Where Next? http://www.wsnblog.com/2012/02/09/energy-harvesting-for-wireless-sensors-1-6-million-units-in-2011-where-next/ http://www.wsnblog.com/2012/02/09/energy-harvesting-for-wireless-sensors-1-6-million-units-in-2011-where-next/#comments Thu, 09 Feb 2012 09:10:12 +0000 Marco Zennaro http://www.wsnblog.com/?p=4110 In 2011 the market for energy harvesters reached US$700 million, with the majority of the value going into consumerelectronic applications, where energy harvesters have been used for some time. Approximately 1.6 million energy harvesters were used in wireless sensors, resulting in $13.75 million being spent on this market segment. The next few years will see a growth in the adoption of energy harvesting for wireless sensors with the market for industrial applications reaching US$140 million by 2017. Wireless sensor networks will be as big as US$200 million with bespoke military/aerospace applications reaching US$210 million (Market data taken from the IDTechEx report “Energy Harvesting and Storage for Electronic Devices 2011-2021″, www.IDTechEx.com/energy).

The volume of harvesters (in units) sold into each of the market segments will vary significantly, mainly because of the different size/power output/specifications for each harvester in each market segment. For example, military and aerospace applications will account for approximately 70,000 units of high value harvesters in 2017, whereas industrial applications will reach over 40 million units.

iDigi Device Cloud enables cloud connected devices over satellite networks with Iridium http://www.wsnblog.com/2012/02/08/idigi-device-cloud-enables-cloud-connected-devices-over-satellite-networks-with-iridium/ http://www.wsnblog.com/2012/02/08/idigi-device-cloud-enables-cloud-connected-devices-over-satellite-networks-with-iridium/#comments Wed, 08 Feb 2012 09:06:39 +0000 Marco Zennaro http://www.wsnblog.com/?p=4107 From Digi’s blog:

The Iridium satellite network now supports the iDigi Device Cloud. This means that Digi devices with an Iridium data transceiver inside can now send and receive data via iDigi over the Iridium network.

The Iridium network is the world’s furthest-reaching network, so this capability extends connectivity to the remote corners of the globe and is faster and easier than ever before.

“The big picture is that we’ve made it ridiculously easy to create backcountry realtime environmental stations, operate autonomous terrestrial or oceanic vehicles or support advanced devices in the developing world,” said Rob Faludi, collaborative strategy leader for Digi R&D. “Developers can create high-tech interactions that persist though natural disasters because no local infrastructure at all is required, and deploy them in any spot on the planet. We say any app, anything, anywhere and we mean anywhere!”

Iridium and Digi create a valuable partnership– with Iridium operating the world’s furthest-reaching network and enabling connections in remote places and Digi, who continually pushes the bounds of technology in terms of what is possible through networks.

This Is NASA’s Cancer-Sniffing Cellphone Sensor http://www.wsnblog.com/2012/02/02/this-is-nasas-cancer-sniffing-cellphone-sensor/ http://www.wsnblog.com/2012/02/02/this-is-nasas-cancer-sniffing-cellphone-sensor/#comments Thu, 02 Feb 2012 08:42:32 +0000 Marco Zennaro http://www.wsnblog.com/?p=4100 What if you could use your phone to test the air for toxins? What if you could monitor your health simply by blowing on it? Sounds amazing, right? Nanosensor technology developed by NASA Ames is going to make that a reality.

Jing Li, a scientist at NASA Ames, has been working for years on what will be the greatest phone accessory of all time. It’s a small chip (about the size of a postage stamp) that houses 32 nanosensor bars. Each bar is composed of a different nano-structure material. Because each sensor bar is unique it can respond to different chemicals in different ways, enabling it to not only differentiate between them, but also to monitor their relative levels, in real time.

In its current state (which is looking mighty close to production-ready), it’s housed in a small case that attaches to a smartphone. For legal reasons they wouldn’t say which smartphone it’s built to attach to, but you can probably guess. Eventually, it will be built to attach to many other popular models. The idea is to develop a low-cost version so that consumers can afford to have them for health and safety applications. But let’s back up a second.

