The most common of these THz source technologies are photoconductive switches comprised of a semiconductor material and two parallel metal strips that act as electrodes through which a large voltage is applied externally.

When a short, or sub-picosecond, pulse of light is incident between the strips, electrons and holes created by the light pulse are accelerated, leading to the generation of a broadband electromagnetic pulse with the frequency spectrum centered in the THz range

The spacing between the metal strips can be as small as microns, and fabrication of such a microelectronic device is therefore costly and complex.

Moreover, the external bias voltage can be limited by dielectric breakdown in air, restricting the amount of energy in each THz pulse.

In an exciting new development, researchers at the U.S. Army Research Laboratory’s Adelphi Laboratory Center in the Sensors and Electron Devices Directorate including Dr. Michael Wraback, Dr. Grace Metcalfe, and Dr. Paul Shen, have developed and successfully tested new ways of generating THz emissions that do not rely on these unfavorable features, and have promising futures in both biomedical and security applications.

“We wanted to exploit the area between microwaves and infrared in order to gain an advantage that our adversaries do not have,” Wraback said.

ARL offers three different alternatives to the traditional THz approach that do not require the use of metal contacts and externally-applied voltage, through three different ARL patents.

Through these alternatives developed, ARL researchers believe that current THz technologies can be improved and have a very promising future in both the biomedical field and in security applications.

THz-rays are nonionizing, meaning that they pose no harmful threat to biological tissues–unlike x-rays, for example–and can pass through thin layers of low-water-content materials such as clothing, paper, wood, plastics and ceramics.

As a result, ARL researchers believe their new THz source could be used to “see” high-resolution changes in the density of biological tissues near their surfaces, with the possibility of ultimately enabling handheld devices to identify potentially harmful anomalies during routine screening, hopefully reducing the time between initial detection and full examination.

In addition, the ARL technology could be used to develop safer, accurate, noninvasive and more cost-effective ways to screen for malignancies, such as a simple breathalyzer test, and improved detection of tooth decay.

ARL researchers also stated that their new THz technology has great potential in the biomedical field in terms of pharmaceutical practices.

“THz technology is also very prominent in the pharmaceutical field, especially in the area of pill coating,” said Shen.

THz technology allows for the determination of the integrity of the structure of pills through the imaging of their coatings, which is a significant benefit for pharmacists.

In terms of security applications, THz has potential investigative uses since many materials give off distinctive spectral “fingerprints” when exposed to THz radiation, such as explosives, chemicals, medications and illegal narcotics.

In addition, due to its special nondestructive nature, THz radiation can be used to distinguish between visually-similar materials, a capability ideally suited to quality control in applications ranging from food preparation to inspection of integrated circuit chips

https://www.officezone.com/aiehandc.htm – Hand sealers, sometimes called handheld bag sealers, are great to have for packaging and sealing plastic bags. What do you do if you bag has excess plastic? If you have a standard hand sealer, you have to cut it off using scissors. If you need to cut plastic off of a lot of bags throughout the day, scissors can be tedious. This is why you need to use a handheld bag sealer with a build in cutter. These AIE hand sealers all include a cutter and can be used to seal a wide variety of bags. These sealers range in sealing length from 8″ up to 16″ and produce sealing widths from 2mm up to 5mm, depending on the model. Using these handheld bag sealers is easy. Simply adjust the machine, place the open end of the bag into the sealer and pull the arm down. Once the sealing is complete, pull the cutter lever and slit off the excess plastic. These sealers are incredibly popular. Buy yours today!
