abstract = "An innovative application of lossy mode resonances (LMRs) is presented in this work, pursuing the detection of biomedical variables. In this case, the detection of pH and breathing signal events is shown by means of a reflective fiber-optic optrode consisting of a poly(allylamine chloride) / poly (acrylic acid) polymer matrix deposited on the tip of a 200-micron-core bare multimode optical fiber. The proposed sensor is capable of detecting pH values between 6.5 and 8.0 (saliva pH range) with quite stability and repeatability. Moreover, when monitoring the breathing signal, the proposed sensor presents quite good real time detection of the different events occurring during the inspiration-expiration cycle, different breathing rates and detecting apneas.",
