Problems solved by technology

Existing pulse sensors all adopt a single-point measurement method. Although this single-point measurement method is simple and easy to implement, the deviation of the placement position of the pulse sensor on the wrist will have a great impact on the measurement signal, and the pulse of this single-point measurement None of the sensors can simulate the three diagnostic methods during palpation

Embodiment Construction

[0017] A PVDF array tactile sensor for pulse measurement, comprising a metal substrate 1, a central PVDF piezoelectric film 2 is provided in the central area of ​​the metal substrate 1, a first PVDF piezoelectric film 3 and a first PVDF piezoelectric film 3 are provided in the edge area of ​​the metal substrate 1 The second PVDF piezoelectric film 5 . Although the above-mentioned technical solution can solve the problem of one-time collection of pulse signals at the inch, close, and ruler positions, the above-mentioned pulse sensor composed of only three PVDF piezoelectric films has very strict requirements on the placement angle of the sensor when collecting pulse signals. , The three PVDF piezoelectric films must be aligned with the inch, close, and ruler positions, and a slight deviation will cause distortion of the measurement signal. Therefore, the present embodiment adopts the following technical measures to solve the above-mentioned problems: a third PVDF piezoelectric ...

Abstract

The invention discloses a PVDF array tactile sensor for comprehensive and accurate pulse measurement, which includes a metal substrate, a central PVDF film is arranged in the central region of the metal substrate, and a first PVDF pressure sensor is arranged in the edge region of the metal substrate. Electric thin film, second PVDF piezoelectric thin film, third PVDF piezoelectric thin film and fourth PVDF piezoelectric thin film. Compared with the prior art, the PVDF array tactile sensor for pulse measurement of the present invention has the following advantages: due to the use of a circular PVDF piezoelectric film in the middle and a symmetrical and annular structure of four arc-shaped strip-shaped PVDF piezoelectric films around it, this When the symmetrical structure is in use, the placement angle of the pulse sensor at the incision site of the wrist will not affect the signal acquisition, and the measured pulse information is comprehensive and accurate.

Description

technical field [0001] The invention relates to a pulse sensor, in particular to a PVDF array tactile sensor for measuring pulse. Background technique [0002] For more than two thousand years, Chinese medicine has accumulated rich experience in pulse diagnosis, which is a treasure of the Chinese nation. However, due to the limitation of historical conditions, various pulse conditions in traditional Chinese medicine can only be described qualitatively, and Duobi is regarded as a natural phenomenon. For example, the Xianmai is compared to "like a bow string", and the floating mai is compared to "like water drifting wood", etc. Because it can only be described qualitatively, and different doctors have different understandings of natural landscapes, the technique of pulse detection is complicated and difficult to master, and the techniques of pulse detection are also different, which leads to differences in pulse analysis. With the development of society, there is an urgent n...
