IMG Seminar

This week, the speakers for the IMG Seminar are:

• Mark Yanchisin (EH&S) on Non-traditional safety
• Kangfu Chen (Dr. Fan's group) on A filter array regulated microflow (FARM) chip for circulating tumor cell isolation

A filter array regulated microflow (FARM) chip for circulating tumor cell isolation . Circulating tumor cells (CTC) are cancer cells in the circulating system shredded from the primary tumor. CTCs have been considered as important biomarkers for early detection of metastasis, therapy monitoring and disease prognosis. However, the rarity of CTCs in the blood (tens of CTCs per mL blood) remains a technological barricade. We developed a Filter Array Regulated Microflow (FARM) chip combing filtration and immunoaffinity based CTC capture. The FARM chip is able to isolate CTCs with low deformability or high antibody expression level. Even more deformable CTCs with lower antibody expression are likely to be captured if the two components combination exceeds the CTC capture threshold. Overall, this method is capable of isolating, detecting and enumerating CTCs with high throughput and superb efficiency.

With the Fall semester arriving, we will be having our IMG Kickoff Meeting on August 21, 2018 (day before classes start) from 11:45AM to 1:30PM. During this meeting, we'll discuss important IMG updates, introduce new members, recognize our accomplishments over the last year, and present some IMG awards. We may also try to take a group photo, so if you have a IMG polo or t-shirt, please wear it.

Please note, all IMG members are expected to attend this meeting. Pizza and drinks will be provided.

This week, the speakers for the IMG Seminar are:

• Camilo Vélez (Dr. Arnold's group) on Integrating microfabricated magnetic materials in 5G telecommunication systems
• Cary Kuliasha (Dr. Judy's group)

Integrating microfabricated magnetic materials in 5G telecommunication systems.  The microfabrication of ferrite structures on semiconductor substrates for mm-wave applications is an imminent necessity to the development of components in the 5^th generation of telecommunication systems (5G). A team from IMG is conducting research in this area under the DARPA/MTO program called: Magnetic Miniaturized and Monolithically Integrated Components (M³IC). We have implemented fabrication and characterization techniques that required our group’s combined know-how on MEMS, microfabrication, magnetics, nanoparticles, transmission lines and RF. During this seminar we will present techniques to pattern >100 µm thick barium hexaferrite (BaFe₁₂O₁₉) films on semiconductor substrates, revealing material’s peak signal absorption associated with ferromagnetic resonances at 45.9 GHz.

This week, the speaker for the IMG Seminar is Dr. Yong-Kyu Yoon on "Put the IoT where the Mouth is" - Smart Mouthguard and its Prospects.

Wearable IoT devices are getting elevated attentions in this connected world. A smart mouthguard - one of the first IoT wearables in the oral space, is presented as a future smart health platform. The evolution and specifications of some smart mouthguards developed in the lab are showcased. Its prospects and future directions are discussed with audience. Also, some impressions Dr. Yoon got from Consumer Electronic Show (CES) 2018 will be shared. 

This week, the speakers for the IMG Seminar are:

•  Haocheng Zhou (Dr. Sheplak's group) on MEMS-Based Five-Hole Probe with Optical Pressure Transducers
•  Dingkang Wang (Dr. Xie's group) on  Integrated Forward-View 2-Axis MEMS Scanner for Compact 3D Lidar

MEMS-Based Five-Hole Probe with Optical Pressure Transducers. This project focuses on a MEMS-based 5HP capable of measuring the localized velocity vector and the static&dynamic pressure in a flow field. By packaging multiple fiber-optic lever MEMS pressure sensors at the probe tip, this new device greatly reduces the settling time and offers higher bandwidth compared to traditional pneumatic 5HP. This talk is mainly about the fabrication process of five pressure transducers on a single die, the probe's hemispheric tip with ~100 µm (OD) holes on the tip surface, and the multi-fiber ferrule for optical packaging. 

Integrated Forward-View 2-Axis MEMS Scanner for Compact 3D Lidar. This project target at the integrated MEMS Scanner for MAV(Micro-air vehicles). The two vertically oriented mirror make forward view scan easy without difficult optical alignment. The weight of this MEMS scanner is only 20 mg, make it possible to be carried by MAV.

This week's invited speaker for the seminar is Dr. Alex Phipps, an IMG alumnus from Dr. Nishida's group. He will be presenting on "S&T in a Navy lab: A non-attributional rant on power electronics, microelectronic research, and how to work with the government."

This week, the speakers for the IMG Seminar are:

•  Yuzheng Wang (Dr. Arnold's group) on Electrodeposition of Thick CoPt Magnetic Films
•  Xiao Jiang (Dr. Fan's group) on Zika Virus Detection with 3D printed/paper-based Device

This week, the speakers for the IMG Seminar are:

11:55-12:20 pm: Dr. Alexandra Garraud on "Extending the range of wireless power transmission for bio-implants and wearables" 

12:20-12:45 pm: Todd Schumann  on "Solely calcine controlled ferroelectric/memristor behavior in barium titanate"

The speakers of this week's IMG seminar are

• Dr. Roozbeh Tabrizian on Linear or Nonlinear Nano-Acoustic Signal Processors for 5G Wireless Communication - One problem, two approaches,
• Mehrdad Ramezani, from Dr. Tabrizian's group, on High-Q Silicon Fin Bulk Acoustic Resonators for Signal Processing Beyond the UHF.

Professor Igor Bargatin from the University of Pennsylvania (UPenn), will be giving an interesting talk on development of novel meta-materials for Nano-Systems applications.  

Recently, they have demonstrated a new class of ultra-lightweight plate-shaped mechanical metamaterials. Using a periodic three-dimensional corrugation, they have fabricated free-standing plates up to a few cm in size out of aluminum oxide (alumina) films as thin as 25 nm. Weighing as little as 0.1 gram per square meter, they are among the thinnest and lightest free-standing solids that can be handled with bare hands. Like the nanotruss mechanical metamaterials reported by other groups, plate mechanical metamaterials are extremely lightweight and resilient due to their nanoscale thickness and microscale cellular structure. Ultralow weight, mechanical robustness, thermal insulation, as well as chemical and thermal stability of alumina make plate metamaterials attractive for numerous applications, including microflyers, high-temperature heat-to-electricity energy converters, as well as and hollow MEMS/NEMS resonators.
