Despite the initial excitement around voice-based smart devices, consumers are becoming increasingly nervous with the fact that these interactive devices are, by default, always listening, recording, and possibly saving sensitive personal information.

The Bracelet of Silence, created by a team from the University of Chicago can be worn and simultaneously disables microphones in its user’s surroundings, including hidden microphones, thereby enhancing and protecting individual privacy in the digital age.
