Radar captures subtle cellphone vibrations to eavesdrop on calls from several feet away

Something to look forward to: Researchers at Penn State University have demonstrated a new method of remote surveillance that enables the reconstruction of phone conversations using the subtle vibrations generated by a cellphone's earpiece. This technique, known as wireless tapping, uses millimeter wave radar sensors to detect and interpret these minute vibrations from distances of up to ten feet.
