Cat Girl Dreams Are Not Unattainable: Japan's Necomimi Brainwave-Controlled Moving Cat Ear Headband

The Necomimi by Neurowear (Japanese: cat ears) is essentially a headband with fake cat ears (宅男们，其实可以偷偷在家戴的哦！). It has built-in sensors that can detect the wearer's brainwaves. Depending on the brainwave activity, the ears can twitch, wiggle, and even droop, letting people around you know your current mood.
