Dr. Camille Crittenden introduced the work by her organization CITRIS (http://citris-uc.org/) which is a collaboration between four UC campus in the SF Bay area: Berkeley, Davis, Merced and Santa Cruz, on humanitarian technology innovations and applications, in four core initiatives:

  • Data and Democracy
  • Health care
  • i4Energy
  • Intelligent Infrastructures


Under those initiatives, Tech applications have been developed to solve problems in  various areas, e.g.,

  1. Human Rights
    • Crisis mapping, remote sensing, video, forensic analysis, DNA, demographic data collection & analysis
  2. Governance & Democracy
  3. Economic development
    • Microfinance through crowd-sourced loans (http://www.Kiva.org)
    • SMS – popular tool to support agricultural decision-making
  4. Healthcare
    • mHealth: mobile applications for remote diagnostics  and care, use of SMS for medical advice
  5. Infrastructure
  6. Monitoring & evaluation
    • Surveys, remote data collection for feedbacks

Innovative Technologies for participatory assessment, e.g.:

Current challenges include:

  • Poor literacy rates
  • Regional conflicts
  • Climate changes
  • Health emergencies – Ebola, H1N1 etc.
  • Uneven access to the Internet and ICTs across the World

Growing number of communities involving in ICT:

  • Research funded by government and private investors
  • New programs by:
    • USAID
    • UCB Blum center
    • Development Impact Lab
    • Development engineering
  • GHTC and similar conferences

Image40M pixel camera in a mobile phone can be used to image the cells

~ 6-7 billion cell phones used worldwide

– use the HW & SW of cell phone as a new platform for telemedicine

Cell phone imaging technique 1: Light weight, compact & portable lens free super-resolution microscope

– need to place the specimen very close to the CMOS sensor, bypassing the lens on the mobile device and using separate LED light sources; prototype of fixtures on the mobile device created using 3-D printer

– Used as:

  1.  Albumin tester
  2. E. Coli sensor
  3. blood analyzer
  4. circulating tumor cell detection
  5. diagnostic test reader — complementary to OV 16 as presented by the previous speaker
  • test results can be distributed via wireless connectivity on the mobile device
  •  track diseases as a function of space & time through the valuable data collected

– CMOS imager, no lens, with computational functions on the chip

  • resolution: a few nm can be detected, e.g., viruses

– CMOS & CCD images

  • based on the Imaging of shadows
  • detect shadows of specimen
  • use to count cells (shadows)
  • similar to digital holograms
  • time-reverse re-construction iteratively

– CCD: telescope works on the same principle

– LEDs: partially coherent lights – better than laser; sunlight has been used recently

– For further details on the physics, consult publications @ http://innovate.ee.ucla.edu/

– Algorithm:

  1. iterative phase recovery as the first step
  2. FFT based
  3. time reverse the field

– push resolution to deeper sub micron

– digital holograms

– similar imaging results when compared with actual microscope

– Use case: monitor HIV patients

  • conventional equipment for CD4 count is very expensive and bulky
  • use microfludic device, e.g., LUCAS
  • based on shadows or counts
  • ratio of cells to be found
  • CD4 to CD8 ratio determines when to start the next stage of therapy
  • nano particles used to label different cellsm, e.g., gold labeled CD4 (Ag-CD4)
  • use a simple hologram

– lens free imaging with large field of view (FOV)

  • CMOS sensor: 240mm FOV this year, to be increased next year
  • increase aperture => resolution ~30mm
  • only one LED is on at any time
  • different LEDs are turned on each time
  • multi-frame super-resolution
  • different shift and synthesis using multiple frames to improve resolution
  • cell phone with high-end CMOS sensor chip FOV > 20 sq. mm, further improvement to 30 sq. mm possible

#Further information on lens free color imager to be presented ~12pm on Tuesday, during the students’ poster seesion

# Key characteristics of the cell phone CMOS camera: good resolution ~ 1mm with large FOV

  • decouple resolution from FOV with this type of imager (CMOS sensor)
  • In contrast, the conventional microscope is limited by a tradeoff between FOV and resolution

Cell phone imaging technique 2: Fluorescent imaging — very important

– No need to modify the mobile device, only need to add the external fixture

– detection of bacteria and parasites in water samples

– use blue LED and a very inexpensive filter

– labeled white blood cells counted

– captured and process samples

# Pixel counts of CMOS imaging sensor follow Moore’s law

– single virus can be detected without the need for a lot of light

– light projected at an angle instead of perpendicular to the sample to avoid direct reflections

– use of inexpensive filters

Q&A responses:

– Currently, calculations are performed on another computer offline

– possible to have computations performed on the iPad / tablet

– cost reduction: possible because of CMOS sensor – volume will drive the costs

– not tested for humidity & temperature, expected to work the same way

– Depth of field: great advantage of these techniques; modulating the shadow when the object is moved

Krista Bauer, GE Foundation
Technology Application in the Developing World: Think Local

“In Country, For Country” It is all about providing products that are relevant to the local people using them. When a public company has the expertise and will to do more, it has a way and GE is doing it. There are lots to learn along the way. Watch Krista’s presentation live now: https://ieeetv.ieee.org/event-showcase/ghtc2012 Be inspired!

Panelists from Left to Right, sharing valuable experience in developing, deploying and managing healthcare technologies in the developing world:
– Robert Nathan
– Rabih Torbay
– Robert
– Jim Imrie

“They know what they need. They know their priorities.” Rabih reminds us we may have the expertise to help but it’s the local people who truly know what they need and what is important to them.

“Establish a dialogue, establish the relationships” Erna talks from experience how we can start putting a feasible project together.

“If you can get to the business model point, that will drive sustainability” Jim made a point talking about helping a facility generate income with the collection and processing of rainwater off the roof for use and sale. “Differentiate the complexity as we see it from the complexity as they see it”
