Electrical engineer Todd Coleman at the University of California at San Diego, for example, is using super-thin flexible electronic “tattoos” to read brain wave activity in a non-invasive way and use that data to control machines.
The small, flexible devices could also be put on the throat and behave as subvocal microphones through which people could communicate silently and wirelessly and perhaps improve speech recognition in smartphones.
