Bill takes apart a smartphone and explains how its accelerometer works. He also shares the essential idea underlying the MEMS production of these devices.This video is based on a chapter from the EngineerGuy team's latest book Eight Amazing Engineering Stories (Learn more at http://www.engineerguy.com/elements)

thank you so much
Great narration and method of explanation
how does a smartphone gyroscop work?
From steam engines and horses to... Well... Today.
Insanity at the very least to out of this world at the most.
You learn something new every day! Too bad I'll be dead in two or three decades from now and never experience where this ride is taking us. ... then again, that might be a blessing.
so this accelerometer won't function properly if a force opposite to gravity is applied..
Now explain why viral videos are shot in vertical
so the entire accelerometer depends on mechanical movement and people thought smartphones were so advanced
But why use three pairs of combs all for one direction?
I liked accelerometers, but damn it knowing the science behind it makes them beyond amazing, this kind of tech blows my mind.
love the way you explain the things..
Can you explain why note 7 is a bomb in disguise
Im disappointed i thought maybe it was truely solid state and detected gravity particles.
It wont work in space
smartphones are so common that we don't appreciate the overwhelming level of technology in them
Why does this vedio sounds like it was made in the 90s or early 2000s?, maybe its the windows xp tour -like music.
mine is finicky LG G4 doesn't always work right away
Excellent! Thanks a lot for sharing! :-)
Micromirrors and Microengines, damn I'm about to graduate in the wrong engineering field. Those both sound like very interesting topics.
Engineers are really underrated
