What are Faraday Cages and How are they Used?

Faraday Cages are enclosures first researched by Benjamin Franklin in 1755, but mostly attributed to the work done by Michael Faraday in 1836.  Essentially, a Faraday Shield is an enclosure made of a continuous covering of walls, ceilings, and floors by a conductive metal that is used to completely block Electromagnetic Fields from entering the inside of the enclosure by spreading the current over the outside of the enclosure.  In contrast, a Faraday Cage, which involves the use of a...

Forensic Evidence (Faraday) Bags-Keeping Electronic Evidence Secure inside a Faraday Cage

We are all aware of the proliferation of electronic devices that we use in our daily lives,  in fact, most of us have several electronic devices that we use regularly.  These devices can be our cell phones, which have essentially become miniature computers that keep track of our appointments, finances, email, phone calls, and text messages.  Additionally, we have our computers, tablets, and PDA's.  All of these devices help us to keep our lives in order by making our information...
The Benefits of RF Shielded Garments!

Throw away your Tin Foil Hats, RF Shielded Clothing is Stylish and Comfortable Now!

In today's electronic device driven world, the human body is exposed to Electro-Magnetic Fields (EMFs) at an ever-growing rate.  The sources of the EMFs are largely man-made, delivered to us via our wireless devices including:  cell phones, Wi-Fi, Bluetooth devices, computers, cellular towers, high tension power lines and so many others.  EMFs are not visible to you, you can't see them, touch them, feel them, taste them, or smell them.  In fact, we are humans, yet the cells of our...

Compliance Test Tension? An RF Shielded Enclosure by V Technical Textiles, Inc. can Ease the Stress!

We all know that final EMI Compliance Testing can be a tense time.  Time has been invested in development, design, prototyping, and now it is time to find out if your device is compliant with applicable ElectroMagnetic Compliance (EMC) standards.  You drive the three hour trip to the testing site on your appointed day.  Of course, the line has formed and "they're running a little behind today", so you wait for your turn.  You hand your device over to the...

Size Problem? Large or Small, VTT can Help with your EMI Testing Needs!

Electronic devices come in many sizes, whether your device is the size of a cubesat, an automobile, military vehicle, or a spacecraft, V Technical Textiles can help you with your EMI Testing needs by providing you with one of our portable RF Shielded Testing Enclosures, specially designed for your testing needs. EMI testing follows two basic tests that determine if a device is fit to work in an environment with several types of electronic devices in it. The first test is...

“Hardening Structures”-Protecting our Country’s Vital Electronics-Based Systems!

ElectroMagnetic Pulses (EMPs), transient electromagnetic disturbances, evoke the Orwellian thoughts of nuclear explosions that are capable of short-circuiting a wide range of electronic equipment, including computers, satellites, radios, radar receivers, and even traffic lights, plunging the world into the "electronic dark ages".  Though a nuclear weapon is the most commonly thought of cause of an EMP, they can also be caused by solar flares, a close lightning strike, or a massive powerline short circuit.  The damage to electrical equipment can...

Portable RF Shielded Enclosures Provided Work from Home Applications During Covid-19

When Covid-19 hit North America in March, it closed down a lot of our businesses, but many businesses and individuals were able to continue to do work from home or other remote locations during the quarantine/social distancing period of this pandemic.  The "Work From Home" #wfh group, were often able to continue their work with the use of RF Shielded Enclosures and pouches. One didn't need to be in the electronics development business to benefit from these enclosures.  Government and Business...

The Constant Increase of Electronic Devices makes the Shielding Industry Very Important in Achieving EMC!

We have more electronic devices than ever before in this world, each of them adding to the invisible cloud of E-Smog that surrounds us all.  More of these devices are being developed all of the time, with the development in cellular infrastructure for the 5G and 6G communications systems....yes, I said 6G!!!  That doesn't include the aerospace and automotive industries as today's aircrafts and automobiles are essentially controlled and driven with the aid of complex electronic devices and the consumer...
Conductive Textiles in Healthcare-Medical Advancements!

A New use for Conductive Yarns, Embroidered Sensors and Electrodes!

If you think about it, a sensor is a conductive material that is attached to the skin and used to transmit readings of biometric information such as heart rate, brain activity, and other bodily functions through a wire to a recording device, giving your health professional a good idea of how your body is working.  An electrode is like a sensor as it is made of conductive material and attached to the skin, but instead of transmitting information away, it...

Silverized Fabrics, Comfortable to Wear and Beneficial to Your Health as Well!!

V Technical Textiles, Inc. provides a line of clothing made with Silverized knits and fabrics.  These conductive metalized textiles make the clothing more comfortable, as the silver is a great conductor of heat.  This conductivity spreads the natural body heat that it absorbs throughout the surface of the garment, creating an even and balanced body temperature, lessening the presence of "hot spots and cold spots", and making the wearer feel more comfortable.  This "balancing" of the body temperature increases circulation,...
