High sensitivity protable capacitive humidity sensor based on In2O3 nanocubes-decorated GO nanosheets and its wearable application in respiration detection

Publication date: 15 November 2019Source: Sensors and Actuators B: Chemical, Volume 299Author(s): Bolun Li, Qi Tian, Hongxin Su, Xingwei Wang, Tianen Wang, Dongzhi ZhangAbstractPortable humidity sensors fabricated in wearable devices have promising application in disease diagnostics and personal health monitoring. In this work, a capacitive humidity sensor based on indium oxide (In2O3) nanocubes/graphene oxide (GO) nanosheets hybrid film was developed with Cu/Ni electrodes on an epoxy substrate. The In2O3/GO composite was analyzed through XRD, SEM, TEM and XPS for its composition, morphology and structure. The In2O3/GO film sensor was exposed to a wide range of relative humidity and its characteristics of capacitance performance with humidity were found to be better than humidity sensors based on pristine In2O3 or GO in terms of sensitivity, stability, response and recovery times. Meanwhile, a low-cost humidity and respiration monitoring system was developed on a print circuit board (PCB) based on STM32F405RGT6 microcontroller and Android Mobile APP. The curve of humidity and capacitance value can be shown on the smartphone, which can distinguish whether a person is breathing normally. The respiration detector designed holds great potential in the monitoring of asthma and irregular respiratory diseases due to its portability, instantaneity, accuracy and low power consumption.

Authors: Salhi M, Lahmar O, Salah MO, Banić I, Binghao B, Malik W, Hamzaoui K, Turkalj M, Hamzaoui A Abstract OBJECTIVE: Pharmacogenetic studies have recognized specific genes that highly correlate with response to inhaled corticosteroids (ICS) treatment in asthma patients. Among the genes identified, we selected glucocorticoid-induced transcript 1 (GLCCI1) and stress-induced phosphoprotein 1 (STIP1) to evaluate the impact of these gene polymorphisms on ICS treatment response in Tunisian asthmatics. METHODS: We analyzed four single nucleotide polymorphisms (SNPs): two in GLCCI1 (rs37972 and rs37973), and two i...

Methods: Patients enrolled in this study were distributed randomly into a treatment group (tratinterol hydrochloride) and an active control group (procaterol hydrochloride) and were treated for 2 weeks after running-in. The end points were changes in pulmonary function and clinical sympt...

ConclusionThere is moderate evidence that high doses of ICS, in addition to SCS, reduces the risk of hospital admission in ED treatment of moderate to severe asthma exacerbations. Further research is required to determine their optimal role in both ED and outpatient settings.

Cucurbitacin E (CuE), a tetracyclic triterpene isolated from Cucurbitaceae plants, has been recently proved to exert anti-inflammation and immunology regulation activities. Nevertheless, its roles in asthma remains poorly defined. In the current study, CuE had little cytotoxicity on cell viability of human bronchial epithelial...
