note = "Funding Information: In this paper, a novel rotation sensor based on a fiber-tapered fabricated with commercially available TA-MCF was proposed and demonstrated for torsion measurement. Eight measurement ranges centered at different angles were characterized and the sensitivity can be enhanced to as high as 1.1 nm/°. As a result, different wavelength shift in various measurement ranges was observed, which makes this kind of sensor flexible for twist sensing with tunable sensitivity. Torsion measurement under clockwise and counter clockwise direction was performed to show its discrimination of the rotation direction. We repeat the twist sensing experiment to verify its repeatability. Further improvement as well as the theoretical analysis are under investigation and will be presented at the conference.
