Technical Field
The utility model relates to the technical field of sensors, specifically a pulse condition sensor based on flexible gasbag encapsulation.
Background
The pulse condition sensor is an important component of the pulse condition instrument, mainly plays a role in sensing pulse pressure and collecting pulse condition data, and is the most key interface of a human body and the pulse condition instrument. The performance of the pulse condition sensor directly determines the pulse data quality, and thus the pulse condition test result. The pulse condition sensor not only needs to have better sensitivity, linearity and precision, but also needs to have wide applicability and usability, thereby reducing the influence of the human body pulse position difference and the wrist structure difference on the measurement.
At present, the mature pulse condition sensor products available in the market are few and are mostly in the research stage. The main reasons restricting the development of pulse condition sensors are: the pulse position of each person and the tissue structure around the pulse position have large individual difference, and the existing sensor is difficult to adapt to the ubiquitous difference. Most of the pulse condition sensors that have appeared at present are piezoelectric sensors, piezoresistive sensors, MEMS sensors, cantilever beam sensors, and the like. For example: HK-2000G and HK-2018 sensors of Hefei Huake, and the like. The sensors, whether used individually or arranged in a matrix form, are limited by the size and shape of the sensors, and cannot be matched with the actual conditions of different users, so that the measurement error is large, and the measurement consistency is poor. In addition, the matrix sensor is often with higher costs, is unfavorable for using widely by a large scale.
