Shape memory alloy bionic joint based on brain wave control

Abstract

The invention discloses a shape memory alloy bionic joint based on brain wave control. The joint comprises a brain wave acquisition module used for information collection and a Bluetooth communicationcircuit used for information transmission, also comprises a single-chip control system used for information processing and display, and finally comprises a bionic finger joint used for an entity. Thebrain wave acquisition module, the Bluetooth communication circuit, the single-chip control system and the bionic finger joint are electrically connected in sequence. The brain wave acquisition module is composed of ear clips, a radio wave acquisition chip and forehead electrodes. The brain wave signal is acquired and analyzed to control shape memory alloy wires driven to drive the bionic fingerjoint to move. The method solves the problem that traditional bionic joints are not easy to achieve miniaturization and low in work efficiency and flexibility, and provides a practicable design schemefor the humanized application of the bionic joint in the medical field.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a shape memory alloy bionic joint based on brain wave control. Background technique [0002] Traditional actuators basically use motor drive, hydraulic drive, and pneumatic drive. The drive device has a complex structure, large volume, and high cost, and it is not easy to realize the miniaturization of the drive. The shape memory effect of the shape memory alloy returning to its original shape by heating is used to generate recovery displacement and recovery force. , using shape memory alloy as a driver to solve the shortcomings of traditional driving methods. With the in-depth and extensive research on brain wave technology by more and more scholars, brain wave technology is gradually applied to actual products. Conventional brain wave application control signals are generally divided into two categories: focus signal and relaxation signal. The degree of conc...
