Wearable myoelectricity instrument

Abstract

The invention provides a wearable myoelectricity instrument which comprises one or multiple electrodes, an amplifying circuit, a filter circuit, an A / D (analog to digital) converter, a digital signal processing unit, a wireless communication interface, a storage unit and a battery module. The electrodes are in contact with the surface of a human body; the amplifying circuit is used for amplifying myoelectric signals collected through the electrodes; the filter circuit is used for filtering out noise waves of the human body; the A / D converter is used for converting the myoelectric signals into myoelectric digital signals; the digital signal processing unit is used for converting the myoelectric digital signals outputted through the A / D converter into the signals capable of being recognized through a terminal instrument or control commands capable of being processed; the wireless communication interface is used for transmitting the control commands wirelessly to the terminal instrument; the storage unit is connected with a microprocessor; the battery module is used for powering the instrument. Through combination of the myoelectric signals with the wireless communication technology, the terminal instrument can be controlled under the conditions that conventional instruments like a mouse are not available; corresponding relation of muscle motions and the control commands can be matched in a customizable manner by users, and personalized use habits of multiple users can be dynamically adapted.

Description

technical field [0001] The invention relates to a myoelectric device, in particular to a wearable myoelectric device. Background technique [0002] With the development of wireless technology, devices such as wireless mouse, wireless keyboard, and Bluetooth headset have freed users from the shackles of wired devices. Compared with wired devices, wireless devices have brought convenience to users, and at the same time make their relative positions with terminal devices It is much more flexible; in the existing market that pays more and more attention to user experience, it is necessary to provide a detachable device that only uses human body movements to control the terminal device, and it is also very promising in the market. It can bring users The convenience is no less than wireless instead of wired. [0003] Myoelectricity refers to the potential changes that occur due to the generation, conduction and spread of muscle fiber action potentials when skeletal muscles are ex...
