For the first time, a piezoelectric harvesting device fabricated by MEMS technology generates a record of 85μW electrical power from vibrations. A wafer level packaging method was developed for robustness. The packaged MEMS-based harvester is used to power a wireless sensor node. Within the Holst Centre program on Micropower Generation and Storage, imec researchers developed a temperature sensor that can wirelessly transmit data in a fully autonomous way. http://www.physorg.com/news180120643.html Technology Tue, 15 Dec 2009 17:40:05 EST news180120643 (PhysOrg.com) -- Salt and paper battery can be used in many low-power devices, such as medical implants, RFID tags, wireless sensors and smart cards. This battery uses a thin-film which makes it an attractive feature for many portable devices that draws a low current. http://www.physorg.com/news172241467.html Technology Tue, 15 Sep 2009 13:52:18 EST news172241467 (PhysOrg.com) -- Agricultural Research Service (ARS) scientists are developing a system that saves water by using aerial imagery and ground-based sensors to determine the irrigation needs of small sections of cultivated fields. http://www.physorg.com/news172221466.html Space & Earth Tue, 15 Sep 2009 08:30:02 EST news172221466 Antennas for the latest implanted medical devices are being developed by Queen Mary University of London and tested through a unique piece of kit at the UK's National Physical Laboratory (NPL). http://www.physorg.com/news171620414.html Technology Tue, 08 Sep 2009 09:30:01 EST news171620414 Several industries use wireless sensors, which can monitor chemical processes or equipment activity and then transmit the data over a wireless network. Still, many facilities that could benefit from the use of wireless sensors must continue to use a wired network instead, because the reliability, speed and security of the current generation of wireless sensors do not meet their needs. http://www.physorg.com/news170421006.html Technology Tue, 25 Aug 2009 12:10:37 EST news170421006 (PhysOrg.com) -- Improvised explosive devices (IEDs), the weapons of suicide bombers, are a major cause of soldier casualties in Iraq and Afghanistan. A group of University of Michigan engineering undergraduate students have developed a new way to detect them. http://www.physorg.com/news165069822.html Technology Wed, 24 Jun 2009 13:44:08 EST news165069822 One of the major sources of drinking water for south-east Queensland is now under the watchful eye of Australia's largest integrated intelligent wireless sensor network. http://www.physorg.com/news161427981.html Technology Wed, 13 May 2009 10:06:52 EST news161427981 (PhysOrg.com) -- Özlem Durmaz Incel, researcher at the University of Twente, the Netherlands, has developed a spectacular new method that enables wireless sensor networks to function up to ten times more efficiently. Networks based on this revolutionary method can be used for an extremely wide range of applications. They can, for example, be used for the surveillance of bridges, ports and distribution centres. They can also greatly increase efficiency in transport and logistics, for example in large ports. http://www.physorg.com/news160061305.html Technology Mon, 27 Apr 2009 14:29:10 EST news160061305 Today, humans perform visual inspections every two years of most of the nation's older bridges. But with a scarcity of inspectors and tens of thousands of bridges, that process can be long and laborious. http://www.physorg.com/news159116064.html Technology Thu, 16 Apr 2009 15:55:04 EST news159116064 (PhysOrg.com) -- A new, simpler programming language for wireless sensor networks is designed for easy use by geologists who might use them to monitor volcanoes and biologists who rely on them to understand birds' nesting behaviors, for example. Researchers at the University of Michigan and Northwestern University have written the language with the novice programmer in mind. http://www.physorg.com/news158255788.html Technology Mon, 06 Apr 2009 16:57:19 EST news158255788 (PhysOrg.com) -- Imagine a platoon of soldiers fighting in a hazardous urban environment who carry personal digital assistants that can display the location of enemy shooters in three dimensions and accurately identify the caliber and type of weapons they are firing. http://www.physorg.com/news157123967.html Technology Tue, 24 Mar 2009 14:33:19 EST news157123967 (PhysOrg.com) -- The picture of a future with wireless sensor networks-webs of sensory devices that function without a central infrastructure--is quickly coming into sharper focus through the work of Los Alamos National Laboratory computer scientist Sami Ayyorgun. http://www.physorg.com/news137855709.html Technology Wed, 13 Aug 2008 14:15:09 EST news137855709
