(CITRIS Director Shankar Sastry and Executive Director Gary Baldwin)
Four UC campuses are focused on applying IT to..
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 LaboratoryCITRIS mission
Our prototype system balances occupant comfort vs. price preferences with automatic, reactive short-term load shedding and long-term energy reduction

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 activitiesWhat’s the difference between BWRC and CITRIS?
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
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 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 sponsorsHow we think about CITRIS projects…
TIER – (projects for the developing world)
Implantable wireless sensors (BSN)

3. Services: Science, Management, and Engineering
ServicesCITRIS project overview
Generic technology – hardware platforms (motes) shared by all…
Common elements – low-power radios, sensors, MEMS-sensors,
Common software – TinyDB, Deluge,
Testbeds at Berkeley (Soda, Etcheverry, Cory, BWRC) Merced, Santa Cruz, Davis
Common infrastructure is raising all boats
Annual symposium on intelligent infrastructures planned
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)
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
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% lower3. BWRC + CITRIS = Impact at “Service Layer” (using Health Care here as an example)
DLLSummary: BWRC >> CITRISAdoption needs lower power radios & cheaper devices <100 mW integrated node
