BSAC Seminar: Implantable Intraocular Sensor with Remote Readout for Glaucoma Management

May 10, 2016
Prof. Hyuck Choo Department of Electrical Engineering, California Institutue of Technology BSAC Postdoc 2008 May 10, 2016 | 12:00 to 01:00 | 490 Cory Hall Host: Richard Muller

Glaucoma is a leading cause of irreversible blindness with 60 million cases worldwide. An elevated intraocular pressure (IOP) level has been identified as a major risk factor and all glaucoma therapies are focused on lowering the IOP level. Moreover, recent large-scale studies sponsored by the National Institutes of Health have found that patient's IOPs fluctuate...

BSAC Seminar: Novel MEMS Mask Layout Tool: Layout, a Free Academic MEMS Mask CAD Software Package

October 17, 2016
Roger Doering California State University, East Bay October 17, 2016 | 12:00 to 01:00 | 521 Cory Hall Host: M. Wasilik

Inspired by work done at BSAC using the XKIC package, and under development for four years, Layout is a 2.5 D graphics program running on the Windows platform that uses OpenGL to take advantage of modern graphic cards processing power. Full support of the GCA pattern generator in use at Berkeley, is inherent in the tools that provide circles, arcs, rotated boxes, wires and even generalized polygons. A "wire45" tool...

BSAC Seminar: Fluids and Photons: Optofluidics Comes of Age

October 11, 2016
Dr. Hans Zappe Department of Microsystems Engineering, University of Freiburg, Germany October 11, 2016 | 12:00 to 01:00 | 490 Cory Hall Host: Roya Maboudian

The use of liquids and interfaces for sculpting optical wavefronts has led to a broad spectrum of optical components, some clever, some useful, occasionally both. The combination of micro-fluidics, micro-optics and micro-fabrication has been employed to realize, for example: tunable lenses; optical switches; fluidic waveguides; liquid lasers; reconfigurable apertures. A key feature of...

BSAC Seminar: Digital Holography Microscopy: How 4D Optical Profilometry Brings New Insights for Your Research, Development, and Quality Controls

September 13, 2016
Dr. Yves Emery CEO, Lyncée Tec SA September 13, 2016 | 12:00 to 01:00 | 490 Cory Hall Host: David Horsley

Digital Holographic Microscopes (DHM®) are 3D optical profilometers with unique temporal capacities. Contrary to usual measurement techniques, DHM® does not require any scanning mechanism to acquire information. Time sequences of 3D data are therefore acquired at camera rate providing 4D topography measurements.

Spatial resolution is interferometric where: vertically resolution is below the nanometer for any choice of objective, and...

BSAC Seminar: Microelectronics: The Missing Cancer Drug - Creating Tomorrow’s Cures with New Sensors Unlocking Today’s Therapies

November 1, 2016
Dr. Mekhail Anwar Department of Radiation Oncology, UCSF BSAC Postdoc 2014 November 1, 2016 | 12:00 to 01:00 | 490 Cory Hall Host: Bernhard Boser

While the statistics surrounding cancer are simultaneously humbling and inspiring, they hide a key need in cancer care: the fundamental limiting reagent in cancer therapy is not the lack of treatment modalities, but the chasm between the spatial and...

BSAC Seminar: Printed Electrochemical and MEMS Sensors for Air Quality and e-Health Applications

November 15, 2016
Dr. Joe Stetter President & CTO, KWJ Engineering November 15, 2016 | 12:00 to 01:00 | 490 Cory Hall Host: Michael Cable

KWJ and partner SPEC-Sensors LLC have fabricated a family of miniature, yet high-performance, Screen Printed Electro-Chemical [SPEC] gas sensors for air quality (indoor and outdoor) and wearable personal exposure monitoring. We have advanced gas sensor technology to the point where we are able to bridge the cost-performance-gap. New devices in distributed high volume environmental and wearable markets using SPEC sensors are appearing. Sensing in...

BSAC Seminar: Magnetic Shape Memory: From Terminator 2 to Microfluidics

November 29, 2016
Dr. Peter Müllner Micron School of Materials Science and Engineering, Boise State University November 29, 2016 | 12:00 to 01:00 | 490 Cory Hall Host: Michael Cable

You may have seen something like magnetic shape memory (MSM) alloys at the movies. In Terminator 2, a “liquid metal” robot faces-off against a more traditionally engineered robot. Although not humanoid, MSM alloy uses the same basic principle: it shape-shifts. Apply a magnetic field, and the material responds with a shape change. Remove the field, and the new shape...

BSAC Seminar: Integrated Nanoscale Antenna-LED for On-Chip Optical Communication

May 2, 2017
Seth Fortuna Department of Electrical Engineering and Computer Sciences, UC Berkeley BSAC Graduate Researcher Dissertation Presentation May 2, 2017 | 12:00 to 01:00 | 540 Cory Hall Host: Ming Wu

Traditional semiconductor light emitting diodes (LEDs) have low modulation speed because of long spontaneous emission lifetime. Spontaneous emission in semiconductors (and indeed most light emitters) is an inherently slow process owing to the size mismatch between the length of the atomic optical dipole oscillations responsible...

BSAC Seminar: Single Crystal Diamond as a Material for Micro- and Nanosystems

January 23, 2018
Prof. Niels Quack Ecole Polytechnique Federale de Lausanne (EPFL) BSAC Postdoc, 2014 January 23, 2018 | 12:00 to 01:00 | 540 Cory Hall Host: Ming Wu

The extraordinary material properties of single crystal diamond provide great promise for numerous micro- and nanosystems: the wide spectral range of transparency from the UV into the far IR, in combination with high thermal conductivity, mechanical hardness, chemical resistance and biocompatibility make the case for outstanding photonic components, while the combination of high elasticity and crystalline structure...

BSAC Researcher Seminar: FMCW Lidar: Scaling to the Chip-Level and Improving Phase-Noise-Limited Performance

November 28, 2017
Phillip Sandborn Philip Sandborn Department of Electrical Engineering and Computer Sciences, UC Berkeley BSAC Graduate Researcher November 28, 2017 | 12:00 to 01:00 | Wozniak Lounge, 430 Soda Hall Host: Ming Wu

Lidar (light detection and ranging) technology has the potential to revolutionize the way automated systems interact with their environments and their users. Most lidar systems in industrial use rely on pulsed (or "time...
