This Faraday fabric is some seriously high-tech stuff – it actually blocks 99% of wireless signals including cell, WiFi, Bluetooth, and GPS. The military uses this same copper and nickel-coated polyester material to create signal-proof enclosures. At 44x108 inches (3 yards), you've got plenty to work with for various projects.
People use this for everything from making RFID-blocking wallets to protect credit cards, to creating laptop radiation pads, or even lining rooms for complete signal isolation. The surface resistance is crazy low at about 0.05 ohms, and it works from 10MHz all the way up to 5GHz frequencies. If you're concerned about EMF exposure – maybe you're pregnant, have kids, or just want to reduce radiation – this fabric provides real protection. Just a heads up – it turns black when wet and hand washing is recommended over machine washing. For DIY privacy and protection projects, this is the real deal.
