This paper presents the comparison of fibre-optic Bragg Grating Sensor with the commercially available probes for heart sounds measurement based on microphones. The analysis of the sensitivity and specificity was carried out to assess the efficacy of the individual measuring probes. Since fibre-optic sensing uses light in optical fibre rather than electricity, it solves the limitations of electrical sensors such as transmission loss and susceptibility to electromagnetic interference (EMI). Experimental results have shown that Fibre-Optic Bragg Grating Sensor significantly outperforms the devices using the microphones. Moreover, the sensor embedded in polydimethylsiloxane polymer and is fixed on the thorax by means of elastic belt. The material is biocompatible and immune to electromagnetic interference, which is major advantage for the healthcare environment. The probe dimensions are small; therefore, it would be convenient for the patient and easily implemented into clinical practice. Nevertheless, the signal processing methods must be applied to separate the desired signal from the environmental noise.
