Problems solved by technology

Although this kind of prosthesis is economical and affordable, its functions are simple, and it often cannot meet the needs of patients other than snatching.
Electronically controlled advanced prosthetics can perform more and more complex movements, but they are expensive
Bioprosthetics under study use complex pattern recognition algorithms to interpret muscle biosignals (EMG) on muscle nerves to control robotic arms. These robotic arms are more powerful, but the systems are also more complex

Embodiment Construction

[0031] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] A bionic prosthesis based on bioresistance measurement mainly includes: a bioresistance measurement module, a signal processing control module and a manipulator, the signal processing control module sends an excitation signal to the bioresistance measurement module through a cable, and under the action of the excitation signal, the bionic prosthesis The resistance measurement module measures the bio-resistance, and transmits the measurement data back to the signal processing control module. The signal control processing module analyzes the distribution of bio-resistance of the measurement data and interprets the movement mode of the muscles. The control comman...

Abstract

The invention discloses a bionic artificial limb based on biological resistance measurement. When the brain controls the muscles or bones to move, changes of biological resistance are measured in real time through a wrist strap; then, palm motions corresponding to the changes are interpreted through a signal processing control system; then, a machine hand is operated to achieve the brain control purpose. By adopting the biological resistance measurement/imaging technology, complexity of an existing mechanical artificial limb is avoided, and even a biological signal collection mode with a surgically-implanted electrode or a complex pattern recognition calculation control mode is omitted; the bionic artificial limb has the advantages of being easy and convenient to use, noninvasive, economical and practical.

Description

technical field [0001] The invention relates to the technical field of artificial limb control, in particular to a bionic artificial limb based on bioelectrical resistance measurement. Background technique [0002] Bionic prosthetics are an integral part of the lives of amputees, yet most of the prosthetics on the market today are purely mechanical. Although this kind of prosthesis is economical and affordable, its functions are simple, and it often cannot meet the needs of patients other than snatching. Although electronically controlled advanced prosthetics can perform more and more complex movements, they are expensive. Bioprosthetics under study that use complex pattern-recognition algorithms to interpret muscle biosignals (EMG) on muscle nerves to control robotic arms are more powerful but also more complex. And in order to achieve better control effect, it is often necessary to implant electrodes from the arm. [0003] Bioelectrical resistance measurement is a non-i...
