Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] In the field of nerve signal recording, the use of metal wires to transmit signals is prone to infection and cannot record the nerve signals of animals or humans under non-anesthesia for a long time. The data transmission rate of the radio frequency transmission method is low, the power consumption is large, and it is easy to be interfered. The invention not only solves the problems encountered in the metal wire transmission mode, but also solves the difficult problems encountered in the radio frequency transmission mode.

[0029] The present invention utilizes the characteristics of the human body as a conductor and electrolyte, uses the human body itself as a signal transmission medium, and records the microelect...

Abstract

The invention discloses a high-speed low-power consumption signal transmission method applied to implanted record. In an implanted record microsystem, a record microelectrode, a record pretreatment circuit and a transmitter are integrated together and implanted into a human body. The record microelectrode extracts s which are transferred to the human body by the transmitter through the microelectrode after processed by the pretreatment circuit, and the human body is used as a signal transmission medium to transfer s outside the human body in a body channel transmission way. In the external world, the microelectrode is used for detecting signals, and the signals are transferred to external equipment through a receiver. The invention can realize high transmission rate and low power consumption for signal transmission.

Description

technical field [0001] The invention relates to the technical field of human nerve signals, in particular to a high-speed and low-power signal transmission method applied to implantable nerve signal recording. Background technique [0002] Real-time recording of human neuron activity is of great significance for both scientific research and clinical medicine. At present, many kinds of nerve signal recording microelectrodes have been designed in academia. These electrodes are implanted into the body to extract nerve signals. The extracted nerve signals are directly connected to external devices through metal wires to realize signal transmission. In medical applications, the transmission method that directly connects electrodes implanted in the body to external devices through metal wires is prone to infection. In addition, this method generally anesthetizes the subject, so it is difficult to record the neural signals of a freely moving person in a non-anesthetized state, and...
