citris mission
CITRIS was created by the previous Governor’s initiative in ~2000 to bring new focus on societal scale challenges

Four UC campuses are focused on applying IT to..

Intelligent Infrastructure

Energy, water, earthquake preparedness, security…

Health care and bio-medical services/products

Services Science (especially encouraged by IBM)

The center is funded by the State of California and industry

A new building is presently under construction on our main campus …

It will host major laboratories (including space for BWRC as needed) + a state of the art NanoFabrication Laboratory

what s the difference between bwrc and citris
CITRIS works with its affiliate centers – BWRC as a leading example --- towards commercial & social impact

For BWRC supporters CITRIS provides an additional impact opportunity --- to “funnel” our basic core science (WSNs, UWB, 60GHz etc) into commerce, societal problems, and shifts in public policy

No other CA organization brings the multi-disciplinary horsepower together, to focus on innovative technology “in the service of society,” like CITRIS

CITRIS provides a unique “glue” and “roll-out opportunity” for seemingly disparate activities

What’s the difference between BWRC and CITRIS?
bwrc as a feeder to citris
Put in another way….

How is CITRIS different from BWRC… but how do the two operations work together?

BWRC is in the “research business” of fundamental research in low power radios, UWB, >60GHz..

CITRIS is in the “research business” of applying these fundamental ideas to new products, new health services, energy efficiency, homeland security …

BWRC as a “feeder” to CITRIS
bwrc as a feeder to citris1
A BWRC thesis: “Ultra Low Power Transmitters for Wireless Sensor Networks,” The thesis proposed the design and optimization of nodes for wireless sensor networks with ultra low power, namely: consume less than 100 microwatts of average power for a long life; cost less than $1 for a low system cost; and occupy less than one cubic centimeter (Yuen Hui Chee)

A CITRIS thesis: Wireless sensor networks for energy efficiency. This thesis reports on packet-level performance of 2.4GHz Telos wireless sensor nodes in residential environments. The objective is to characterize the packet loss to determine the necessity of mesh networking for residential wireless sensor networks. The results describe two deployments in four residential houses (Nate Ota)

BWRC as a “feeder” to CITRIS
how we think about citris projects
If successful, how will it change the world? = Societal pull

How will it use CITRIS technology/skills = “Tech. push”

Does it leverage multi-campus CITRIS research teams?

Are the metrics for success well-established?

Has it passed competitive peer review: awarded federal or State funding?

Can our corporate/federal/state sponsors find enough value to buy in?

Are student initiatives (e.g., student clubs) represented?

Sponsor international symposium in this area?

Constantly strive for synergy among 4 (not 1) campuses and sponsors

How we think about CITRIS projects…
citris project overview
1. Intelligent infrastructures



Natural disasters


TIER – (projects for the developing world)

2. Healthcare

Implantable wireless sensors (BSN)

Link to home-wireless

IT services

3. Services: Science, Management, and Engineering

Academic curriculum

Research agenda



CITRIS project overview




1 bwrc citris intelligent infrastructures
For intelligent infrastructures, BWRC/CITRIS provides the leverage for:

Generic technology – hardware platforms (motes) shared by all…

Common elements – low-power radios, sensors, MEMS-sensors,

Common software – TinyDB, Deluge,

Common labs

Testbeds at Berkeley (Soda, Etcheverry, Cory, BWRC) Merced, Santa Cruz, Davis

Common infrastructure is raising all boats

Annual symposium on intelligent infrastructures planned

  • Cyber-infrastructure
  • Natural Disasters
  • Transportation
  • Energy
  • Water
  • Health Care
1. BWRC + CITRIS = Intelligent infrastructures
1 bwrc citris intelligent infrastructures also relates to california governor s proposal
1950s and 1960s phenomenal investment in the state’s highways, ports, energy & water supply systems, schools and universities created the 6th largest economy in the world

In 1955 the population was ~13 million but by 2025 it will be 46 million

Older investments showing their age + expansion needs added resources

Strategic growth plan ~$250b. – first 10/20 year effort

Calls for “expanded authority to fund and deliver projects through a variety of public-private partnerships”

1. BWRC + CITRIS = Intelligent infrastructures (also relates to California Governor’s proposal)
2 bwrc citris health care dollar opportunities
2. BWRC + CITRIS = Health Care dollar opportunities
  • We spend $ 2 T per year in health care (16% of GDP).
  • 10 % of population over 60 expected to grow to 25 % by 2030.
  • Huge opportunities to make a difference in continuous monitoring (tele-medicine) for chronic conditions, elder care.
2 bwrc citris health care dollar opportunities1
Implantables and wireless monitoring (see Jan’s talk)

Exquisite Detection: presymptomatic detection of disease (BSAC leading the way with lab on a chip, bio-sensors,..)

Use of EDA like methods to do open source analysis of gene-protein, protein-protein networks: Biospice, SynBio (joint with QB-3)

Stem Cell Initiative and Tissue Engineering (including social, legal and ethical considerations)

2. BWRC + CITRIS = Health Care dollar opportunities
3 bwrc citris impact at service layer using health care here as an example
What impact can mobile phones have on user health?

Imperial College, Rifat Atun et al., Vodaphone (3.25.06)

150 examples of text messaging in health care delivery

1) Efficiency gains: reduce number of lost appointments (UK)

26-39% (GPs), 33-50% (Hospitals) = £256-364m. Savings

2) Public-health gains: hard to reach locations / also teenagers!

WHO: India > Tuberculosis: Kenya, Nigeria, Mali > HIV&Malaria

3) Treatment regime: take medicine now! exercise! don’t smoke!

Diabetes is a good example of this requiring constant management

“Good” patients measure blood-sugar levels and inject insulin 3x/d

V. Franklin (Dundee), “Sweet Talk” > Text messages to teenagers

Increased “self-efficacy,” haemoglobin HbA1c was 14% lower

3. BWRC + CITRIS = Impact at “Service Layer” (using Health Care here as an example)
summary bwrc citris adoption needs lower power radios cheaper devices 100 m w integrated node


+ Antenna






























Summary: BWRC >> CITRISAdoption needs lower power radios & cheaper devices <100 mW integrated node
  • Simplest possible processor
  • Dedicated accelerators when needed
  • Aggressive power management
  • Minimizing supply voltage
