We present and analyze the transmittance characteristics of displacement sensors based on S-curved and tapered single-mode optical fibers. We compare the sensitivity of the S-curved tapered fiber sensor, with respect to the sensitivity of the tapered fiber without prior curvature. The results show sensitivities of up to 192 pm / µm for the S-type sensors relative to sensitivities of the order of 100 pm / µm for the simply tapered sensors.
