[0016] As described in the background technology, the existing pulse diagnosis device can only dynamically collect one physical characteristic. From the physiological characteristics, human fingers can not only sense the pressure distribution of the skin on them, but also can feel the physical characteristics such as temperature, humidity, vibration, and fluctuation, thus forming a more comprehensive perception, cognition, and judgment of the pulse in the mind. Therefore, the electronic pulse diagnosis device more realistically simulates, or even replaces human fingers to fully and accurately sense and reproduce the biophysical characteristics of the pulse. The core is that the array sensor imager must have the function of synchronously sensing pressure and one or more other physical characteristics in situ in each pixel unit.

[0017] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

In addition, the terms "first, second, third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first, second, third" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In the present invention, it is an electrical device, so connection and interconnection both refer to conductive interconnection. Since the accompanying drawings are descriptions of the same device, the same numbers in the drawings represent the same components.

[0019] The present invention provides an electronic pulse diagnosis device, which comprises: at least one composite function sensor array group, the sensor array group consists of a pressure sensing unit array and a temperature sensor array; a pressure adjustment device for applying pressure to a human wrist; and a fixing device for fixing the sensor array group and the pressure adjustment device on the human wrist.

[0020] The electronic pulse diagnostic device provided by the present invention uses three independently controlled electronic fingers, each of which includes a composite functional sensor array group, which has the function of simultaneously collecting physical characteristic signals of pressure and temperature, and even humidity and vibration, so as to more comprehensively collect the biological characteristics of human pulse.

[0021] The specific examples of the present invention are further described in detail below with reference to the accompanying drawings. Figure 1 As shown, the pulse diagnosis device provided by the present invention comprises:

[0022] At least one composite function sensor array group 210, the sensor array group is composed of a pressure sensing unit array 211A and a temperature sensor array 211B; a pressure adjustment device 219, used to apply pressure to the human wrist 10; a fixing device 110, used to fix the composite function sensor array group 210 and the pressure adjustment device 219 on the human wrist 10. The pressure adjustment device 219-temperature sensor array 211B-pressure sensing unit array 211A are stacked from the top layer to the side close to the human skin, and the pressure adjustment device 219 is located on the side close to the human body. The temperature sensor array 211B includes infrared temperature sensors 212 arranged in an array. In this embodiment, three pressure adjustment devices 219 are included, corresponding to three electronic fingers respectively, and the temperature sensor array 211B and the pressure sensing unit array 211A are stacked, that is, each pressure adjustment device 219-temperature sensor array 211B-pressure sensing unit 211A stacked structure corresponds to one electronic finger, and a total of three such stacked structures are provided. The pressure sensor unit array 211A is composed of pressure sensor units arranged in an array, and the temperature sensor array 211B is composed of temperature sensor units arranged in an array.

[0023] In this embodiment, the composite function sensor array group 210 also includes a peripheral readout circuit 220, which is specifically arranged above the temperature sensor array 211B. In another embodiment, the peripheral readout circuit can also be arranged on the test surface or above the pressure adjustment device 219, so that it is not affected by the pressure adjustment device.

[0024] In another embodiment, optionally, the composite function sensor array group 210 further includes at least one of a humidity sensor array or a vibration sensor array, which can be stacked with the pressure sensing unit array 211A and the temperature sensor array 211B, and the position is not limited. Optionally, the composite function sensor array group 210 further includes a light irradiation unit or a light detection unit, which can be stacked with the pressure sensing unit array 211A and the temperature sensor array 211B, and the position is not limited.

