Scientists Develop Clear Nail Polish That Works With Touchscreens
Researchers are developing a clear nail polish that would allow people with long nails to use touchscreens comfortably. After testing dozens of formulas, they found that combining taurine and ethanolamine gives nails enough electrical charge for screens to detect a touch. The innovation aims to eliminate the awkward workaround of tapping with fingertips instead of nails.
Using a smartphone with long nails can be frustrating, forcing people to awkwardly tap with their fingertips instead of their nails. Now, researchers are working on a clear nail polish that could change that by turning fingernails into touchscreen-friendly tools. By experimenting with dozens of formulas, they discovered that combining common compounds like taurine and ethanolamine can help nails carry just enough electrical charge for screens to detect a touch.
