Technical field

The invention relates to the technical field of smart components, and in particular to a new type of smart wearable components with self-powered flexible electrodes.

Background technique

With the enhancement of people's health awareness, it is widely known that one to two physical examinations per year to control the physical condition. But in fact, many people who feel uncomfortable often find no problems in routine physical examination, that is, they are in a sub-health state-which does not meet the diagnostic criteria of the disease, but the organ function deteriorates and causes physical discomfort.

On January 20, 2015, US President Barack Obama proposed the "Precision Medicine Plan" in his State of the Union Address. This plan caused a surge in the medical and health industry market. Since then, China has also proposed its own precision medicine plan. It is expected that by 2030, my country will invest 60 billion yuan in the field of precision medicine.

The essence of precision medicine is through the analysis, identification, verification and application of biomarkers for large sample populations and specific disease types, so as to accurately find the cause of the disease and the target of treatment, and personalize the disease for specific diseases and specific patients. Treatment, thereby improving the cure rate of the disease.

Traditional medical testing instruments and smart wearable products measure human vital signs data mainly include heart rate, blood pressure, body temperature, respiration rate, etc., but these are far from meeting people's needs for health management, and can not establish sub-healthy human condition and disease A data model of the relationship between algorithms.

Existing hospital medical examination large-scale medical testing equipment is often fragmented measurement, and only after illness, will measure blood, urine, CT and ultrasound, is a fragmented disease examination, can not measure the comprehensive data of various organs of the whole body, nor Long-term follow-up monitoring cannot even prevent disease and improve in advance.

Existing smart wearable monitoring products are only used to measure heart rate, heart rate variability, blood pressure, blood sugar content, exercise fat content and other information. A comprehensive analysis is carried out in a unified manner. For example, some elderly people experience dizziness, chest tightness, and arm numbness. This may be due to cardiovascular and cerebrovascular diseases, or it may be caused by insufficient compression of the spine.

Precise preventive medicine treats people as a whole and a system. Most diseases are not an organ or a single physiological problem, but a complex network of multiple organs and systems that affect or contain each other, which involves genes, Environment, sports, vitality, mental state, etc., are comprehensive factors influencing life and health. The traditional clinical medicine is to treat diseases. When the body is uncomfortable or a certain test index reaches the standard prescribed by medicine, the doctor will say that someone has a certain disease according to a certain system or an organ, and then use drugs or surgery. Killing or removing for the purpose of controlling symptoms does not completely restore the severely damaged organs of the body to the original healthy state, and the fragmented diagnosis results cannot provide a comprehensive cause analysis.

The 21st century is an era of outbreaks of chronic diseases, nutritional diseases, and malignant diseases. Traditional medical models have been unable to meet our rising health needs. Diet and nutrition starting with precision medical monitoring are the key to regaining health. A correct diet and nutrition plan are inseparable from accurate physical condition analysis, digestion and absorption function analysis, nutritional metabolism function analysis, detoxification and detoxification ability analysis. In such a special era that just needs technology and health personalization, the smart wearable medical monitoring product of the present invention combines precise nutrition and functional medicine to become an indispensable health instruction for everyone.

The smart wearable components and extended products involved in the present invention, through the combination of bioelectronic informatics and wearable hardware, integrate the knowledge base of Western functional medicine and traditional Chinese medicine to treat unhealthy, and use wearable hardware to collect human micro-current, weak magnetic field and other information The data is compared with the health data model of normal people. After long-term continuous measurement of human vital signs data, the sub-health status of the human body is analyzed based on deep learning and algorithm models, and the causes and causes of chronic diseases and cancer accumulated in the later period are deduced. The disease process.

Precision medicine in the new century is a dynamic method for assessing, preventing, and treating complex chronic diseases. The advanced intelligent wearable monitoring device or instrument of the present invention can be used to quantitatively monitor various cell states of human organ functions, based on the biochemistry that causes disease And metabolic disorder test results, provide doctors with reference data for the treatment of patients. By improving nutrition diet, lifestyle habits, comparing the effects of medication and treatment, after long-term follow-up observation and intervention treatment, prevention and reversal of the deepening of the disease, through Accurate data and algorithm models can achieve the effect of quantifiable analysis of traditional Chinese medicine treatment.

The present invention also has the following features:

1. Collection hardware detection chip is bioelectric EDA and bioelectrical impedance BIA chip, and the collected data is skin (surface) electrical activity EDA/skin electrical response GSR (excitation signal from DC to 200 Hz), and bioimpedance analysis BIA (50kHz Excitation signal) Among them, FIG. 5 shows a schematic diagram of bioelectric EDA acquisition on the smart wearable component, and FIG. 6 shows a schematic diagram of the working principle of the bioelectrical impedance analysis BIA of the smart wearable component.

