Human-Powered Brain Scanner

Apparently upset that their creations haven't destroyed humanity yet, scientists are now building machines directly from movies where we've been enslaved. The Holst Center has developed a device that harvests human body heat to power a brain-scanning sensor system. They call it a "battery-free wireless EEG", presumably because being honest and calling it "Agent Smith" would lead to legal trouble (at least until Sentinel units destroyed the Warner Bros lawyers). This is the latest in a series of such brain scanners, as the developers realize that a brain scanner doesn't just have to work: it has to be something that people are prepared to put on their head. Previous iterations were much bulkier and required a large array of thermoelectric panels on the forehead - so as well as neck pain, the user looked like a particularly fashion-unconscious Raelian. A sensor that picked up nothing but the brainwaves of "shame" and "embarrassment" wasn't much use - you can get the same effect by forcing someone to wear sweatpants - so a new hybrid power technology was developed.
