[Prior Art] The gas exhaled by the human body reflects the condition of various organs and tissues in the human body. For example, inflammation and oxidative stress can be monitored by measuring the change in concentration of the following gases: nitric oxide (NO) Exhaled carbon monoxide (C0) is also a marker of cardiovascular disease (cardi〇Vascular diseases), diabetes (diabetes), nephritis, and bilirubin production; exhaled low molecular mass carbon argon compounds, for example Ethane and n-pentane; ethylene and isoprene, c5H8 (ethylene 'and isoprene), isoprene is derived from the process of cholesterol synthesis in human body, and its concentration is related to food' Through exhalation, it can be used as a special marker for blood cholesterol concentration.

Med. 1319978 27 1182-92] The smell of gas is due to infection and Disordered, providing a path for chemical sensors for biochemical applications. Nitrogen dioxide (N02) is associated with bronchial epithelial infection and is caused by smoking. Ammonia is the product of urea decomposition. [studei· s M, Orens JB, Rosas I, Krishman JA, Cope KA, Yang S, Conte JV, Becker PB and Risby TH 2001 Patterns and significance of exhaled-breath biomarkers in lung transplant recipients with acute allograft rejection J. Heart Lung Transplant. 20 1158-66]. For this reason, a sensor that can effectively and continuously monitor the exhaled gas of the human body is of great importance. In addition, many infectious diseases or allergies come from the external bio-gas gel, if it is itself. For the original person, the corresponding biogas gel will be exhaled into the outside air through the nose and mouth, so the present invention proposes a gas and gas gel device capable of sensing human breathing, especially a kind of hanging on the nose. The carbon nanotube is a gas and gas shift sensing component, combined with a signal processing circuit and a wireless transmission/reception module, for measuring, alerting, transmitting and receiving physiological signals, and of course, by means of a mask-like manner. To measure the gas and gas in and out of the mouth, just change the way of packaging. SUMMARY OF THE INVENTION The present invention provides a human respiratory gas apparatus, including exhaled and inhaled gas species, concentration, and temperature, which are mainly nanocarbon tubes, alkali materials, and purified carbon nanotubes. Or the surface-modified carbon nanotubes react with specific gases to produce electrical changes, such as resistance, capacitance, mass, and transistor characteristics. For foreign harmful gases, it is difficult to respond to high-sensitivity and response through carbon nanotubes. Fast speed, when _ to harmful substances, can immediately remind the user to avoid immediately, to avoid the harmful gas, such as - carbon oxide, a fever, etc.; more can be side of the human body exhaled gas type, Han (four) turn, Temperature, and humidity are used as a reference or diagnosis for monitoring physiological conditions. If the Qibu County carbon tube is used for the job or the antibody or aptamer (aptamei^_(carbohyd her) attachment modification, it can be inhaled externally or 1319978 • the gas gel exhaled in the body, such as influenza virus, tuberculosis, etc. The apparatus for sensing the human body breathing gas and the gas gel can achieve at least the substrate, the carbon nanotube element, the signal processing circuit, the wireless transmitting/receiving module or a near The network (b〇dy-network) transmitting/receiving module and a power supply; the user can arrange the body breathing gas and the gas glue device on the body, and continuously measure the gas and gas of the user's breathing. Glue, after reacting with a gas or a gas gel through a carbon nanotube sensing element, 'using a signal processing circuit to perform electrical measurement of the carbon nanotube sensing element, and using the wireless measuring signal by wireless transmitting/receiving mode a group or a close-in network transmission/reception module, transmitted to a remote monitoring device or another warning device for monitoring or recording by the time or monitoring personnel, if the use of f inhaled or exhaled harmful gas or gas glue, Exhaled gas temperature is too high to trigger firing If the water content of the gas is too much for the gas, the ship user or the remote monitoring person can immediately get the warning. 'The nano-components are widely discussed and studied, mainly for the purpose of nano-sensing. The component has a high sensitivity and low power consumption of the lion, especially in the medical examination _ domain towel, such as the scale is less than the sub-micron (SUb-micrometer) to the nanometer scale, virus or employment, etc. The size of the object to be tested is much smaller than micro The size of the machine's inductance measuring component makes the sensing component fabricated on the micrometer scale in the sensing accuracy and speed. The invention cannot satisfy the actual demand. The invention will be used as a nano sensing component. (nan〇sens〇r) to detect the side of human harmful substances and human health status 'to achieve sensitive, energy-saving, repeatable measurement and low cost of manufacturing, this sensing unit can be mass-produced at the same time · The measurement and the human body's health condition are long, and if it is used by many people, it can also be combined with each other to become a wireless system (10), forming a __ view of the big anti-蒦 network without dead ends, and 疋 action type. Especially in the case of epidemic diseases, Such as bird flu, mouth Foot-and-mouth disease, mad cow disease, SARS # epidemic stage, can be implanted in some poultry, piglets, cattle and people suspected of SARS, if they can be added to the wireless sensor network, so - come The breadth and density of protection will be more comprehensive. *In the past 4 years, research on electronic components based on carbon nanotubes has been continuously carried out by many research institutions. ^^ shows that carbon nanotubes are in The length of the channel is short, 1319978, for example, less than one micron, 'has the characteristics of Ballistic Transportation, and the current capability of a single carbon nanotube channel can withstand (~25βΑ). These excellent transistor characteristics are likely to replace the existing ones. The CMOS chip becomes the next generation of electronic components. In addition, the carbon nanotube electronic components can also be used to detect foreign molecules (gas molecules, biomolecules, etc.) in the environment when the channel length is long, which not only has high sensitivity detection capability, but also The detector's size and power consumption are greatly reduced, and it can be used as a sensing element for various highly sensitive and specific detections through surface modification of specific carbon nanotubes. As can be seen from the above description, electronic components based on carbon nanotubes will be able to become potential transistors and sensing elements in the future. According to Kong et al. in 2000 [JK ong, NRFranklin, C. Zhou, M_G. Chapline, S. Peng, K. Cho, and H. Dai, Science 287, 622 (2000)] When the tube is exposed to gas molecules, such as N〇2, NH3, 〇2, etc., its resistance will change, and its response speed is about 1〇 times that of conventional solid-state sensors. Semiconductor 'type single-walled nanocarbon Its sensitivity to gases at room temperature will be as high as 1 〇 3 or more. Due to the high sensitivity of the carbon nanotubes, the sensing results are not to be affected by the environment, such as temperature and humidity. There are also many studies to propose solutions, such as Ashish M〇di et al. in 2002. [Ashish Modi, Nikhil Koratkar, Eric Lass, Bingqing Wei& Pulickel M. Ajayan, Miniaturized gas ionization sensors using carbon • nanotubes”' letters t0 nature, VOL 424, 10 JULY 2003】Using carbon nanotubes as gas ion sensors due to Different gases have different breakdown voltages (Breakd〇wn Voltage) and currents can determine the gas type and concentration, respectively, and are not affected by the environment. They use aluminum cathode and chemical vapor phase on yttrium oxide (Si〇2) substrate. Deposition (CVD) growth of vertical multi-walled carbon nanotubes as anode (radius 25~30nm, length 3 间距 coffee and spacing 5〇nm) to detect different gases in the air, the results of the study show that the sensor has a pole Gas selectivity and sensitivity. In addition, ES Snow et al., 2005 [ES Snow, F. K. Perkins, EJ Houser, SCBadescu, and TL Reinecke, Science 307, 1942 (2005)] The capacitance value of single-walled carbon nanotubes is measured as a gas sensing mechanism with high sensitivity and a large concentration measurement range; M.

