This investigation studies the use microbottle resonator (MBR) as ethanol liquid sensor. This resonator made-up from silica fiber SMF28 using process recognized as “soften- and-compress” to form bottle structure with a diaphragm diameter D b = 170μm , stem diameter of D s = 125μm and bottle length L b = 180μm. The MBR characterized by via 3μm tapered microfiber and bright to have >10 4 for the quality factor value (Q-factor). The MBR was formerly used as ethanol liquid sensor for the range between 10% to 100% and compared with non-MBR microfiber for wide-ranging performance. The MBR sensor was initiate to have a sensitivity 0.1756 dB/%ppm with linearity 99.28% and standard deviation of 3.355 dB, which was exceptional compare to the non-MBR microfiber in all limitation measured.
