Metamaterial
Sabrina Wallace - MISSING VIDEO - Metamaterial/thz biological sensing - part 2 of 5 Episode 1: Wireless power and body communication So, here we are on the effects of wireless power transfer on capacitive coupling of human body communication. Once again, there's the magnetic field that your cyclotrons and your CERN "happy fun time" are perturbating. Perturbating pressure sound using the air molecules around you. Field-programmable... riddle me this! So, it's a time-varying magnetic field. That's right, with deep learning. Uncooperative human activity recognition radar. That's right, "uncooperative", uh-huh. Putting everything that you do — bending, stretching, walking, running — into a feature extraction database for some other person to fire an electrical or magnetic signal on your face. And human activity recognition at scale... Remember, this is machine learning, you don't need a human sitting there watching. We let the air molecules watch for...