Chen, 814 1〇61?61411, you /70/<? ratio 5,1774 (2〇〇5)] in 2005 When the carbon nanotube field effect transistor is used as a sensing element, it is found that it can be used to sense different gases, and its response speed and response time are extremely fast. 'Using exposure to different gases will generate different sensing currents, and this sensing The component has self-recovery sensing capability and has a fairly good sensing capability after repeated 50 sensing cycles. At present, there are quite a lot of researches on the use of carbon nanotubes as sensing elements. At present, gases that have been confirmed to be detectable by carbon nanotubes include book 3, C〇2, 〇2, brain, CH4, H2, N2, Ar, CO, NO, He, SFe, Methanol, Ethanol, Organophosphorus pesticides, and the like. "Nano Carbon Tube Gas Sensing Principle" 1319978 The theoretical model of gas sensing has been studied for many years, mainly based on the model of agglomerated semiconductor spheres, and - the current in the concealment is calculated by the heat radiation and the wear of the carrier. The surface electron density represents the state of being absorbed by the body and the state of the depletion layer is based on the calculation of the (four) transition surface, and the surface shape of the semiconductor band is considered! I 〇 sensitivity _ surface density conductivity logarithm derived. Gas sensing is mainly caused by the chemical effect of electrons, which leads to changes in the electrical properties of electrons at different locations. The most commonly used model is the qualitative analysis of the intensity of the particles, which involves the adsorption of electrons in the gas and solids. The conversion relationship (donor or acceptor) ^ - the commonly used metal oxide sensing H in 'because of the presence of oxygen or reducing the background gas in the environment, etc., will produce very obvious changes in electron conductivity" This is not only a single change in the concentration of the conduction electrons. It should also consider the change in the energy barrier formed at the interface due to the donor or acceptor of the adsorbate, controlling the flow of electrons between the interfaces. When the N-type semiconductor oxide is exposed to a reducing gas at a high temperature, the adsorbed oxygen is gradually consumed by the reaction with the reducing gas. The reduction of oxygen ions on the surface of the semiconductor oxide causes the electrons trapped by oxygen to return to the crystal grains, and this process leads to a decrease in the height of the energy barrier, that is, a decrease in electrical resistance. When the gas to be tested is in contact with the semiconductor, the energy level changes, and the electron moves from the high Fermi level region (the region near the semiconductor surface) to the low Fermi level region (the separation of the surface state charge causes the double layer voltage to form, Increasing the energy of the surface. When the double-layer voltage is large enough to make the Fermi level of the entire system Φ a constant, it is in equilibrium. The movement of the band near the surface is called bandbending. This phenomenon is used to indicate that the gas is adsorbed on the surface of the crystal grain and causes a change in the surface state, which causes a change in the characteristics of the carbon nanotube, including changes in inductance, conductance (or resistance), dielectric constant, and weight.

