#Fiber optic sensors developed for distributed temperature sensing The high-density fiber array sensors are suited to harsh environment processes
By combining Wistheat optical sensors with the Wistsense interrogator Proximion partners and customers can now design advanced systems for distributed temperature sensing.
The Wistheat series can be customized fully to meet any demands on sensor array length, separation of sensor elements or choice of wavelength.
In the standard configuration the optical sensors are packaged in a hermetically-sealed stainless steel tube with an outer diameter of 800 m. This configuration provides a thermal constant as low as 70 ms and long term stability up to 600°C (1,
100°F). All Proximion fiber optical sensors are based on the Fiber Bragg Grating technology with a standard spacing between sensing elements of 5mm.

Ossur's sensor-linked limbs meanwhile, have stood up to the abuses of everyday activity in Iceland and England (where Olafsson now lives.
And the surgery to implant the sensors was minimal. According to Thorvaldur Ingvarsson, an orthopedic surgeon and head of R&d at Ossur, the procedure took 15 minutes,
and each sensor required a single-centimeter-long incision. The tiny sensors (3 millimeters-by-80 millimeters) are powered by magnetic coils embedded in the socket--the cushioned,
hollow component that fits over a user's residual limb, and connects to the prosthesis.
there's no need to replace the sensors (unless they fail for other reasons). e believe this is a lifelong sensor,
says Ingvarsson. Another thing that differentiates this mind-controlled prosthesis is its simplicity. The sensors,
which were provided to Ossur by the Alfred Mann Foundation, don't have to be attached to specific nerves.
One major advantage of sensor-control, says Olafsson, is the way it redistributes your weight.

#Computer Chips Can Now Be made From Wood Not quite what we had in mindthe woods are lovely, dark, deep,
researchers announced the construction of computer chips made from wood. But don't expect to see hipsters advertising hand-carved artisan computer chips.
The wood product that the scientists are using is called cellulose nanofibril, or CNF. It is thin, flexible,
The researchers were able to use CNF as a substrate or base layer for electronic circuits in lab tests,
unlike a lot of the petroleum-based alternatives that manufacturers use to build the bases of modern computer chips.
"The majority of material in a chip is support. We only use less than a couple of micrometers for everything else,
"Now the chips are so safe you can put them in the forest and fungus will degrade it.
"It will be years before computers containing wood-based computer chips hit store shelves, but computers as fertilizer isn't a totally crazy idea.

Not only could it be used to create e readers that can be read like a magazine he says,
Wireless data transfer using light has already been demonstrated at blistering gigabit speeds using white LED LIGHTS.
Lasers are already an improvement over LEDS, because Li-Fi works by reading slight modulations of light,
and lasers can be tuned far more finely than LEDS. White light allows those signals to be transmitted over multiple areas of the color spectrum
For the study, Edgerton and his team used a technique called transcutaneous spinal cord stimulation where they placed electrodes on a patient lower back and sent a unique pattern of electrical currents through the electrodes.

#Scientists Create Liquid Metal Antenna By placing an electrical potential across the interface between liquid eutectic gallium and indium and an electrolyte,
or to contract by applying a negative voltage. sing a liquid metal that can change its shape allows us to modify antenna properties more dramatically than is possible with a fixed conductor,
The scientists created the tunable antenna by using electrochemical reactions to shorten and elongate a filament of liquid metal and change the antenna operating frequency.
Applying a small positive voltage causes the metal to flow into a capillary, while applying a small negative voltage makes the metal withdraw from the capillary. he positive voltage electrochemically deposits an oxide on the surface of the metal that lowers the surface tension,
Although antenna properties can be reconfigured to some extent by using solid conductors with electronic switches
which the antenna operating frequency can be tuned. or eutectic gallium-indium monopoles with lengths between 75m and 4m, the measured resonance frequency tunes from 0. 66 GHZ to 3. 4hz for a tuning
which is beyond the ratio obtained by switch or varactor-based antennas. urthermore, the measured total efficiency ranges from 41%to 70,
%which, while lower than a conventional monopole, presents a tradeoff between efficiency and versatility that is evident in most tunable systems. ur antenna prototype using liquid metal can tune over a range of at least two times greater than systems using electronic switches,
which the antenna and RF (reconfigurable radiofrequency) front-end must operate. his combination will create a real antenna design challenge for mobile systems
because antenna size and operating bandwidth tend to be conflicting tradeoffs. e
