    Area of Science:

    • Gerontology
    • Biomedical Engineering
    • Wearable Technology

    Background:

    • Elderly individuals are susceptible to falls, leading to significant physiological and psychological distress.
    • Timely and proper emergency treatment is crucial but often delayed after falls.
    • Existing fall detection methods lack routine commercial viability.

    Purpose of the Study:

    • To design and develop a wearable fall detection device for the elderly.
    • To implement a wireless monitoring system for activity data within a community.
    • To improve emergency response for accidental falls in older adults.

    Main Methods:

    • A wearable device incorporating an accelerometer sensor was developed.
    • Wireless technology was used to transmit activity and location data to a remote server.
    • A three-stage detection algorithm was employed, using a Sum-vector of all axes (SA) threshold of 2.5 g.

    Main Results:

    • The system achieved an accuracy rate exceeding 95% in distinguishing falls from other activities.
    • A threshold value of 2.5 g for the SA was identified as effective for fall detection.
    • The wireless monitoring system facilitated real-time data transfer for downstream processing.

    Conclusions:

    • The developed wearable fall detector is accurate, low-cost, and user-friendly.
    • The system demonstrates potential for widespread adoption in daily life for enhanced elderly safety.
    • Further improvements could lead to even more common use of such fall detection devices.
