared Detectors with Quantum Dots and Superlattices

June 16, 2010
Prof. Sanjay Krishna Department of Electrical and Computer Engineering, University of New Mexico June 16, 2010 | 01:00 to 02:00 | 521 Cory Hall, Hogan Room Host: Ali Javey

Infrared detectors operating in the 3-20um are important due to three primary reasons: First, the atmosphere is transparent in the two bands referred to as mid-wave infrared (MWIR, 3-5um) and long-wave infrared (8-12um), making it possible to see through fog and smoke under poor visibility conditions. Second, a lot of chemical species have characteristic absorption features in this wavelength range...

BSAC Seminar: Developing Subcutaneous Fully-Implanted Biochips for Remote Monitoring of Human Metabolism

July 15, 2010
Prof. Sandro Carrara Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland July 15, 2010 | 11:00 to 12:00 | 521 Cory Hall, Hogan Room Host: Ming Wu

The aim of this talk is to present an innovative concept for multi-metabolites, highly integrated, fully implantable, and real-time monitoring systems for human metabolism. On-line monitoring for diagnosis and/or treatment of patients with specific physiological conditions (e.g., heart, cardiovascular, cancer) or convalescents is a key factor to provide better, more rational, effective and ultimately...

BSAC Seminar: Magnetic Levitation for Micromanipulation

June 17, 2010
Prof. Behrad Khamesee Department of Mechanical and Mechatronics Engineering, University of Waterloo, Canada June 17, 2010 | 11:00 to 12:00 | 540 Cory Hall, DOP Center Conference Room Host: Richard Lossing

In this talk, a novel technique for micromanipulation using magnetic levitation is presented. The design and development of a microrobotic system based on magnetic principles is described. The goal is to develop a system in which miniature items can be transported and assembled within hazardous environments. A teleoperated microrobot is levitated and moved within a...

BSAC Seminar: Devices, Circuits, and Signal Conditioning for Electrostatic MEMS in CMOS Technology

August 10, 2010
Prof. Jordi Madrenas BSAC Visiting Scholar from the Technical University of Catalunya, Spain, Advanced Hardware Architectures Group August 10, 2010 | 01:00 to 02:00 | 521 Cory Hall, Hogan Room Host: Liwei Lin

The recent research work on mixed-signal conducted by the Advanced Hardware Architectures Group of the Technical University of Catalunya (Barcelona) is presented. At the device level, electrostatic actuators that use standard CMOS interconnection metal layers as structural elements and the insulating silicon dioxide as sacrificial layers have been...

BSAC Seminar: Berkeley Biomolecular Nanotechnology Center & User Garage

September 21, 2010
Dr. Paul Lum Director, UC Berkeley, QB3 Institute, BNC September 21, 2010 | 12:30 to 01:30 | 540 Cory Hall, DOP Center Conference Room Host: John Huggins

The goal of the Biomolecular Nanotechnology Center is to foster interdisciplinary collaboration across the UC Berkeley campus and the broader academic and industrial community in order to design, fabricate, and evaluate micro- and nano-scale devices for medicine and biology. To that end, the center aims to: Combine facilities for CAD, modeling, fabrication, analysis, and...

BSAC Seminar: Printing Energy Storage Devices

September 28, 2010
Dr. Christine Ho Postdoctoral Researcher, UCB Center for Entrepreneurship and Technology September 28, 2010 | 12:30 to 01:30 | 540 Cory Hall, DOP Center Conference Room Host: John Huggins

As electronic devices become smaller in volume and more specialized in functionality, a paradigm shift in energy storage design and manufacture is beginning to emerge and can be realized with the development of simple, low-cost, solutions-based processing methods to incorporate custom energy buffers directly onto a device. I will discuss the motivations and implications...

BSAC Seminar: Harvesting Energy from Energized Conductors

October 5, 2010
Dr. Igor Paprotny Department of Electrical Engineering and Computer Sciences, UC Berkeley BSAC Postdoctoral Researcher October 5, 2010 | 12:30 to 01:30 | 540 Cory Hall, DOP Center Conference Room Host: Richard White

Modernization of the US power grid will necessitate the deployment of a large number of sensors for ubiquitous monitoring of the "smarter" grid. Mandated introduction of inherently variable renewable energy sources, such as wind and solar, as well as ongoing efforts in energy conservation, will require highly granular monitoring of the flow...

BSAC Seminar: Silicon Migration as a Process for Micro/Nano- Fabrication

October 19, 2010
Dr. Rishi Kant Postdoctoral Researcher, Department of Bioengineering and Therapeutic Sciences, UCSF BSAC MS 2005 October 19, 2010 | 12:30 to 01:30 | 540 Cory Hall, DOP Center Conference Room Host: John Huggins

Over the last decade, designers have sought to supplement traditional micro-fabrication with the ability to create 3D curved surfaces, in order to build new and novel micro-devices. One such technique is silicon migration (also known as hydrogen annealing in the MEMS community), which can transform traditional two-dimensionally extruded geometries...

BSAC Seminar: New Nanomaterials for High-Performance Energy Conversion and Storage

October 26, 2010
Prof. Dunwei Wang Department of Chemistry, Boston College October 26, 2010 | 12:30 to 01:30 | 540 Cory Hall, DOP Center Conference Room Host: Ali Javey

Limited by the availability of materials with suitable properties, research progress in energy conversion and storage has been extremely slow, creating a significant challenge in modern technological developments. The solution to this problem may be found in nanostructures, because the characteristic sizes of them fall in the same range as that of electronic behaviors relevant to energy-related processes...
