Technical Field

the invention relates to a head-mounted device for monitoring human health information based on a pressure sensing array.

Background

With the vigorous development of wearable technology industry, various products are developed endlessly. According to statistics, the commodity quantity of the wearable equipment in the world in 2018 reaches 1.72 hundred million. People's consciousness and demand to using wearable equipment to gather self health data constantly promote, and the mainstream product still is motion bracelet watch class at present. The flexible off-electron sensor developed by the titanium deep technology has the advantages of high sensitivity, high signal-to-noise ratio, low power consumption, quick response, high integration, simple structure and the like, and can detect weak pressure change. The verification proves that the sensor can well detect the pulse wave of the main artery of the human body through the body surface, and the resolution ratio of the pulse wave which can be detected is higher. Therefore, the flexible off-line electronic sensor is adopted to measure and analyze the pulse wave of the head artery, and the intelligent wearable solution is an innovative intelligent wearable solution and has great market value.

the pulse is a periodic, regular pulse of blood pressure in the artery followed by the heart beat. The characteristics of the pulse wave can be detected to obtain a great deal of information which can reflect whether the cardiovascular function of the human body is abnormal or not, and a convenient and reliable monitoring method is provided for people, particularly patients with chronic cardiovascular diseases. The physiological and pathological information of human body extracted from pulse wave is regarded as the basis of clinical diagnosis and treatment, and has been paid attention by the medical field. The comprehensive information of the pulse wave in the aspects of form, strength, speed, rhythm and the like reflects the blood flow characteristics of a plurality of physiological pathologies in the cardiovascular system of the human body to a great extent, so that the pulse wave acquisition and processing method has high medical value and application prospect. The artery of the head, such as the superficial temporal artery near the temple, can be touched to beat by hand under normal conditions, and is close to the positions of the large aorta and the heart, so that the pulse wave at the positions can be measured, and the physiological parameters can be obtained in real time, and the method has great value.

The heart is excited by the pacemaker, the atrium, and the ventricle in succession in each cardiac cycle, and numerous myocardial cells conduct and reflect the sum of action potential changes to the body surface along with bioelectricity changes. There are potential differences between multiple points on the body surface, and these bioelectrical changes are called electrocardiograms. Electrocardio is collected and recorded by an instrument, and the form is widely used for evaluating and diagnosing cardiovascular functions in medicine.

but no wearable product using electrocardiographic technology for the head is available in the market at present. The reason is as follows: the acquisition of electrocardio is limited by position and needs to be carried out through multiple points on the body surface. Therefore, the electrocardiosignal acquisition through the head is low in convenience. In addition, the existing research shows that the electrocardiosignal of the head is very weak, which brings trouble to the measurement. Moreover, the electrocardiosignal is seriously interfered by electromagnetic, and is not suitable for a wearable scheme for health collection on the head. Finally, the area occupied by the electrocardio-circuit and the electrode is large, and the portable integration scheme is limited.

The photoelectric pulse volume wave technology is a non-invasive detection method for detecting the change of blood volume in living tissue by means of photoelectric means. When a light beam with a certain wavelength irradiates the surface of the skin, the light beam is transmitted to the photoelectric receiver in a transmission or reflection mode, and the light intensity detected by the detector is weakened in the process due to the absorption attenuation action of skin muscles and blood at the detection end, wherein the absorption of the skin muscles, tissues and the like to the light is kept constant in the whole blood circulation, the volume of the blood in the skin is changed in a pulsating mode under the action of the heart, the peripheral blood volume is the largest when the heart contracts, and the maximum detected light intensity is the smallest; when the heart is in diastole, on the contrary, the detected light intensity is the maximum, so the light intensity received by the light receiver is in pulsatile change, and the change signal of the light intensity is converted into an electric signal, so the change of the volume pulse blood flow can be obtained. It can be seen that the volume pulse blood flow includes many important physiological information of the cardiovascular system such as blood flow. Meanwhile, the volume pulse blood flow mainly exists in micro-arteries, capillaries and other micro-vessels in peripheral blood vessels, so the volume pulse blood flow also contains abundant micro-circulation physiological and pathological information, and is an important information source for researching human body circulation systems.

But there are products currently on the market that use photoplethysmographic technology for head wearables. Such products place a photoelectric sensor at the forehead for monitoring the heart rate of the user. However, such products still suffer from a number of disadvantages: because the photoelectric sensor is made of hard materials and must be in direct contact with the skin, the photoelectric sensor can generate uncomfortable feeling after being worn for a long time; in addition, the technology is greatly influenced by external environment light, and higher accuracy cannot be achieved; in the application scenario of the head, skin sweating can also cause a large interference to the photosensor reading.

Neither of these two techniques can represent static pressure when the headgear is worn.

Based on the above problems, there is a need to provide a head-mounted device for monitoring human health information based on a pressure sensing array, which can solve the problems.
