Finding the Accelerometer. Now I just need to do a little drawing. I know the distance from the center to the accelerometer in both orientations. Here is a diagram showing where those two curves ...

Researchers at Georgia Tech and MIT have developed a proof of concept to demonstrate that it is possible to record a computer user's keystrokes using an iPhone 4's accelerometer. The researchers ...

With the introduction of higher integration and more accurate accelerometer products, system designers still have a need to understand how parts are calibrated; ... A simplified diagram of the 4-point ...

Their research (DOI: 10.1038/s41378-024-00826-x), published in Microsystems & Nanoengineering on March 5, 2025, introduces a MEMS accelerometer featuring an advanced anti-spring mechanism.

Accelerometer - definition The accelerometer is a built-in electronic component that measures tilt and motion. It is also capable of detecting rotation and motion gestures such as swinging or shaking.

So here is a diagram of my iPhone (looking at it from the back). Pretty sure that's where the sensor is located. Now I just need to take apart my phone to verify this result.

Objective Self-reports of physical activity (PA) have been the mainstay of measurement in most non-communicable disease (NCD) surveillance systems. To these, other measures are added to summate to a ...