However, current methods have limitations, so it is quite difficult to achieve this goal. . Although nitric oxide (NO) has been identified as early as 200 years ago, the true recognition of its physiological importance was in the early 1980s. Numerous studies have established that NO is a major message molecule in the in vivo system. In addition, studies have shown that changes in exhaled NO have a significant correlation with other markers of respiratory tract inflammation. Since the technique for measuring NO in exhaled gases is non-invasive, reproducible, sensitive, and easy to perform, it is possible to use the monitoring of changes in exhaled NO to assist in the management of asthma (asthma) and other lung conditions (Ref. Literature: Choi J, Hoffman LA, Rodway GW, Sethi JM. Markers of lung disease in exhaled breath: nitric oxide. Biological Research for Nursing 2006 Apr;7(4):241-55.) Carbon nanotubes first placed in H2 〇2 reflux (reflux) with a mixture of sulfuric acid and nitric acid (3: 1) to remove carbon nanoparticles and produce functional carbon nanotubes, as a place to cover the tin dioxide 'then this acid treated The carbon nanotubes were stirred in a solution of 80 mL, 0.1 mol/L tin (II) φ chloride with 1.4 mL of hydrochloric acid, and stirred for 30 minutes with ultrasonic vibration. The product was filtered and rinsed with distilled water. In this way, the tin oxide nanoparticles are evenly coated on the carbon nanotubes and have a size of about 2-6 nm. The surface-modified carbon nanotubes are then connected to the electrodes by DEP to complete the impedance- or transistor-type or various sensing modes of the present invention. The principle of operation: when the sensor is in the air, oxygen molecules are absorbed onto the tin oxide grains, and the electrons are extracted from the tin oxide grains to become oxygen ions, so that the tin oxide grains are positively charged, and the barriers are Formed between tin oxide grains. Since the tin oxide nanocrystals are very small, there are many voids for gas absorption and reaction. When the sensor is placed in the NOx gas, the oxidizing gas molecules are further adsorbed to the tin oxide nanocrystals 'and extract electrons to form a higher barrier, because 19 1319978 when the sensor is placed in the air again ,]^0χ, the electron is also released back, so the sensor of this impedance type sensor will increase its resistance, and the molecules are released from the tin oxide nanocrystals and the resistance returns to the original value in the air. . [Example 2] Detection of Biogas Glue Particle modification was performed to detect bioparticles in the Chennai body and to understand the electrical changes of the prepared bioparticles attached to the surface of the carbon tube. /Λ^Characteristics are as shown in the round jade 'Fig. t, bare CNT represents the unmodified nanocarbon tube transistor finely viscous ΝΤ The surface of the transistor is not modified by PEI/PEG on the surface of the carbon tube, from the figure It can be seen that the IV characteristic curve of the electric male body decorated by the antibody t has a tendency to shift to the left, and the gate of the electric gate is planted.

Figure 5. Sal. represents Salmonella and carbon. The characteristics of the transistor iv after the surface of the tube is bonded - it can be seen that the current is significantly decreased before the junction with the Salmonella, and the gate threshold voltage Vg can be rotated to about IV. When the acid is combined with the antibody on the surface of the carbon tube, the carbon tube diameter is distorted, so the mobility of the surface charge of the carbon tube is lowered, and the ι-v characteristic curve is also decreased. When the source source is drained with a 5V bias voltage Vds and a 5V gate voltage is fixed, the current change is shown in Figure 6 for the transistor immediate current signal. When the VDS bias of 5V and the gate bias of -5V are applied to the carbon nanotube transistor, the transistor maintains a current of 8 X i〇_8a. When the PBS buffer solution drops between the two electrodes, it will be because The surface tension type is coated with a water droplet on the carbon nanotube.

Therefore, the experiment of this current signal found that when Salmonella binds to the antibody
