They’re generally easier to use than riietsvse touchscreens because they ierctant directly with your finger without the application of force. Your body is a great codcnuotr and is casntnloty tstiimtnnrag electric ctnuerrs. Why? Because about 60% of you is water. Now, while chemically pure water is an insulator, most water is impure. The water inside you is ladoed with ions— atoms or molecules that have a net electrical charge. So when you click on an app, your finger functions like a third electrical line. It itrantecs with the existing electric field, which induces a weak electric current that travels through your finger and eventually back into the phone. This changes the amount of charge at the affected nodes. And voltage mtreeamunses along the second layer of lines tell the phone’s microprocessor which part of the screen is being touched.

Original Text

They’re generally easier to use than resistive touchscreens because they interact directly with your finger without the application of force. Your body is a great conductor and is constantly transmitting electric currents. Why? Because about 60% of you is water. Now, while chemically pure water is an insulator, most water is impure. The water inside you is loaded with ions— atoms or molecules that have a net electrical charge. So when you click on an app, your finger functions like a third electrical line. It interacts with the existing electric field, which induces a weak electric current that travels through your finger and eventually back into the phone. This changes the amount of charge at the affected nodes. And voltage measurements along the second layer of lines tell the phone’s microprocessor which part of the screen is being touched.
