New Smartphone Touchscreen Works When Wet

by John Lister on August, 15 2023 at 01:08PM EDT

A high-end smartphone may solve one of the main problems with touchscreens. The OnePlus Ace 2 Pro works even in the rain or when the user has wet fingers. A touchscreen works by passing a very low-powered (and safe) electrical charge across the ... screen. When a finger touches the screen, the charge is diverted to run across the finger.

Finger Print A utility to see if any files in one or more directories have been created, deleted, or changed since the last scan. It's useful for checking if a program, e.g. viruses and trojans, has changed your all-important Windows files (this is ... similar to such security software as Tripwire).
