More Information
Summary:The invention belongs to the technical field of pulse feeling systems, and particularly relates to a pulse feeling system based on a pressure sensor. The three groups of graphene micro-strain sensors are independently arranged in the outer shell and are used for detecting characteristic information of pulse waves; the three groups of independently arranged pressurizing assemblies are used for applying force to the graphene micro-strain sensor; according to the pulse feeling system based on the pressure sensor, the ultrasonic transducer and the piezoelectric film are combined with the signal amplification circuit, and the piezoelectric film is light, flexible, easy to prepare, good in impedance coupling with human tissue, capable of being tightly attached to the skin, low in mechanical quality factor, small in damping and low in density, has the broadband characteristic and meets the frequency characteristic of pulse signals; and the pulse signal is not depolarized in a very high alternating electric field, so