This nanosensor technology was originally developed by NASA Ames for space applications. This is NASA, after all. The first usage was monitoring for fuel leaks around launch vehicles. They’ve been on the International Space Station since 2008, monitoring air-quality and checking for formaldehyde in the air. Future applications could include taking samples on asteroids and Mars missions. So that’s where it started, but the Department of Homeland Security is now funding this project in order to bring it back down to earth—and to consumers.

There are certainly military applications (the Department of Defense is funding an implementation where soldiers could wear these to alert them of chemical threats), but the cellphone implementation is aimed squarely at consumers. The chip only draws 5 milliwatts, which means very little battery-drain (the smartphone they tested it with can use the sensor for 8 continuous hours on a single charge). It’s primarily being developed to monitor carbon monoxide as well as chlorine, ammonia, and methane in your home.But these things could really be used anywhere because they’re so small. An app could automatically send data back to the Department of Homeland Security or other emergency services agencies, which would give them a big-picture look at a larger area—and let them know if a mass evacuation is needed.

Wireless Sensors Monitor Brain-Waves on the Fly http://www.wsnblog.com/2012/02/02/wireless-sensors-monitor-brain-waves-on-the-fly/ http://www.wsnblog.com/2012/02/02/wireless-sensors-monitor-brain-waves-on-the-fly/#comments Thu, 02 Feb 2012 08:39:42 +0000 Marco Zennaro http://www.wsnblog.com/?p=4097 A fighter pilot heads back to base after a long mission, feeling spent. A warning light flashes on the control panel. Has she noticed? If so, is she focused enough to fix the problem?

Thanks to current advances in electroencephalographic (EEG) brain-wave detection technology, military commanders may not have to guess the answers to these questions much longer. They could soon be monitoring her mental state via helmet sensors, looking for signs she is concentrating on her flying and reacting to the warning light.

This is possible because of two key advances made EEG technology wireless and mobile, says Scott Makeig, director of the University of California, San Diego’s Swartz Center for Computational Neuroscience(SCCN) in La Jolla, Calif. EEG used to require users to sit motionless, weighted down by heavy wires. Movement interfered with the signals, so that even an eyebrow twitch could garble the brain impulses.

Modern technology lightened the load and wirelessly linked the sensors and the computers that collect the data. In addition, Makeig and others developed better algorithms—in particular, independent component analysis. By reading signals from several electrodes, they can infer where, within the skull, a particular impulse originated. This is akin to listening to a single speaker’s voice in a crowded room. In so doing, they are also able to filter out movements—not just eyebrow twitches, but also the muscle flexing needed to walk, talk or fly a plane.

Can China crack the Internet of Things? http://www.wsnblog.com/2012/01/30/can-china-crack-the-internet-of-things/ http://www.wsnblog.com/2012/01/30/can-china-crack-the-internet-of-things/#comments Mon, 30 Jan 2012 14:12:21 +0000 Marco Zennaro http://www.wsnblog.com/?p=4087 It’s heralded as TNBT (the next big thing), high on any self respecting futurist’s to do list for 2012. Yet industry insidersremain sceptical that the Internet of Things (IoT) will reach fruition, this year, at least. They cite costs, technical prowess, planning and government support as some of the hurdles which need to be negotiated before we can get on the road to technological nirvana (or anti privacy hell, as some would have it) and our environment, buildings, vehicles, clothing and devices are all  sensing, communicating, networking and producing masses of beautiful data.

However, in China, costs, technical prowess, planning and government support would not appear to be a problem. The country’s Ministry of Industry and Information Technology implied last month, in its 12th Five-year Development Plan of the Internet of Things, that it will actually be bringing forwards development goals and roadmaps for IoT, together with further measures to support and promote the development of the industry.

This month Beijing invested in a laser writing scheme for pork products. The capital city consumes 30,000 pigs a day over the New Year period and it’s the national favourite meat. However, eating pork can be dangerous: 4 million pounds of it had to be recalled by the government last year after pigs from central provinces were found to have been injected with a fat-reducing drug. Even if the meat is safe, many Chinese complain of water being injected into the meat to increase its weight.