[0025] Figure 2 The structure of the sensor group in the composite functional sensor array group 210 is described below. The sensors in each layer of the composite functional sensor array group 210 correspond to each other, and one sensor is taken from each layer of the array to form a sensor group. Figure 2 The following description is about the structure, position and connection relationship of each sensor in the sensor group. Figure 2 As shown, in this embodiment, the sensor group includes a cavity unit 211C and a cover unit 211D in contact with the skin 30. The cover unit 211D is made of high-resistance silicon. The pressure sensor unit is composed of a pressure-sensitive unit 211A1 and a pressure-sensitive electric unit 211A2 filled in the cover unit 211D. The pressure-sensitive electric unit 211A2 is arranged at both ends of the pressure-sensitive unit 211A and connected. The other end of the pressure-sensitive electric unit is connected to the peripheral readout circuit 220 through an interlayer interconnection 211A3. The temperature sensor in this embodiment is an infrared temperature sensor, which is arranged above the pressure sensor unit, and specifically includes a far-infrared heat absorption device 211B1. A suspended far-infrared heat absorption device 211B1 is arranged in the cavity unit 211C, which absorbs thermal radiation and converts it into an electrical signal. The far-infrared heat absorption device 211B1 is a thermistor. The thermistor is connected to the peripheral readout circuit 220 through the bridge connection unit 211B2 and the interlayer interconnection, and transmits the electrical signal to the peripheral readout circuit 220. The above structure is formed by semiconductor manufacturing process, and the bridge connection can be formed by MEMS process.

[0026] like Figure 3As shown, in another embodiment, the composite functional sensor array group 210 further includes a light irradiation unit 230 and an in-situ micro-light irradiation tube 250. The in-situ micro-light irradiation tube 250 is used to guide the light waves of the external light irradiation unit 230 into and pass through the cavity unit 211C and the cover unit 211D. Thus, the in-situ light reflection signals of the skin, blood vessels and blood penetrate the cover unit 211D and the cavity unit 211C, are absorbed by the far-infrared heat absorption device 211B1 and converted into electrical signals and output to the peripheral readout circuit. Therefore, the pulse diagnosis device of the present invention can simultaneously detect the pulse pressure and temperature, and can also provide local illumination to the blood flow inside the skin and blood vessels, thereby obtaining the light reflection signal of the blood flow, and can also obtain a blood flow map. In this embodiment, the far-infrared heat absorption device 211B1 is the light detection unit.

[0027] In a preferred embodiment of the present invention, the length of the sensor group is between 0.5 and 2 cm, and each sensor group is a cube with a side length between 20 and 200 microns.

[0028] In a preferred embodiment of the present invention, the capping unit 211D of the pressure-sensitive unit 211A1 is made of high-resistance silicon, the pressure-sensitive unit is made of metal microwires or high-concentration doped examples implanted by ions in a silicon substrate, and the composite functional sensor array group 210 is a silicon-based semiconductor device.

[0029] In a preferred embodiment of the present invention, the light emitted by the light irradiation unit is short-wave infrared light with a wavelength between 0.75 and 2 microns, so it can penetrate the silicon-based capping unit, while near-infrared short-wave infrared light irradiation can be more penetrating to the skin than visible light.

[0030] In addition, Figure 4 As shown, the present invention also provides a wearable device, in which the pulse diagnosis device is constructed inside the wearable device, such as a smart watch or a wristband. The wearable device also includes a touch display 310 connected to the pulse diagnosis device, a processor 320, a memory 360, a digital-to-analog conversion module 340, and a wireless transceiver module 350. The processor 320 is connected to the pulse diagnosis device to obtain the pulse data of the human body, send it to the touch display for display, and obtain control data from the touch display and send it to the pulse diagnosis device to control its internal data sampling. The processor is also connected to the memory for data storage. The processor is also connected to the digital-to-analog wireless converter to convert the digital signal data into radio frequency analog data. The analog-to-digital wireless converter is also connected to the wireless transceiver, so that the data can be transmitted wirelessly.

[0031] like Figure 5 As shown, the pulse diagnosis device of the present invention is implanted and integrated into a smart watch to form an extended smart wearable system and expand its applications in health care, real-time monitoring of physical condition, and telemedicine.

[0032] When in use, the fixing device makes the pulse diagnosis device contact with the skin inside the wrist. The pulse diagnosis device is restrained by the watch strap and pressed against the skin of the wrist. The body under the skin is the artery. The arterial blood flow generates a certain pulse under the drive of the heart, which is a local high-pressure blood flow and is transmitted upward through the body to the skin, so that the three composite functional sensor array groups of the device produce induction.

[0033] The pulse diagnosis device includes three pressure adjustment devices, which correspond to the composite functional sensor array groups one by one, and simulate the action of taking the pulse with human fingers by applying pressure.

[0034] Therefore, the pulse diagnosis device can collect pressure, temperature, humidity, vibration, etc. at the same time.
