Wearable foot bottom pressure acquisition device for artificial limb control

Abstract

The invention relates to a wearable foot bottom pressure acquisition device for artificial limb control, and the device s characterized by comprising an insole, and a pressure sensing module and a signal transmission module both integrated in the insole, wherein the pressure sensing module comprises four pressure sensors which are arranged in the insole; and the four pressure sensors convert detected foot bottom pressure signals into variable resistance values and transmit the variable resistance values to the signal transmission module for transmission measurement. The invention provides the wearable foot bottom pressure acquisition device for artificial limb control aiming at the insufficiency of control signals for smart artificial lower limbs and overcoming the existing technical shortcomings. The acquisition system realizes real-time acquisition of time sequence and distribution information of foot bottom pressure, and is capable of providing policy basis in a plurality of aspects such as gait phase, movement model and body gesture for the control decision of the smart artificial limb after processing the information, thereby assisting the smart artificial limb to well replace the lost limb of the disabled. The wearable foot bottom pressure acquisition device for artificial limb control can be widely applied to artificial limb control.

Description

technical field [0001] The invention relates to a sole pressure collection device, in particular to a wearable sole pressure collection device for artificial limb control. Background technique [0002] At present, the number of people with lower limb disabilities in my country has reached more than 9 million. With the aging of China's population structure and the frequent occurrence of natural disasters and safety accidents in recent years, the number of people with lower limb disabilities is still increasing. Prosthetics are widely used as an important tool for amputees to regain some of their ability to live. The development of new technologies has made people no longer satisfied with traditional lower limb prostheses that can only play a supporting role and enhance aesthetics. Intelligent lower limb prostheses are becoming a hot spot in rehabilitation research. Intelligent lower limb prosthetics can identify human movement trends based on human biological signals and ex...

Problems solved by technology

At the same time, the plantar pressure measurement method used for gait analysis in medical treatment, such as Chinese patent CN102090896, installs too many pressure sensors on the sole to obtain larger redundant information for comprehensive gait analysis, But there are the following problems: on the one hand, these redundant information are unnecessary for prosthetic control; on the other hand, too much information increases the pressure of intelligent prosthetic signal processing and the burden of control strategy formulation
