Background:

Falls pose significant health risks to the elderly.
Timely fall detection is essential for preventing secondary injuries.

Purpose of the Study:

To propose a novel wearable-sensor-based fall detection algorithm.
To enhance the accuracy and speed of fall detection in elderly individuals.

Main Methods:

Developed a Patch-Transformer Network (PTN) incorporating convolution, Transformer encoding, and linear classification layers.
Utilized multi-head self-attention for global feature learning and Global Average Pooling (GAP) for feature-category correlation.
Tested the algorithm on the SisFall and UnMib SHAR public datasets.

Main Results:

Achieved high accuracy rates of 99.86% on SisFall and 99.14% on UnMib SHAR.
Demonstrated rapid detection times of 0.004 s and 0.001 s, respectively.
The PTN model exhibits fewer parameters and lower computational complexity.

Conclusions:

The proposed Patch-Transformer Network (PTN) offers a timely and accurate solution for wearable-sensor-based fall detection.
This method is vital for improving the safety and well-being of the elderly population.