2. The flexible electrode 20 uses flexible nanomaterials, including: a graphene base plate 21, an organic electrochemical transistor 22, a flexible organic photovoltaic cell 23 (organic photovoltaic solar cell, OPV battery), and a circuit 24. Among them, the flexible nano-materials can be used to collect body skin electrical and electromagnetic fields, and are comfortable and breathable, prevent sweat erosion, and can be washed multiple times. The electrode circuit and the fiber of the clothing are fused together, a polymer material with excellent conductivity and stretchability, which can be used for stretchable plastic electrodes. This flexible electrode can also be used as a wearable electronic device, with "smart" clothes or power supply equipment in the body will no longer be constrained by stiff circuits. Flexible electrodes are electronic technologies that make electronic devices on flexible or ductile plastic or thin metal substrates. Existing electronic devices, including electrodes and materials, are hard and are good for wearing on a wearable device, but if they are When applied to the measurement of central nerve current and heart current, implantation in the brain or heart may damage nerves or heart tissue. Therefore, electrodes in contact with nerves need to be as soft as skin, which is an important problem to be solved for flexible electronic applications.

The graphene base plate 21 is a thin flexible polymer and has a light transmittance of 96%, which is almost a transparent material, and it also has high conductivity, so it is very suitable to apply it to the flexible electrode substrate. In order to increase the toughness and mechanical properties of this material, special additives are added to change the structure between the molecules of the material, making the polymer material easier to stretch. After testing, the new material can still maintain high conductivity when it is stretched to twice its original length.

The introduction of zinc oxide structure combines the solar cell (OPV) and the electronic devices of organic electrochemical transistors 22 (OECTs) on an ultra-thin substrate made of parylene plastic plus graphene material, as shown in the figure? The schematic diagram of the flexible electrode shown, wherein the organic electrochemical transistor 22 includes a source 221, a drain 222, a gate 225, a ground 224, and an insulating layer 223 between the gate and ground. The channel between the source electrode 221 and the drain electrode 222 is filled with graphene.

By introducing the zinc oxide structure into the OPV battery, the solar cell (OPV) and the electronic devices of organic electrochemical transistors (OECTs) are combined on an ultra-thin substrate made of parylene plastic and graphene material. OPV battery can convert 10.5% of the received light energy into electrical energy, which is the super flexible element with the highest power conversion efficiency. These structures consist of nanoscale patterns that promote electron transport in OPV cells and maximize energy conversion efficiency.

Another key advantage of OPV cells over rigid solar cells is that the power conversion efficiency is not sensitive to the angle at which the cells are illuminated. In a conventional solar cell, light incident on the cell surface at a larger angle will experience more reflection, resulting in lower efficiency. But in this device, nanoparticles can minimize the reflection of incident light, regardless of the angle of illumination. As a result, the efficiency of these devices is not affected by motion, which is an ideal characteristic of wearable biosensors. The use of a flexible OPV battery to power a flexible sensor requires the former to have stable electrical performance under mechanical deformation. Traditional flexible OPV batteries do not meet this requirement because they are made of thick and hard materials, which makes the device fragile. This device takes advantage of the ultra-thin nature of its nano-patterned OPV battery, and laminates the device on a pre-stretched elastomer (rubber analog). The resulting device can not only be placed on a curved surface, but also stretched To twice the initial length (mechanical strain is 200%), and still maintain high power conversion efficiency. Even after going through 900 stretching and release cycles, the efficiency drops to only about 75% of its initial value.

OECT can work with low voltage (about 1 volt), which is also within the power supply capacity of OPV batteries. The nanoparticle OPV battery is used to drive OECT, which is composed of a sensitive and flexible biosensor. Scientists have proved that the self-powered OPV-OECT sensor platform can detect biological signals (pictured). They connected the platform to a person's finger and a gel electrode to the person's chest. Due to the movement of ions in the human body, each bioelectrical signal generates a voltage difference between the electrode and the platform. This difference is usually too small to be detected, but since OECT can achieve high signal amplification, it can be measured here. Under the constant illumination of light-emitting diodes, the platform recorded clear bioelectric and electromagnetic wave signals. The recording sensitivity is about three times that of OECT powered by conventional power. This is because no external power connection reduces signal fluctuations.

Before the OPV system can be fully integrated into a wearable device, several optimizations are required. The transmission of electronic signals from the platform is still based on traditional rigid silicon-based electronic devices powered by external sources. The OPV system of this device is a milestone in the production of ultra-thin and efficient solar cells for self-powered applications. In addition, the device is designed to develop retractable, stretchable, and even healthy self-powered biosensors for accurate, sensitive, and continuous measurement of biological signals.

Adding graphene material to the base plate can better store the energy of light conversion, and achieve a longer standby time, which is convenient for long-term monitoring and data comparison.

3. The biochip capacitive sensor 70 and the microcontroller are composed of different amplifiers and transducers to achieve different biological signal acquisition and analysis functions.

Selection of different amplifiers:

1) DA Universal Amplifier: This low noise differential bridge amplifier connects different transducers to the micro control system. It provides gain setting and offset adjustment, reference baseline adjustment and power supply for some transducers. The amplifier is used to record signals of active and passive transducers such as bioelectromagnetic waves and bioresistance through transducers.

