Personal Shielding-RF/EMI Shielding!
Personal Shielding-RF/EMI Shielding! We tend to think of RF/EMI Shielding in the electronics industry. RF/EMI can affect the function of electronic devices. Interference can reduce the operational efficiency of electronic devices. Human beings are also electronic devices. Many body systems are electronic in nature, potentially disrupted by RF/EMI. We live in a world with ever-increasing RF/EMI. Some of this RF/EMI is from nature. Natural RF/EMI includes lightning, solar magnetic storms, the auroras, and the Earth's magnetic field. The natural RF/EMI...

Metalized Textiles Questions-VTT has the Answers!
Metalized Textiles Questions-VTT has the Answers! V Technical Textiles, Inc. has the world's largest inventory of Metalized Textiles. VTT is the marketing and sales arm of our German partner, Shieldex. VTT prides itself in this strong relationship. VTT has input into the design of these unique textiles. Metalized Textiles were originally used in RF Shielding in automobiles. Their primary use was to stop RF interference with electrical components. In the last decade, uses for metalized textiles have grown exponentially. The...

Conductive Metalized Textiles-not just for Shielding!
Conductive Metalized Textiles-not just for Shielding! When conductive textiles were first developed, Shielding was their use. They were used to make sure car radios worked well. RFI and EMI were blocked, eliminating static hissing! They are still used to protect critical systems from RFI/EMI. They are also currently used in many different ways. Conductive Metalized Textiles-not just for Shielding! The medical sector uses conductive textiles as sensors. Human vital signs are detected by sensors and sent to recording devices. The human...

RF/EMI Shielded Curtains-Privacy and Separation!
RF/EMI Shielded Curtains-Privacy and Separation! In our lives, we use curtains for privacy, separation, and protection. RFI/EMI Shielded Curtains are used in the same way. RF Shielded curtains are made of conductive metalized textiles. These curtains block the passage of RF and EMI waves. One of the major uses of these curtains is in hospital telemetry areas. They effectively isolate the beds in a "shielded room". This assures that the proper information is transferred to the proper recording device. The...

RF/EMI Shielded Garments-Wearable Protection!
RF/EMI Shielded Garments-Wearable Protection! Our environment is full of Electromagnetic Radiation (EMR). Many of the sources of EMR "natural" and have always been present. The sun, atmospheric auroras, and the earth itself have electromagnetic fields. We are constantly exposed to these low-level electromagnetic fields. RF/EMI is a problem in electronic devices, decreasing performance. Electronic devices are shielded from RF/EMI using shielding materials. The shielding materials in electronic devices are often conductive metalized textiles. The metalized textiles block RF/EMI from passage to...

Ideas to Reality-Product Design and Development!
Ideas to Reality-Product Design and Development! Products don't just appear; they evolve from great ideas! The path from idea to final product has many steps. The first step is the idea, the cornerstone of the product. A person conceives a better way to accomplish a task. The challenge is to make the idea become a reality. In many cases, the inventor is only a "dreamer". He has no idea of how to make his "dream" a reality. Help often comes...

Electromagnetic Compatibility-when devices work smoothly Together!
Electromagnetic Compatibility-when devices work smoothly Together! Devices are like people, they work best when they're compatible. Electronic devices work best when they don't interfere with each other. Electronic devices can be interfered with in several ways. They can be "distracted" by RF interference emitted by nearby devices. This distraction is similar to a co-worker who is always talking. The background "noise" keeps work quality below its potential best. Devices that can be "distracted" are called "susceptible". The answer to susceptibility...

RF/EMI Shielding-the Key to EMC!
RF/EMI Shielding-the Key to EMC! Electromagnetic Compatibility Standards must be met prior to marketing devices. The device must perform well in a shared electromagnetic environment. It must not disrupt the performance of other nearby devices. It must not be disrupted by its environmental coworkers. The "potential disruption" is caused by RF/EMI outside of acceptable standards. In the US, the FCC determines these standards. In Canada, Industry Canada determines the standards. Europe requires the "CE" mark that represents compliance. Every country...
