How Sound Waves Can Fool MEMS Accelerometers (and Other Ways to Dupe Sensors)
Sensors can do just about anything and they're reliable, but just how reliable? Accelerometers, activity trackers, and LIDAR sensors are just a few we'll go into and show just how the sensors can be fooled.

Have you ever wondered just how well your sensors work? The functionality of many devices relies on sensors receiving input from the world around them. But how reliable are these sensors in the first place? It turns out that you can pull a fast one on more sensors than you might realize.
Fooling Accelerometers in Smartphones with Sound Waves
The accelerometer in your smartphone can be altered using sound waves, which was discovered by Timothy Tippel, Kevin Fu, and other engineers at the University of Michigan's Computer Science and Engineering Department.
