Abstract
This study designs a biomechanically optimized wearable airbag system to prevent fall-induced injuries among the elderly. The system uses sensors to detect falls, deploying airbags with helium to cushion the body, specifically protecting the pelvis, femur, and spine. Simulations replicate fall conditions to evaluate the impact and injury reduction capabilities of the airbag, measuring forces and injury severity through established criteria like HIC and CTI. The results show that the airbag significantly decreases the risk of fractures and serious injuries during falls. The simulations are supplemented with real-world tests to validate the protective benefits of the airbag system. Both sets of data agree, confirming the airbag's potential to enhance elderly safety. These findings suggest that the proposed system could serve as an effective tool in reducing fall-related injuries, providing a new direction in fall prevention strategies for the aging society. This research contributes to the growing field of eldercare technology and opens avenues for further innovations in personal safety devices for the elderly.
