The engineer shows you how the phone's accelerometer works, with video-assisted instructions

Some mobile phone players and enthusiasts are interested in the components of some mobile phones and even want to know how they work. Now, both mobile phones and tablets are basically built-in acceleration sensors to identify the direction of the device's rotation. Bill Hammack, an engineer from Illinois University, briefed us on how this acceleration sensor works and is not a tedious sermon, but an animated film to help explain it.

Bill Hammack used Android and iphone to illustrate the basics of the three-axis accelerometer, but the iphone was the main concept, and if it was stationary, it would be measured at 1g, then the acceleration would be assigned to three axes "x, Y, z". The relative angle between the three axes and the level can be obtained by calculating the different numerical sizes. At the same time, the three-dimensional diagram shows how MEMS micro-electro-mechanical system can be placed on a certain shape of silicon wafer, in order to meet the needs of our mobile phone hardware function, which involves the microelectronics technology and machinery engineering technology, sounds like a physics enthusiast's favorite course. Hammack says it's one of the coolest parts of a smartphone, and the content is pretty engaging, and you'll probably find a way to agree with him after watching the movie.
