There is almost no way to escape from surveillance.

It’s true—researchers from the Massachusetts Institute of Technology and the Rhode Island School of Design have created a microphone out of literal whole cloth. Their fabric microphone can detect and transmit sound waves, then convert them into electrical signals inside the cloth itself. Though the cloth can transmit sound and electrical signals, eventually, an external hardware is needed to process those signals. Their research is published today in the journal Nature.
