Flexible pulse sensor and detection method

Abstract

The invention discloses a flexible pulse sensor and a detection method. The flexible pulse sensor comprises a flexible conductive substrate, a flexible sensitive layer and a sensing layer which are sequentially stacked from bottom to top, the flexible sensitive layer comprises three-finger electrodes which are arranged side by side at intervals and used for taking pulses, and the three-finger electrodes correspond to the three pulse taking positions of the cun pulse, the guan pulse and the chi pulse in traditional Chinese medicine respectively. According to the flexible pulse sensor, the three-finger electrodes are arranged to simulate the three pulse taking positions of the cun pulse, the guan pulse and the chi pulse in traditional Chinese medicine pulse diagnosis so as to collect pulse signals at the radial artery of a wrist of a human body, the physical health of the human body is judged by analyzing the pulse signals at the radial artery, and thus objectivity of traditional Chinesemedicine pulse diagnosis is improved; and the three parts of the cun pulse, the guan pulse and the chi pulse at the radial artery are subjected to pulse taking simultaneously, and thus the detectionsensitivity of the pulse signals of the human body is greatly improved. The flexible pulse sensor is simple in structure, light and portable in texture, not prone to falling off, low in manufacturingcost, easy to operate, and stable and reliable in detection result.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a flexible pulse sensor and a detection method thereof. Background technique [0002] Pulse condition is a symbol of human arterial rhythm, speed, size, strength, ups and downs, virtual reality, etc. The human pulse condition is regarded as the language of life by Chinese medicine because it contains rich health status information, and thus has received more and more attention from Chinese and foreign medical circles. The comprehensive information such as waveform, amplitude, wave velocity and cycle presented by the pulse wave reflects many blood flow characteristics in the human cardiovascular system to a large extent. [0003] At present, there are also some reports on wearable medical fabrics used to monitor physiological signals at home and abroad, such as the "life shirt" developed by VivoMetrics in the United States, which can reflect the wearer's breathing situation and re...

Problems solved by technology

[0006] The study found that the existing mechanical structure of the pulse detection system of traditional Chinese medicine is mainly a wristband structure, which will block the pulse fluctuation when the pressure is higher than a certain value, and cannot truly restore the "floating and sinking" pulse diagnosis of traditional Chinese medicine. Thought

In addition, most of the existing products are based on single-point pulse wave sensors, whose single-point structure cannot reflect the theoretical point of view of "inch-off-ruler" in traditional Chinese medicine, and requires the user to maintain a stable and calm state when measuring, which has a great impact on the use environment. requirements, thus limiting the popularity of its application

Secondly, most of the traditional Chinese medicine pulse diagnosis instruments currently available on the market are bulky and expensive. They need to combine the professional knowledge of doctors to judge the boundary between disease and non-disease. They are only suitable for use in large hospitals and cannot be extended to the general population. Unable to meet market demand
