PVDF (Polyvinylidene Fluoride) flexible film body temperature and cardiac sound integrated sensor

Abstract

The invention discloses a PVDF (Polyvinylidene Fluoride) flexible film body temperature and cardiac sound integrated sensor, which comprises a cardiac sound detection cavity holder, wherein the edge of a cardiac sound PVDF film adheres to the upper end of the cardiac sound detection holder, and seals the upper end of the cardiac sound detection cavity holder; an insulated fixed holder sleeves the periphery of the cardiac sound detection cavity holder, and a cardiac sound electrode is mounted at the upper end of the insulated fixed holder and adheres to the outer side of the cardiac sound PVDF film by means of conductive adhesive; a body temperature electrode sleeves the lower end of the insulated fixed holder, and a body temperature PVDF film adheres to the body temperature electrode by means of conductive adhesive; wires are soldered on both the cardiac sound electrode and the body temperature electrode. Not only can the PVDF flexible film body temperature and cardiac sound integrated sensor dynamically detect a body temperature signal and a cardiac sound signal and prevent the interference between the body temperature signal and the cardiac sound signal, but also the cardiac sound PVDF film can directly touch the chest skin alone to only detect the cardiac sound signal . The PVDF flexible film body temperature and cardiac sound integrated sensor has the characteristics of mature basic theory, wide application, low cost, reusability, batch production, simple manufacturing process, long service life and convenience and flexibility in use.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a PVDF flexible film body temperature heart sound integrated sensor. Background technique [0002] Polyvinylidene fluoride (PVDF) flexible films have begun to be used in medical imaging, medical diagnosis, medical ultrasound transducers, etc. However, most medical physical sensors can only measure the medical parameters of a single organism, and it is difficult to achieve integrated measurement of parameters. Therefore, the integrated detection of multiple parameters has always been the research theme and focus of the majority of medical rehabilitation researchers and biomedical device researchers. It has been more than 100 years since Curie discovered the piezoelectric effect in 1880. In 1969, Dr. Heiji Kawai of Japan discovered the piezoelectric effect of PVDF. Since then, people have continued to study various characteristics and effects of PVDF films. At...
