The sensor revolution

16.02.2004


NSF sensors activities in focus at AAAS annual meeting in Seattle



In the 1990s, the Internet connected us to a planet-wide web of information-all the zillions of bits that are stored in computer memories and hard drives. But now, thanks to an ongoing revolution in highly miniaturized, wirelessly networked sensors, the Internet is reaching out into the physical world, as well.

"We call it ’the Embedding of the Internet’," says Deborah Estrin, who is a computer scientist of the University of California, Los Angeles, and director of the Center for Embedded Networked Sensing, a multi-university research partnership that was launched in August 2002 with funding by the National Science Foundation (NSF). "And it’s going to transform our ability to understand and manage the physical world around us."


Indeed, that prospect has led the NSF to fund sensor research for the past decade and more, culminating in a foundation-wide Sensors and Sensor Networks Program that was begun in 2003 with a first-year funding of $47 million. Among the likely applications:


Networks of wireless environmental sensors could be deployed in remote areas to monitor factors such as the moisture load of the vegetation (and thus the degree of fire danger); agricultural runoff in rivers, streams, and groundwater; seismic events; air quality; and the ecosystem’s overall response to climate change.

Bridges and buildings with built-in sensor networkscould report on their own structural integrity, and pinpoint internal damage after an earthquake.

Networks of miniature chemical and biological sensors could be deployed in hospitals, post offices, and other sensitive areas to raise the alarm at the first sign of anthrax, smallpox, ricin, or other indications of a terrorist attack.

Clusters of "smart," but almost undetectably small sensors could be scattered across a stretch of hostile territory by air to monitor traffic and troop movements.
Sensors and their applications will also be very much in evidence at the Seattle meeting of the American Association for the Advancement of Science (AAAS). Among the most prominent events will be two topical lectures:

Deborah Estrin: Instrumenting the World with Wireless Sensor Networks Friday, February 13, 2004, 1:30 to 2:15 p.m.

Larry R. Dalton: Electro-Optics for the Next Generation Information Technology, Sensing, And Defense Applications Friday, February 13, 2004, 1:30 to 2:15 p.m. Dalton is director of the NSF-funded Center on Materials and Devices for Information Technology Research at the University of Washington.

But other sessions will be dealing with sensors, as well:

Cyberinfrastructure: Revolutionizing Environmental Science in the 21st Century Friday, February 13, 2004, 9:00 a.m. - 12:00 noon & 2:30 p.m. -5:30 p.m. Estrin will be giving a technical talk in the afternoon session. "Cyberinfrastructure" is a term that ’s come to describe NSF’s most expansive, long-term vision of computing-a vision that most definitely includes extensive sensor networks.

Miniaturization of Chemical, Energy and Biological Systems for Security Applications Friday, February 13, 2004, 2:30 p.m. - 5:30 p.m.

2004 Nanotechnology Seminar: Chemical and Biological Nanosensors Friday, February 13, 2004, 10:00 a.m. - 1:00 p.m.

21st Century Photonics Sunday, February 15, 2004, 9:00 a.m. - 12:00 noon & 2:30 p.m. -5:30 p.m. Larry Dalton will be speaking in the morning session.

Im Focus: Making Waves

Computer scientists use wave packet theory to develop realistic, detailed water wave simulations in real time. Their results will be presented at this year’s SIGGRAPH conference.

Think about the last time you were at a lake, river, or the ocean. Remember the ripples of the water, the waves crashing against the rocks, the wake following...

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
