Flexible pressure sensor and pulse diagnosis instrument

Abstract

The invention relates to the technical field of sensors, and discloses a flexible pressure sensor and a pulse diagnosis instrument. The flexible pressure sensor comprises a first electret layer, a second electret layer, an interlayer, a first electrode layer and a second electrode layer, wherein the interlayer is fixed between the first electret layer and the second electret layer, the first electrode layer is fixed to the first electret layer, the second electrode layer is fixed to the second electret layer, and a plurality of through holes are formed in the interlayer. The pulse diagnosis instrument comprises the flexible pressure sensor, and further comprises a wristlet, the wristlet is arranged outside the flexible pressure sensor to fix the flexible pressure sensor on a position to bemeasured. The flexible pressure sensor is small in thickness, good in flexibility, high in sensitivity and accurate in measuring result; and the pulse diagnosis instrument can accurately acquire pulse wave signals of a human body, is easy to completely joint with skin, and does not easily cause discomfort after being worn for a long term.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a flexible pressure sensor and a pulse diagnosis instrument. Background technique [0002] As a detection device, the sensor can sense the measured information, and convert the sensed information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, and recording. and control requirements. The pressure sensor is a relatively common type of sensor, which is widely used in many fields. The pressure sensor mainly uses the piezoelectric effect to work, can sense the external pressure signal, and convert the pressure signal into an output electrical signal according to certain rules. Today, wearable measuring devices for human health detection have gradually entered our lives to accurately monitor our physical health and bring us great convenience. Th...

Problems solved by technology

[0003] However, most of the sensors used in the current detection equipment are hard sensors, which are not flexible enough and have a large thickness.

Therefore, when worn, it cannot fully fit the human body to be measured, resulting in the inability to achieve high sensitivity, and it is difficult to accurately capture some weaker physiological signals, thereby greatly limiting the accuracy of the measurement results, and It will affect the comfort when wearing and is not suitable for long-term use
