Wearable tech that turns a user's skin into loudspeaker made
Researchers in South Korea have developed a wearable technology that can be attached to a user's skin and work as a loudspeaker. The technology consists of ultrathin, transparent, and conductive hybrid nanomembranes with nanoscale thickness. The nanomembrane loudspeaker operates by emitting thermoacoustic sound through the oscillation of the surrounding air brought on by temperature differences.
