- 2015-06-18 Potential new breathalyzer for lung cancer screening
- Researchers from Chongqing University in China have developed a high sensitive fluorescence-based sensor device that can rapidly identify cancer related volatile organic compounds—biomarkers found exclusively in the exhaled breath of some people with lung cancer.
Their work, described in a paper published this week in the journal Review of Scientific Instruments, from AIP Publishing, demonstrates the potential of the device to be used as a breathalyzer for early lung cancer detection—possibly a safe and effective method of detecting cancer early that may save lives. - See Details

- 2015-06-18 Image sensors that behave like biological retinas
- Ever since the invention of the first camera obscura and the advent of photography in the 19th century, scientists have been fascinated by the use of light sensors to capture the world around us from the perspective of a man-made machine. Most recently, all eyes have been on image sensors relying on CCD or CMOS technology. These state-of-the-art camera devices can convert optical images into an electronic signal, and are used in applications for sectors including healthcare, automotive, media or security.

- 2015-06-18 New detection technologies for bacterial pathogens
- In FP7 jargon, RAPTADIAG is categorised as a 'small or medium-scale focused research project'. However, the past two years have seen the consortium turn a novel diagnostic test for bacterial meningitis into what is likely to become a full-blown set of sensor technologies for detecting bacterial pathogens of all kinds.
Whilst the sector has made some giant leaps over the past few years, much contemporary medicine still revolves around symptom-based treatments and costly diagnosis methods. In the case of 'bacterial meningitis' (BM), symptoms would usually develop within three to seven days after initial exposure if at all, as some people can carry the bacteria without getting sick. - See Details

- 2015-06-18 Safe public infrastructure… for life
- European researchers have developed a wireless sensor system to monitor the safety of large infrastructure. The new system will not only potentially save lives when the structure is old, it is reducing costs during construction, too.
Building structures can be affected by earthquake, landslides or construction defects from a previous era. But collapses in infrastructures, sometimes tragically resulting in deaths, can be avoided in future if early-warning sensors are placed on them right from the start. - See Details

- 2015-06-18 Fever alarm armband: A wearable, printable, temperature sensor
- University of Tokyo researchers have developed a "fever alarm armband," a flexible, self-powered wearable device that sounds an alarm in case of high body temperature. This armband will be presented at the 2015 IEEE International Solid State Circuits Conference, San Francisco, on 22-26 February, 2015. The flexible organic components developed for this device are well-suited to wearable devices that continuously monitor vital signs including temperature and heart rate for applications in healthcare settings.

- 2015-06-18 Wireless sensors make aircraft maintenance more efficient
- The FLITE-WISE project has developed new wireless sensors to facilitate the constant monitoring of European aircrafts. The new system, which is expected to bring both cost and weight down, will be commercialised within the next three years.
Some 842 million passengers took a flight in the EU-28 in 2013. With such mind-bending figures, it hardly comes as a surprise that airplane safety is continuously monitored, with rules that keep being reviewed and improved based on the latest technologies and scientific knowledge. In fact, it is safe to say that flying is one, if not the, safest existing forms of transport. - See Details

- 2015-06-18 Development of an image sensor for an infrared color night-vision camera
- Researchers have developed an image sensor for infrared color night-vision imaging in collaboration with Sharp Corporation (Sharp; Division Deputy General Manager & Unit General Manager, Sensing Device Unit, Electronic Components and Devices Division: Norihiro Hondo).
The developed image sensor is a new type of image sensor that realizes videos having high definition and high frame rate of the AIST night-vision technology that can record color videos even in darkness (Photo 1). Furthermore, the image sensor makes a video recording device smaller as the image sensor can be applied to single-plate method video recording. - See Details

- 2015-06-18 Radar sensors support parking management
- Siemens is researching the use of sensor networks in an advanced parking management solution that will hopefully counter the increasing parking space crisis in cities. The online magazine Pictures of the Future reports about this solution, which will be used this spring for the first time in a pilot project in Berlin. In this concept, sensor networks collect information about the parking situation in cities. The information is forwarded to the drivers in order to make it easier for them to find unoccupied parking spaces.

- 2015-06-17 Borrowing from whales to engineer a new fluid sensor
- How can a humpback whale and a device that works on the same principle as the clicker that starts your gas grill help an unmanned aerial vehicle (UAV) fly longer and with more stability?
Well, it all starts with biological structures called tubercles that the whale uses for its unique maneuvers in the ocean. Felix Ewere, a doctoral student at The University of Alabama in Huntsville (UAH), made a mechanical version of the wavy-looking biological structures and attached it to a piezoelectric energy harvester. The piezoelectric principles the harvester uses convert mechanical action into electricity just like the red piezoelectric button on your gas grill does. - See Details

- 2015-06-17 Pens filled with high-tech inks for do-it-yourself sensors
- A new simple tool developed by nanoengineers at the University of California, San Diego, is opening the door to an era when anyone will be able to build sensors, anywhere, including physicians in the clinic, patients in their home and soldiers in the field. The team from the University of California, San Diego, developed high-tech bio-inks that react with several chemicals, including glucose. They filled off-the-shelf ballpoint pens with the inks and were able to draw sensors to measure glucose directly on the skin and sensors to measure pollution on leaves.

- 2015-06-17 Will next-generation wearable sensors make us healthier?
- There is certainly no shortage of headlines on wearable sensors these days. "A contact lens measures your glucose level." "New electronic tattoos could help monitor health during normal daily activities." A "headband can read your brainwaves." Numerous wearable sensors are currently on the market that can monitor body data including activity and sleep, heart rate, galvanic skin response, and electrocardiogram (ECG). But are these wearables making any difference? Are they actually making us healthier?

- 2015-06-16 New research reveals low-oxygen impacts on West Coast groundfish
- When low-oxygen "dead zones" began appearing off the Oregon Coast in the early 2000's, photos of the ocean floor revealed bottom-dwelling crabs that could not escape the suffocating conditions and died by the thousands.
But the question everyone asked was, "What about the fish?" recalls Oregon State University oceanographer Jack Barth. "We didn't really know the impacts on fish. We couldn't see them." - See Details