2) EBI bioimpedance amplifier: measures parameters related to cardiac output and changes in chest impedance due to respiration. The precise high-frequency current source of the EBI bioimpedance amplifier injects a small current of 100 μA into the body tissue enclosed by the attached electrode, and then a set of independent monitoring electrodes measures the voltage on both sides of the tissue. Because the current is fixed, the measured voltage is proportional to the impedance of the tissue. The EBI bioimpedance amplifier simultaneously measures the amplitude and phase of this bioimpedance and records the impedance at four frequencies from 125KHz to 100KHz. When in use, the EBI bioimpedance amplifier is connected to four unshielded flexible electrode leads, hidden in the smart wearable clothing.

3) GSR skin response amplifier: measure the skin conduction strength and response, when tension, arousal or emotional agitation, they show different changes with sweat gland activity. A constant pressure technique is used to measure skin conduction. Control allows selection of absolute or relative skin conduction measurements. Each skin response amplifier requires a charged epidermal response transducer. For unconventional body placement, use self-powered flexible bioelectrodes on the skin reaction amplifier, and do not apply electrode paste.

4) EMG myoelectric amplifier: used to amplify conventional and bone myoelectric activity. It can be used to monitor the electrical activity of individual fibers, motor sites, and peripheral nerves because it can respond quickly and be timed. The software can be used to perform real-time EMG measurement. It can match all 2mm flexible electrode plugs, including shielded electrode plugs for highly sensitive measurement.

5) MCE microelectrode amplifier: It is a low noise differential amplifier with extremely high input impedance, which is used to accurately amplify the electrical signal obtained by the microelectrode. It is used to record skin, muscle, nerve activity and cell potential, and can choose input capacitance compensation and current clamp. The cable shield of the input signal can be made to follow the voltage (reduce the input capacitance) or simply ground (reduce the noise feedback). The microelectrode amplifier includes manual control input capacitance compensation (+/-100pF) and clamp current zero adjustment. In addition, the external voltage control of the microelectrode amplifier can change the clamping current (100mV/nA) proportionally. The D/A output of the microcontroller when recording bioelectric signals can generate this external control voltage that changes the clamping current. The microelectrode amplifier also includes a clamping current output monitoring port so that the microcontroller uses another input channel to monitor the clamping current. Normally, when input capacitance compensation and current clamp recording are not used, standard shielded or unshielded electrode lead wires can be used.

Transducer selection of different biosensing signals:

1) Temperature measurement probe for smart wear: (impedance: 2252 Euro; maximum temperature: 60℃)

Body surface temperature probe, attached to the skin surface to measure the temperature. Response time is 1.1 seconds. The diameter is 9.8 mm. The thickness is 3.3 mm.

2) Skin resistance sensor: connected with GSR skin response amplifier to measure skin conductivity.

Two 6mm diameter Ag-AgCl non-polarized electrodes are fixed on the finger, and the shielded wire is 3 meters long.

3) Bioelectric electrode: The silver chloride silver electrode is used repeatedly. Shielded bioelectrical electrode, unshielded bioelectrical electrode, mesoporous bioelectrical electrode, X-ray transparent bioelectrical electrode (reference size: 7.2 mm outer diameter, 4 mm electrode diameter, 6 mm thick. Lead wire 1.5 m long .)

4) LEAD electrode lead wire: used to connect flexible patch electrodes to record bioelectrical signals.

The flexible electrode nanomaterial of the intelligent wearable monitoring component of the present invention relates to a tactile information processing technology that imitates nerve sensory feedback in the field of biological nerve conduction. Synapse electronics has shown strong development momentum as an emerging field in bionic neuromorphic computing. Synaptic plasticity is the basis for performing distributed calculations on perceptual signals, and preliminary processing is performed during signal transmission based on weights. Synapses are the physical nodes through which biological signals are transmitted in nerve fibers, with bidirectional plasticity. Its weight can not only be increased to represent a reinforcement learning behavior, but also suppressed to maintain the overall low power consumption characteristics of the nervous system. The artificial synapse based on the simulation of intelligent piezoelectric transistors is helpful to build the neuromorphic interface of robot sensing and realize deep learning. It has the necessary conditions to simulate the plastic function of the peak timing of the nervous system, and it is also realized by the pulse neural algorithm The potential of artificial intelligence unsupervised learning, motion capture and pattern recognition.

Multi-perception feedback can establish a dynamic spatiotemporal logic relationship between neural networks. This is a unique neuromorphic computing feature that senses synapses differently from classic sensors. As the basic performance of spatial resolution, the device has different responses to the input of different signal sources. For different sequences of stimulation pulses, the response of the device is also different, in order to achieve the basis of time resolution. At the same time, this artificial synapse also shows the logical relationship corresponding to compressive strain and tensile strain, respectively, which is the basic unit of building a more complex and versatile large-scale artificial neural network in the future to realize a parallel perceptual computing system. This work may pave the way for self-driving artificial intelligence and neural robots.
