Analysis of encapsulation the fiber Bragg sensors for biomedical applications

摘要

The publication describes the use of fiber-optic Bragg sensors in biomedical applications. Fiber-optic sensors are characterized by the immunity to electromagnetic interference (EMI) and by the electrical passivity. Currently, these types of sensors are increasingly being used in biomedical applications, for example, for measuring the temperature or the heart and respiratory rate of the human body. It is very important to encapsulate these types of sensors because encapsulation itself has a major effect on the sensor functionality. This publication describes a comparison of two materials - polymer polydimethylsiloxane (PDMS) and fiberglass (fiberglass is a composite material made up of glass fiber (fabric) and cured synthetic resin). The comparison was conducted by a series of laboratory experiments with ten volunteers with their written consent. Acquired data were compared by the Bland-Altman method.
