Abstract: One or more embodiments of techniques or systems for impact detection are provided herein. In one or more embodiments, one or more sensors or sensor components may be embedded in an impact strip, helmet, article of clothing, apparel, accessories, etc. A sensor component may measure or take readings such as proper acceleration. These readings may be used to calculate velocities, force of a blow, speed of impact, etc. and notifications may be provided to appropriate parties when a force is determined to place a player or athlete at risk of injury. A database may be built from readings or measurements to determine different thresholds for different players (e.g., based on age, height, weight, etc.). In this manner, impact detection is provided.
