| Abstract: Falls are one of the main causes of death in the elderly due to injuries, and immediate rescue after falls can alleviate the serious consequences caused by falls. Meanwhile, with the development of micro-electro-mechanical technology, research on fall detection based on wearable devices has gradually become the focus of scholars. In order to systematically review the research progress of fall detection based on wearable pressure sensors, this paper firstly proposes to analyze the principle and characteristics of wearable pressure sensors acting on fall detection based on the physiological structure of the human foot. Secondly, based on the framework of the fall detection system, a detailed overview is given of the setting and system integration methods of pressure sensors, special processing methods of pressure data, and different judgment methods of fall detection models. Finally, existing achievements are classified and compared, which provides reference for subsequent research. |
