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...

BSAC Seminar: Standards-Based Protocol Stacks for Low-Power Wireless Communication

November 2, 2010
Dr. Thomas Watteyne Department of Electrical Engineering and Computer Sciences, UC Berkeley BSAC Postdoctoral Researcher November 2, 2010 | 12:30 to 01:30 | 540 Cory Hall, DOP Center Conference Room Host: Kris Pister

The Internet of Things revolution is quietly coming, and with it an epochal turnpoint in wireless network design. Major standardization bodies have been looking at how wireless multi-hop networks should operate reliably (IEEE 802.15.4E, IETF RPL), how they can integrate within the Internet (IETF 6LoWPAN), and how utilities and end users...

BSAC Seminar: Silicon MEMS Oscillators - From Research to Products

November 16, 2010
Dr. Wan-Thai Hsu CTO, Discera November 16, 2010 | 12:30 to 01:30 | 540 Cory Hall, DOP Center Conference Room Host: Clark Nguyen

This seminar first reviews the development history of MEMS resonators and oscillators. The evolution of MEMS resonator designs as well as transducer designs will be discussed, and the interface circuitry that is necessary to deal with special characteristics of MEMS resonators will be presented. Often taken for granted in research environments, MEMS fabrication processes and wafer level packaging...

BSAC Seminar: Heat Transfer and Fluid Dynamics in Micro-Scale Truss Structures

November 9, 2010
Dr. Chris Roper HRL Laboratories BSAC PhD 2007 November 9, 2010 | 12:30 to 01:30 | 540 Cory Hall, DOP Center Conference Room Host: Roya Maboudian

Microfabricated heat sinks and heat exchangers are of increasing interest for numerous applications, including electronics cooling, due to the enhancement of convective heat transfer as well as an increase in surface area per unit volume with reduction in characteristic length scale. High cost per unit volume and limitations on device thickness severely constrain the applicability of heat transfer devices...

BSAC Seminar: Microengineered Hydrogels for Stem Cell Bioengineering and Tissue Regeneration

November 23, 2010
Prof. Ali Khademhosseini College of Biomedical Engineering, Harvard Medical School November 23, 2010 | 12:30 to 01:30 | 540 Cory Hall, DOP Center Conference Room Host: Luke Lee

Micro- and nanoscale technologies are emerging as powerful tools for controlling the interaction between cells and their surroundings for biological studies, tissue engineering, and cell-based screening. In addition, hydrogel biomaterials have been increasingly used in various tissue engineering applications since they provide cells with a hydrated 3D microenvironment that mimics...

BSAC Seminar: Connectivity Brokerage - Enabling Seamless Cooperation in Wireless Networks

November 30, 2010
Arash Parsa Graduate Student Researcher, Berkeley Wireless Research Center November 30, 2010 | 12:30 to 01:30 | 540 Cory Hall, DOP Center Conference Room Host: John Huggins

The explosive growth in the density of wirelessly-connected devices and their traffic load is increasing the interference level and gradually leading to severe spectrum shortage. Traditional approaches to address this challenge, such as spectrum regulation, improvement in spectral efficiency and reducing cell sizes, are running out of steam or are facing operational roadblocks....
