Abstract

Pulse wave measurement is a method of biomedical diagnostics, allowing to predict many health problems. It is however vital for the healthcare system to bring this technology to mass-market while ensuring high measurement accuracy. Therefore, the development of novel cost-effective pulse wave sensors with increased accuracy and reduced susceptibility to motion artifacts is of great importance. This work reports on a pulse wave optical fiber sensor, interrogated by a smartphone. The sensor performance was tested in terms of signal to noise ratio, repeatability of demodulated signal and suitability of demodulated signals for extraction of information about direct and reflected waves.
