  • Title: A wearable airbag to prevent fall injuries.
    Author: Tamura T, Yoshimura T, Sekine M, Uchida M, Tanaka O.
    Journal: IEEE Trans Inf Technol Biomed; 2009 Nov; 13(6):910-4. PubMed ID: 19846379.
    Abstract:
    We have developed a wearable airbag that incorporates a fall-detection system that uses both acceleration and angular velocity signals to trigger inflation of the airbag. The fall-detection algorithm was devised using a thresholding technique with an accelerometer and gyro sensor. Sixteen subjects mimicked falls, and their acceleration waveforms were monitored. Then, we developed a fall-detection algorithm that could detect signals 300 ms before the fall. This signal was used as a trigger to inflate the airbag to a capacity of 2.4 L. Although the proposed system can help to prevent fall-related injuries, further development is needed to miniaturize the inflation system.
