With the rapid development and application of smart homes, sensors known as 'neurons' have become more and more important in this field. In response to the demand for relative humidity parameter in home monitoring, a flexible relative humidity sensor based on reduced graphene oxide (RGO) and interdigital electrode for smart homes was designed and prepared in this paper. The base of the interdigital electrode structure was polyimide, and the RGO film was prepared by a spraying process. A test system for the relative humidity sensor with different saturated salt solutions was also built. The test results show that the sensor resistance and relative humidity have a linear relationship in the range of 24.6% RH-82.9% RH, and the linearity is as high as 0.987. The sensitivity of the sensor is 0.51 kΩ/% RH. The relative humidity sensor with the characteristics of flexibility and high sensitivity will have broad application prospects and value in the field of smart homes.

“…Based on Equation (2), when the environmental refractive index increases, the index increment of the

mode is larger than that of the

mode. Thus,

obtain a negative value [ 45 ]. The results show that the interference wavelength of light redshifts as the ambient refractive index increases.…”

Diabetes patients need to monitor blood glucose all year round. In this article, a novel scheme is proposed for blood glucose detection. The proposed sensor is based on a U-shaped microfiber prepared using hydrogen-oxygen flame-heating technology, and then 3-aminopropyltriethoxysilane (APTES) and glucose oxidase (GOD) are successively coated on the surface of the U-shaped microfiber via a coating technique. The glucose reacts with the GOD of the sensor surface to produce gluconic acid, which changes the effective refractive index and then shifts the interference wavelength. The structure and morphology of the sensor were characterized via scanning electron microscope (SEM) and confocal laser microscopy (CLM). The experimental results show that the sensitivity of the sensor is as high as 5.73 nm/(mg/mL). Compared with the glucose sensor composed of the same material, the sensitivity of the sensor increased by 329%. The proposed sensor has a broad application prospect in blood glucose detection of diabetic patients due to the advantages of miniaturization, high sensitivity, and good stability.
