A wearable vapor sensor could monitor diseases such as diabetes and hypertension by picking up airborne biomarkers exhaled

Fan is developing the sensor with Zhaohui Zhong an associate professor of electrical and computer engineering and Girish Kulkarni a doctoral candidate in electrical engineering.

Beyond disease monitoring the sensor has other applications. It would be able to register the presence of hazardous chemical leaks in a lab

To create their technology the researchers took a unique approach to detecting molecules. anoelectronic sensors typically depend on detecting charge transfer between the sensor

However these previous techniques typically led to strong bonds between the molecules being detected and the sensor itself.

The sensor can detect molecules in sample sizes at a ratio of several parts per billion.

These nanoelectronic graphene vapor sensors can be embedded completely in a microgas chromatography system which is the gold standard for vapor analysis the researchers say.

Or battery-free sensors embedded around your home could track minute-by-minute temperature changes and send that information to your thermostat to help conserve energy.

The nanoscale plasmon sensor used in the lab experiments is much smaller than other explosive detectors on the market.

Because of this the researchers are hopeful that their plasmon laser sensor could detect pentaerythritol tetranitrate or PETN an explosive compound considered a favorite of terrorists.

The sensor represents the latest milestone in surface plasmon sensor technology which is used now in the medical field to detect biomarkers in the early stages of disease.

The ability to increase the sensitivity of optical sensors traditionally had been restricted by the diffraction limit a limitation in fundamental physics that forces a tradeoff between how long

The amplified sensor creates a much stronger signal than the passive plasmon sensors currently available

which makes it easier to detect even smaller changes for tiny traces of explosives in the air. he sensor could have applications beyond chemical and explosive detection such as use in biomolecular research.

microwave refers to the readout frequency rather than the frequency at which the detectors operate.

MKIDS were developed first a decade ago by Mazin his Ph d. adviser Jonas Zmuidzinas professor of physics at the California Institute of technology and Henry Leduc at NASA s Jet propulsion laboratory.

In his lab at UC Santa barbara Mazin has adapted these detectors for the ultraviolet optical and near-IR parts of the spectrum.

The small amount of energy generated from these signals might power a sensor network in a remote location such as a mountaintop

In fact it should be possible to construct these power cells out of the excess silicon that exists in the current generation of solar cells sensors mobile phones

#Tiny water sensor embedded in plant stems Cornell University Posted by Krishna Ramanujan-Cornell on October 14 2013researchers are completing soil tests on a water sensor within a fingertip-sized silicon chip

They hope to mass produce the sensors for as little as $5 each. Crop growers wine grape and other fruit growers food processors and even concrete makers all benefit from water sensors for accurate steady and numerous moisture readings.

But current sensors are large may cost thousands of dollars and often must be read manually.

The new chip which is a hundred times more sensitive than current devices is fitted with wires that can be hooked up to a card for wireless data transmission

Such inexpensive and accurate sensors can be spaced strategically in plants and soil for accurate measurements in agricultural fields.

While growers can use the sensors to monitor water in soils for their crops civil engineers can embed the chips in concrete to determine optimal moisture levels as the concrete cures. ne of our goals is to try

the researchers came up with a magnetic sensor the size of a sugar cube that is also cheaper to manufacture

"Our sensors can be fabricated in parallel with techniques usually adopted for microelectronics, "says Kitching.""Moreover, while SQUID-based imaging systems require a large magnetically-shielded room to operate,

an imaging system based on our sensors could probably be operating in a much smaller (person-sized) shielded enclosure.

an array of over 306 SQUID sensors is mounted in heavy helmet-shaped flasks containing cryogenic coolants.

But the peculiar characteristics of the newly developed sensor might enable lightweight and flexible MEG helmets that contain much fewer sensors."

"We are targeting 32 sensors for our system right now, "says Kitching. The NIST sensor was used to measure alpha waves in the brain associated with a person opening

and closing their eyes as well as signals resulting from stimulation of the hand; the measurements were verified then by comparing them with signals recorded by a SQUID.

The sensor measured magnetic signals of about 1 picotesla (trillionth of a tesla), which is 50 million times weaker than the Earth's magnetic field."

#Inexpensive sensor measures ripeness of fruit As fruit matures, it releases a gas known as ethylene,

inexpensive ethylene sensors that could be used in places such as supermarkets. There, they could let shopkeepers know which batches of fruit need to sold the soonest

each sensor utilizes an array of tens of thousands of carbon nanotubes, which have had copper atoms attached to them.

the sensors are able to determine ethylene levels. As a result, the sensors can reportedly measure concentrations as low as 0. 5 parts per million for context

a concentration of between 0. 1 and one part per million is what is required generally for most types of fruit to ripen.

The sensors were tested on bananas, avocados, apples, pears and oranges, and were able to accurately gauge the ripeness of all of them.

Swager now envisions the sensors being built into the cardboard boxes used to store fruit, and equipped with radio-frequency identification chips that would allow them to transmit ripeness data to handheld reading devices used by shopkeepers.

Each sensor and chip combined should cost about US$1, as opposed to the $1, 200 or so that gas chromatography
