#Ultrasonic fingerprint sensor may take smartphone security to new level A new ultrasonic fingerprint sensor measures 3-D image of your finger's surface
Fingerprint sensor technology currently used in smartphones like the iphone 6 produces a two-dimensional image of a finger's surface,
A newly developed ultrasonic sensor eliminates that risk by imaging the ridges and valleys of the fingerprint's surface,

"After Apple announced a fingerprint sensor in their new iphone in 2013, it was inevitable that more would follow,
when the teams at the Berkeley Sensor and Actuator Center collaborated to initiate research into piezoelectric-micromachined ultrasonic transducers (PMUTS)."
"The basis for the ultrasound sensor is an array of MEMS ultrasound devices with highly uniform characteristics,
high-volume manufacturing processes that produce hundreds of millions of MEMS sensors for consumer electronics each year,
"Using low-voltage integrated circuits will reduce the cost of our sensor and open up myriad new applications where the cost, size,
and power consumption of existing ultrasound sensors are currently prohibitive.""Within the realm of biometrics and information security, the group's work is particularly significant,
"Our ultrasonic fingerprint sensors have the ability to measure a three-dimensional, volumetric image of the finger surface and the tissues beneath the surface--making fingerprint sensors more robust and secure."
"Beyond biometrics and information security purposes, the new technology is expected to find many other applications,
#Faster detection of hidden objects by terahertz sensor Called'Q-Eye',the invention senses radiation across the spectrum between microwaves and infrared, known as the Terahertz (THZ) region of the spectrum

who is also co-director of the Berkeley Sensor and Actuator Center.""It can be integrated into an ultrafast genomic diagnostic chip,
The next steps will be to implant larger meshes containing hundreds of devices, with different kinds of sensors,
and scale it up to include hundreds of elements and multiple types of sensors. One such sensor, for example, might be a airpin-shapednanowire able to measure electrical activity both inside and outside neurons.
It should be noted, of course, that the research is still in the early stages. Just because it works in mice doesn mean it will perform identically in humans.

In their tests, they were able to operate the camera up to 17 feet away, the temperature sensor up to 20ft away and the battery chargers up to 28 feet away from their router.
They also installed harvester-equipped temperature sensors 10 feet away from each router. Their results showed that the routers performed well,
and from neighboring routers while still sending enough power to the temperature sensors. The researchers hope that their technology will lead to battery-free sensors
and mobile devices that are powered continuously by Wi-fi routers. Check out the researcher full paper at Cornell University Library arxiv. via New Scientist via Digital Trends

#Revolutionary New High-speed Infrared detector Sees First Light The first prototype of a new generation of fast and very sensitive detectors has been installed successfully on the PIONIER instrument at ESO Paranal Observatory.
Unlike most of the commercially available detectors, RAPID can spot photons (light particles) of both visible and infrared light (wavelengths from 0. 4. 6 micrometres.
PIONIER was chosen as its interferometric combination of light requires a very fast detector to fight against atmospheric turbulence,
and the detector was exploited then immediately for purely scientific pursuits. t is an historic moment
he former detector on PIONIER is more than 20 years old and was considered still among the best of its type.
Every photon arriving into the detector is converted into many more than one electron, therefore easing its detection.
The avalanche effect is obtained without having to cool the detector to extremely low temperatures avoiding the use of a complex cooling system,
which considerably simplifies the detector packaging and operations. As an example, it took only two days for the team to install this brand new revolutionary camera inside PIONIER i
