Problems solved by technology

In order to diagnose the indicators of the above chemical components, it is necessary to break the blood-brain barrier and directly extract the brain fluid, which brings a high risk of secondary infection; therefore, a non-invasive detection method outside the blood-brain barrier is needed, which is closest to the brain Body fluid is saliva. The saliva during the day cannot be used for accurate testing due to too much interference from the outside world. Only the saliva in broken dreams at night can reflect the activity of the brain, and one-time sampling cannot accurately report. Repeated sampling and testing are required to finally obtain accurate results. in conclusion

Abstract

The invention relates to the field of biomedical electronics, in particular to a microelectrode material, a preparation method of a microelectrode and a detection device applying the material. The microelectrode material is formed by mixing graphene, glassy carbon and amino acid. The detection device applying the microelectrode material is used for judging physiological and psychological conditions of a human body and comprises a sending end and a receiving end, wherein the sending end comprises a sensor, a scanner, a primary processor and a sender; the sensor, the scanner, the primary processor and the sender are sequentially connected; the receiving end comprises a receiver, a secondary processor and a data transmission interface; and the receiver and the secondary processor are sequentially connected. The microelectrode material, the method and the device have the benefits that the microelectrode is made of the microelectrode material; a current value obtained by cyclic voltage scanning is transmitted to the receiving end for analysis and processing; the biosensor noninvasively and automatically detects concentration of personal neurotransmitters and non-neurotransmitters, so that the physiological and psychological conditions of the human body are judged; and personal privacy is protected.

Description

technical field [0001] The invention relates to the field of biomedical electronics, in particular to a microelectrode material, a method for making the microelectrode, and a detection device using the material. Background technique [0002] Everything in the world is divided into cyclic interactions of yin and yang. All living organisms rely on the change of electric potential to convey the signs of life. When the electric potential stops changing, it is the moment when life ends, and human beings are no exception. When the female plant of marijuana receives the pollen from the male plant, the potential change of the flower bud is strengthened, and the fruit will become fatter, otherwise the fruit will be thinner, so as to ensure the best inheritance of life. As the saying goes, dogs can't change their nature of eating shit. In fact, dogs don't eat shit. They just use their saliva to shed their own marks to communicate with other dogs. He may be saying to her: "Honey, it lo...
