Doesn't matter; if it has a capacitive screen, a capacitive stylus will work. No pairing: It's a stick with no electronic components. Your device just thinks it's a very skinny finger, so that means zero pairing or fussing. No charging: A plastic or metal stick with a conductive foam tip doesn't require batteries.
The negative end of a battery (such as a AA, AAA, or AAAA) can also act as a stylus without any modification. However, if you would like to make it more sensitive, you can remove any insulating wrapping. A battery makes a great impromptu stylus. With the prevalence of hand help electronics we are rarely far from a battery of some kind.
A capacitive stylus works just as our finder does. It is a conductive object that disturbs the electric field on the touch screen and the touch screen registers it as a touch input. The tip of the stylus is made of conductive rubber material that allows the charges from the stylus reach to the screen.
Yes, some stylus pens are powered with a single-use AAAAA battery or a rechargeable battery. These are typically referred to as “active” styluses due to its electrical components. However, most stylus pens are actually “passive” and use capacitive technology without a battery at all.
The battery powers the internal electronics device, which are responsible for sending signals to the device it’s being used on. Without a battery, the stylus wouldn’t be able to communicate with the device, and would essentially be useless. So if you’re having trouble with your stylus, make sure to check the battery first.
A battery makes a great impromptu stylus. With the prevalence of hand help electronics we are rarely far from a battery of some kind. Probably the most interesting material that can be used to activate a capacitive touch screen is a sponge. It's cheap, effective and actually cleans your screen as you use it.
