BSAC Seminar: Surface Microfluidics: From Bio-Inspired Superhydrophobicity to Novel Fluidic Operations

March 29, 2011
Prof. Tingrui Pan Department of Biomedical Engineering, UC Davis March 29, 2011 | 12:00 to 01:00 | 540 Cory Hall, DOP Center Conference Room Host: David Horsley

Superhydrophobicity, also known as Lotus effect, has attracted numerous academic and industrial interests since its original discovery in the late 1980s. The remarkable water repellency and interfacial metastability on the natural superhydrophobic surfaces lead to discovery of intriguing physicochemical phenomena and principles at the micro-nanoscopic interface. For its further...

BSAC Seminar: Flexible 4,096-Pixel Multi-Electrode Arrays of Electrodes, CMOS and Image Sensors: A Device for Interfacing Neural Circuitry and a Basis for Retinal Prosthesis

April 5, 2011
Prof. Long-Sheng Fan National Tsing Hua University/UC Berkeley April 5, 2011 | 12:00 to 01:00 | 540 Cory Hall, DOP Center Conference Room Host: John Huggins

To achieve localized retinal neural stimulation with high granularity over reasonable field of view within power constraints, we integrated a flexible 4,096-element retina chip 30 um in total thickness including passivation layers using a flexible 180nm CMOS Image Sensor (CIS) technology. The retina chip is 3x3 mm in size (including multiplexing electronics for pixel characterizations) with an...

BSAC Seminar: High-Q and Low-Impedance MEMS Resonators for Communication Applications

April 6, 2011
Li-Wen Hung Department of Electrical Engineering and Computer Sciences, UC Berkeley BSAC Researcher, Disseration Presentation April 6, 2011 | 02:00 to 03:00 | 400 Cory Hall, Hughes Room Host: Clark Nguyen

With an increased need for regional and global roaming and continuous advances in wireless communication standards, future transceivers need to support multi-mode operation without increasing in cost, hardware complexity, and power consumption. Channel-selection filters offer a solution for more simplified and versatile transceivers....

BSAC Seminar: Ultra-High Density, Probe-Based Nonvolatile Memory Technology using Ferroelectric Recording Media: Issues and Solutions

April 12, 2011
Noureddine Tayebi Graduate Researcher, Stanford University/Intel April 12, 2011 | 12:00 to 01:00 | 540 Cory Hall, DOP Center Conference Room Host: John Huggins

Probe-based nonvolatile memory using ferroelectric media is an ideal candidate for future ultra-high density (> 1 Tbit/inch^2) memory devices. In such a device, an array of atomic force microscope (AFM) probes is used to write data by applying short electrical pulses to invert the polarization of local film volumes. However, no commercial product has reached the...

BSAC Seminar: Toward Closing the Loop: Circuits and Systems for Real-Time Neurochemical Sensing and Activity-Dependent Intracortical Microstimulation

April 26, 2011
Prof. Pedram Mohseni Department of Electrical Engineering and Computer Sciences, Case Western Reserve University April 26, 2011 | 12:00 to 01:00 | 540 Cory Hall, DOP Center Conference Room Host: Michel Maharbiz

To date, brain-machine interfaces (BMIs) have sought to interface the brain with the external world using intrinsic neuronal signals as input commands for controlling external devices, or device-generated electrical signals to mimic sensory inputs to the nervous system. A new generation of neuroprostheses is now emerging that aims to combine...

BSAC Seminar: Functional Contact Lenses

May 3, 2011
Prof. Babak Parviz University of Washington May 3, 2011 | 12:00 to 01:00 | 540 Cory Hall, DOP Center Conference Room Host: John Huggins

Integration of miniature functional devices on contact lenses provides a unique opportunity for collecting information from and providing information to a user. This talk provides a brief overview of recent efforts at the University of Washington to design, build, and test a contact lens that may incorporate small optical elements or sensors. The UW group has demonstrated the integration of antennas, small radios, and...
