Abstract
The invention relates to a knee joint motion intention recognition device based on flexible materials and an application method thereof, belonging to the field of force sensors and signal detection. The knee joint motion intention recognition device based on flexible materials comprises a thigh sheath, a lower leg sheath, a knee sheath fixing belt, a flexible material, a signal processing circuitboard, an air cushion fixing belt and a rubber sheath, wherein the thigh sheath and the lower leg sheath are all made of soft and elastic rubber material; the two air cushion fixing belts are respectively fixed on the thigh sheath, the lower leg sheath and the inner side of the leg; the thigh sheath and the lower leg sheath are connected with a rubber sheath, and the flexible material is PVDF piezoelectric film nested on the inner surface of the rubber sheath, and the air cushion fixing belts can be inflated to fit the muscles around the knee joint; and the signal processing circuit board is connected with the flexible material, and the air cushion fixing belt can be used for inflating and deflating. The knee joint motion intention recognition device based on flexible materials is convenient to wear, is suitable for people with different thigh thicknesses, can sense the movement consciousness of the knee joint of a user in a comfortable manner in real time, and has reliable practicability and good promotion value.
Description
technical field [0001] The invention relates to a flexible material-based knee joint motion intention recognition device and usage, and belongs to the field of force sensors and signal detection. Background technique [0002] The exoskeleton was first proposed in the 1960s, but because of its wide range of technologies and high conditions, it took until recent years to achieve more important technological breakthroughs. Nowadays, research on the application of exoskeleton equipment in rehabilitation training, body support, and breaking through physical limits has been widely concerned. Wearable exoskeleton devices can not only protect the operator related activities, but also be controlled by the wearer, helping the wearer to perform many sports. And among various rehabilitation trainings for recovering the motor function of the body, joint bending and straightening (elbow joints, knee joints, etc.) training has a huge impact on restoring the motor function of the human bod...
