Abstract

This invention discloses a gait monitoring device for Parkinson's disease and its operating method. The monitoring device includes a gait detection mat, comprising a first power generation layer, a second power generation layer, and a support layer. The support layer is disposed between the first and second power generation layers to leave a gap between them. The first and second power generation layers have opposite polarities. An electrical signal detection device is electrically connected to the first and second power generation layers via wires. A controller is electrically connected to the electrical signal detection device and is used to analyze the current changes detected by the device. This application, by using a gait detection mat, eliminates the need for adaptation adjustments based on the user's foot shape, making it versatile. Furthermore, the gait detection mat does not require an additional power supply; it generates electrical signals through the electrostatic induction effect between the first and second power generation layers, thereby detecting the user's gait and providing a diagnostic basis for Parkinson's disease.
