I love this! A good possibility in preventing people from locating your whereabouts 24/7 or listening in. Anechoic chambers were my peace zone - and this is like peace of mind everywhere you go. There was a time I used to carry copper tape with me all the time to cover my cards and made a pouch out of it. And i used to stick ferrite beads at the edge of all cables . And once I made loop antennas from old RF cables, connected them to a handheld signal analyzer to detect how much signals that's around me, and I found 400 MHz harmonic jamming my car alarm near a transmission plant. I think this could help detect hidden cameras in hotels or Airbnbs as well, as they typically use RF bands to transmit video signals. Would be cool to get a signal generator, turn on satellite modulation signals and measure reflections and see how many signals it suppresses (or see what signals you can pick up near you) but it needs a satellite dish to detect. Actually if you have a sign gen and an analyser and some loop antenna, check out your radiation from laptop, your phones at higher frequencies. It's one reason why I stopped using my laptop on the lap - because Cispr tests didn't test high freq harmonics. This innovation is very cool, the paranoid me appreciates it.

btw, your friend can sell this to people who wear pacemakers as well - it will be a good protection gear against EMI signals. A statement to correct on the above - the regulatory test is up to 1.5GHz (this is standard practice) and it attenuates 70dB which is really good, keeps your harmonics low. However satellite signals are typically 1GHz - 40GHz. So if you want to make sure you are blocking anyone from detecting you or hearing you, you can just test it on your own. Also really love the conductance testing - so much possibility.

Why not put the phone in a drawer if it's a portal to a war and I must robotize myself in order to survive?
Unfortunately electrical shielding can also act as containment and provide additional paths for EM waves to resonate. I prefer to simply stay away from high-power EM sources like in cities and near radio or cellular towers. Keep your phone on airplane mode, when using cellular locate the phone at least 10' away (or a minimum of an arm's length) and use a bluetooth headset for phone calls, turn off NFC when not using it, only use wifi at home, turn down your wifi router's power level to the minimum necessary, locate your wifi router away from bedrooms, kitchen table and the living room, plant trees and shrubs around your house to absorb EM, when replacing your roof make it steel or aluminum panels and be sure its well grounded with braided copper straps (tin foil hat for your house), avoid metal siding as it can act like a "microwave oven", locate your house in a topographic depression, and move out of the city. EM is only one of many carcinogens and endocrine disruptors that you are exposed to in densely populated areas.
I fucking hate fashion people. This shit is ugly as fuck. Give me something that looks cool in the woods please.

These are some great tips! I too have become more comfortable using my phone with a headset. I'd dig a geodesic dome that scatters the waves =) I don’t think resonance will impact heavily tho - it’s attenuating 70dB signals - your harmonics and TOIs are gonna be tiny tiny fellas. Even anechoic chambers are coated with a good conductance (that and it’s absorption foams). I also love the conductance capacity - energy inducing fabrics are game changers. I am curious on shorter wavelength attenuation results - I’d reckon this materials are solid blockers until 12GHz which is incredibly decent - it may not cover your terahertz and gamma rays but that’s expected as you need concrete and lead for that. I am still a little paranoid on Bluetooth esp class A hitting 20dBm. Doing a bit of deep dive on that. If I have anything on me that receives signal, I need it to absorb and emit least amount of radiation, one that is safer than taking a walk in the city kind
Do you think, people will put the phone in the pocket and there will be no signal in those cloths.
I had given up cell phone for good before you got me started (again) with #nostry tweets .. and now you want me tin foil my bald head .. good 😊

Is M.I.A. going to join Nostr? I've already messaged her several times.

Was looking at the test again - the material is conductive, not energy producing - which makes perfect sense. Typically when resistance is measured, you don’t connect it to any power source because the multimeter will apply a small voltage to the resistor and measure the current flowing through it to calculate resistance (V=IR). The metal composition can cover up to 12GHz which is pretty decent. Higher signal will have lower power and requires amplifiers and mixers - hence if the concern is bodily protections then its perfect because it will bounce off.
