more or less same crap is achieved via radiomyography from your local telecom towers. down to deciphering your inner monologue

``` The envisioned application is radiomyography which aims to detect muscular activity by the means of electromagnetic waves coupled into the human body. The paper concludes that it is possible to detect changes in the thickness and the properties of the muscle solely by evaluating the reflection coefficient of an antenna structure. The ability to detect these changes strongly depends on the antenna type. ```
``` Unvoiced or silent speech recognition recognizes speech by observing the EMG activity of muscles associated with speech. It is targeted for use in noisy environments, and may be helpful for people without vocal cords, with aphasia, with dysphonia, and more. ```
radiomyography ~= form of electromyography
