Smart Nail Polish Study: Clear conductive coat turns nails into stylus tools; tech still in testing

Researchers have developed a clear nail polish that makes long fingernails conductive, allowing them to interact with capacitive touchscreens. This innovation uses acid-base chemistry to transfer electric charge, enabling taps and swipes. While still in early testing with concerns about longevity and safety, the concept aims to resolve the common frustration of using smartphones with long nails.
