hey everybody I'm Chris book and this is the s-pen sure you know what it does but do you know how it does it let's find out it seems simple enough take out the s-pen right on the screen and there you go but it's a little more complicated than that for example there's a button on the S Pen that's gonna need power and where does that power come from how does this all work together well let's break it down okay I have an admission to make I can't literally break the S Pen because then I wouldn't be able to use it what I can do is tell you and show you how it does what it does first things first where does the S Pen get its power from actually a circuit and a few other pieces of hardware laid out in a grid sit behind the screen and generate an electromagnetic field just so you know that's about as technical as we're going to get as soon as the s-pen gets in range it starts to pick up that electromagnetic field this by the way is right around where you'll start to see the hover icon appear on the screen now inside the s-pen near the front is a tightly wrapped coil that channels the energy from the field and uses it to power its own circuit now here's where it gets really interesting the screen has nothing to do with using the s-pen that's right nothing it's possible that you might have noticed this before but if you press the tip or nib of the s-pen while it's close enough to the screen it acts exactly as if you would just tap the screen that's because the nib is basically another button on the s-pen this one just happens to be pressure-sensitive when you press down on the nib you're basically telling the device that you're touching the screen even if you aren't you can draw like this use it to navigate the Play Store or anything else this isn't really useful of course it's just a nice demonstration you can see here that even though the S Pen has no contact with the screen it still picks up what I'm drawing on the business card this might not seem like a big deal but it does show that you can use a heavy-duty screen protector or case with your note 2 for example and not have to worry about the S Pen working incorrectly that my friends is how the S Pen works as you can see we are clearly living in the future now I didn't want to go overboard for the video but if you want to know more the full article can be found at Android Authority calm the link can be found in this video's description right below here's the thing this is kind of the first time we've done a video like this so we really want to know what you think you like the video do you want to see more if you do do you have any ideas for what you'd like to see us break down let us know in the comments we really do appreciate any and all feedback we add new videos to our channel all the time so if you want to make sure you don't miss a thing make sure to subscribe I'm Chris Wolfe from Android Authority and thank you for watching
