Concussion Dosimeter (CD)

Capability Summary: Wearable sensor systems that capture and/or record blast and impact events to inform the need for Traumatic Brain Injury (TBI) assessment and satisfy National Defense Authorization Act (NDAA) requirements (Section 734 of NDAA FY 2018; Section 717 and 742 of NDAA FY2020; Section 735 of NDAA 2023). TBIs are common in Warfighters, with 492,1671 occurring from 2000 to 2023. This effort develops wearable sensors for the two leading causes of TBI (blast overpressure and impact) to help mitigate, document, and improve response to potentially concussive events.

The CD effort will develop sensors that:

• Record and provide feedback for potentially concussive events (PCE).
• Allow tracking to monitor effects of chronic exposure to PCE.
• Use automated data collection to integrate with information platforms, including the electronic health record.
• Enable mitigation of unnecessary risk of TBI without degrading quality of training or effectiveness in combat.

Impact: The CD capability maintains Warfighter readiness and lethality by reducing risk of TBI by providing early indicators of blast overexposure and impact, helping units prevent unnecessary exposures, and identifying Warfighters in potential need of medical assessment. It enables Warfighters and medical personnel to better respond to potentially concussive events, enabling readiness.
