Abstract

The practical realization of low Young's modulus Polyurethane (PU) based optical fibers offers new possibilities for sensing on bodies due to its bio-compatibility and high material sensitivity. Here, we experimentally demonstrate a PU fiber pressure sensor using the simplest possible structure (i.e. a capillary) to measure a weak low frequency signal comparable to respiration/heart rate. We characterized the fiber and measured the sensitivity of a PU capillary using a speaker connected to a function generator. The frequency of the modulated signal was recovered using Fourier Transform (FT). This bodes well for applying more sophisticated structures to wearable devices.
