Problems solved by technology

The core components of electrical sensors are pressure sensors, strain sensors or acceleration sensors, but they are expensive and have complex structures
Radio sensors use radar waves to monitor respiration and heart rate, and there is a problem that the signal is easily overwhelmed by body motion noise
Optical sensors mainly use fiber optic interference and fiber grating technology, but their structure is not compact enough, requiring fiber optic looper and more complex demodulation technology

Abstract

The invention provides a body movement sensor for an intelligent electrocardiograph monitor. The body movement sensor comprises an input waveguide, a mode separation converter, a cantilever arm waveguide, a sensing unit, a coupling grating and a wavelength demodulator, the input waveguide is used for introducing input light; the mode separation converter is used for carrying out fundamental mode conversion on input light; the cantilever arm waveguide is used for generating vibration according to body movement of a human body; the sensing unit is used for converting input light meeting phase matching; the coupling grating is used for radiating input light which does not meet phase matching in the sensing unit to an outer space; and the wavelength demodulator is used for acquiring energy change according to the wavelength change of the input light. The body motion sensor has the advantages of being compact in size, low in price, insensitive to temperature and easy to integrate, and has important significance on popularization of home health monitoring.

Description

technical field [0001] The invention belongs to the technical field of intelligent monitors, and in particular relates to a body motion sensor for an intelligent electrocardiogram monitor. Background technique [0002] When measuring respiration rate and heart rate, traditional monitors need to be in direct contact with the patient's skin. Generally, electrodes are attached to the body, and tape with sensors is attached. Not only does this cause discomfort to the patient, but long-term vital sign parameter measurements cannot be performed on the patient. With "remote", "non-contact", "non-invasive" and "wireless" measurement methods, it is the development trend of the next generation of intelligent monitors. Smart monitors also have the advantages of being portable, inexpensive, and easy to use, opening up a new era for healthcare, rehabilitation care, and elderly care. [0003] The core part of the smart monitor is the "non-contact" body motion sensor, whose function is t...
