We've reported before on the potential for Anti-Wifi paint but it turns out those researchers have done it. Honestly, I'd prefer a Wi-Fi enhancing paint. Would you use Wi-fi paint to secure your home network? Do you see any other uses?
Potential uses include keeping your wireless network secure, blocking phone calls during movies, shielding hospital rooms or aviation cockpits from unwanted electromagnetic signals and radiation and making clothes that protect people from electromagnetic waves.
