How does touch-screen work?
In: Technology
(I hope this doesn’t sound condescending or pretentious, I’m literally gonna try explaining like you’re five, not that this is an easy or intuitive thing to understand) Throughout our bodies we have nerves and they send electricity to our muscles and makes them move and flex, when we touch a touchscreen like on a smartphone it senses that electricity in our bodies, it’s not a lot of electricity at all so you don’t feel it, that’s why objects that don’t have any electricity or block electricity from reaching the screen, it doesn’t work. Older or lower budget touchscreens that you might find in a convenience store or sth have pressure sensors when you press down on them in a certain spot it senses that.
