Design and Implementation of Communication and Healthcare Sensors

Abstract

Communication and health care sensors have contributed greatly to patients and medical workers, through first, with the existence of the Covid-19, the hospital beds are unlikely to meet all infected patients, as communication and health care sensors can be used to monitor the patient's vital signs such as (temperature, pressure, Electrocardiogram..) in the hospital wherever the patient is and can be used as an automatic pandemic transmission of an alert signal from the personal servant to the emergency center by monitoring the changes in the vital signs of the individual. Secondly, to connect patients with 24-hour caregivers via the network according to the patient's needs. Thirdly, it can be used to monitor stable chronic patients who have been discharged from hospitals at home as not every patient can afford a home visit by nurses or doctors. An optical fiber sensor for monitoring the vital signs of the patient had been submitted; the temperature had been chosen to be measured. In this research the experimental and simulation by using opt-system program was done. Two different types of optical fiber were chosen as a sensing media; Fiber Bragg Grating FBG (1550nm wavelength, 20nm band width, and 10^-3 w power) and single mode fiber (SMF), water bath which used to measure the temperature by FBG or SMF sensor for (36–40) C⁰. The Optical Spectrum Analyzer (OSA) recorded the input and output spectra. Then the results send as data using Free Space Communication System. The submitted sensors show a very good sensitivity towards temperature, for FBG sensor, the sensitivities 10.5 pm/ C⁰ and -8.5 pm/ C⁰ while the sensitivity for SMF sensor 5 pm/ C⁰ and -5.5 pm/ C⁰ for heating and cooling temperature respectively.
