Accelerometers

Definition

Accelerometers are sensors that measure the acceleration forces acting on an object, allowing for the detection of changes in movement and orientation. These devices play a vital role in protective equipment design and testing by providing accurate data on impact forces and motion dynamics, which helps engineers develop more effective safety gear that can absorb and dissipate energy during collisions or falls.
