In-ear accelerometers

In Simple Terms

F1 drivers must wear in-ear accelerometers during races and certain sessions to measure the physical forces and impacts they experience. This safety data helps teams and the FIA monitor driver wellbeing and collect valuable information about crash impacts and extreme cornering forces.

• Drivers are required to wear FIA-approved in-ear accelerometers during all race sessions
• The device measures G-forces experienced during acceleration, braking, and impacts
• Data collected is used for safety research and to assess driver fitness to continue racing after incidents
• Teams must ensure devices are properly fitted and functioning before sessions begin
