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 which can fully collect information and accurately measure pulse. The sensor comprises a metal substrate, a central PVDF thin film which is arranged at a central area of the metal substrate, and a first PVDF piezoelectric thin film, a second PVDF piezoelectric thin film, a third PVDF piezoelectric thin film and a forth PVDF piezoelectric thin film which are arranged at an edge area of the metal substrate. Compared with the prior art, the PVDF array tactile sensor for measuring the pulses has the following advantages: a symmetrical and annular structure with a circular PVDF piezoelectric thin film at the center and four arc-shaped PVDF piezoelectric thin films at the edges is used, thus the position angle of a pulse sensor on the pulse-feeling and palpation part of the wrist does not affect the signal collection, and the pulse information can be fully and accurately measured.

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...