Printed Sensors Could Help Save You From Spoiled Food http://www.wsnblog.com/2012/01/25/printed-sensors-could-help-save-you-from-spoiled-food/ http://www.wsnblog.com/2012/01/25/printed-sensors-could-help-save-you-from-spoiled-food/#comments Wed, 25 Jan 2012 11:47:35 +0000 Marco Zennaro http://www.wsnblog.com/?p=4082 From Wired:

Whenever I pick up a package of frozen raw meat from the grocery store, I wonder, “Has this been frozen the whole time? How many times did it thaw and re-freeze?” It’s a disquieting thought, especially because there’s currently no easy way to tell.

But it looks like the ambiguity is about to end. In partnership with PST Sensor, Thinfilm, which produces printed re-writable memory, will begin making the first fully printed temperature sensor systems to monitor perishable items like food and pharmaceuticals.

“It’s a smart object that’s entirely self-contained,” Jennifer Ernst, Thinfilm’s North American VP told Wired.

That may sound familiar. It’s a key element of a concept called “The Internet of Things,” which basically refers to an imagined future where nearly every object will include embedded chips that can store data and interact with networks.

Thinfilm’s first-gen sensors will be able to cache data about the object itself, on the item itself. In this case, the sensors will record data concerning the object’s temperature history, tracking precise time, temperature and exposure information, and also displaying it in a low-power readout. The data within can be accessed as needed, insomuch it doesn’t need to be retrieved from the cloud, or require a constant wireless connection.

In the past, we’ve seen thin food sensors that change color as food begins to spoil. But this type of technology doesn’t retain data, and thus doesn’t provide information about the history of a product as it shipped.

NXP and Belkin Bring 6LoWPAN Connectivity to the Home http://www.wsnblog.com/2012/01/24/nxp-and-belkin-bring-6lowpan-connectivity-to-the-home/ http://www.wsnblog.com/2012/01/24/nxp-and-belkin-bring-6lowpan-connectivity-to-the-home/#comments Tue, 24 Jan 2012 11:39:25 +0000 Marco Zennaro http://www.wsnblog.com/?p=4080 What if every device in your home had its own Internet IP address? At the 2012 International CES, NXP Semiconductors  and Belkin International, Inc. will demonstrate a “smart home” network that allows you to control light bulbs — each with its own IPv6 address — using a smartphone or tablet. The network features a WeMo device from Belkin that enables mobile devices using Wi-Fi to interact securely with smart home appliances using JenNet-IP — NXP’s ultra-low-power wireless connectivity software based on 6LoWPAN and IEEE 802.15.4. The WeMo Home Automation demo will be featured in the NXP booth (CP8) and Belkin booth (South Hall #30651) at CES, and a preview is available here.

“We’ve released a series of tremendously popular smart lighting and smart home control videos on YouTube featuring JenNet-IP, and are often asked, ‘Where can I get the router?’” said Sean McGrath, general manager, smart home and energy product line, NXP Semiconductors. “At CES, you’ll see a number of solutions, including an easy-to-use WeMo device from Belkin you can attach to your home router, enabling it to serve as a secure gateway between your smartphone and the Internet-enabled appliances in your network using JenNet-IP. We’re very excited that Belkin, a world-class provider of connectivity solutions, is bringing JenNet-IP into its new WeMo Home Automation ecosystem.”

“Our WeMo Home Automation platform makes it easy for Belkin partners to develop appliances for the Intelligent Home. Wi-Fi is everywhere and will play an important role, but at the same time, we need low-power networking options to connect smart appliances and smart meters monitoring energy usage. Using only one-tenth of the power required by Wi-Fi, JenNet-IP offers robust, ultra-low-power connectivity which can support dozens or even hundreds of devices in a smart home network,” said Kevin Ashton, general manager of Belkin’s Conserve Business Unit.
