Abstract

In various chemical sensing applications, rapid measurement of analyte concentrations is essential. While estimating the equilibrium response from initial transient responses provides a practical and cost-effective solution, existing techniques often involve extensive data, complex algorithms, or inefficiencies. This study presents a discrete multiplierless first-order differentiation method designed to expedite the measurement of NH3 gas concentration using a resistive gas sensor composed of SnS2 nanostructures at room temperature (25 ± 3 °C). This method significantly reduces stabilized response measurement time by transforming the sensor’s monotonically changing response into a non-monotonic one and associating the resulting peaks with NH3 gas concentration. Specifically, it makes gas concentration determination 85–94 % faster for concentrations ranging from 42 to 105 ppm than traditional steady-state measurements. This enhanced speed makes the method well-suited for resource-limited applications requiring rapid analyte quantification.
加速电阻传感器中目标分析物的测量:SnS2气体传感器的无乘法器一阶微分法
在各种化学传感应用中,分析物浓度的快速测量是必不可少的。虽然从初始瞬态响应估计平衡响应提供了一种实用且经济的解决方案,但现有技术通常涉及大量数据,复杂的算法或效率低下。在室温(25 ± 3°C)下,利用SnS2纳米结构组成的电阻式气体传感器,提出了一种离散无乘法器一阶微分方法,以加快测量NH3气体浓度。该方法通过将传感器单调变化的响应转变为非单调变化的响应,并将产生的峰值与NH3气体浓度相关联,显著缩短了稳定响应测量时间。具体来说,它使气体浓度测定85-94 %,浓度范围从42到105 ppm比传统的稳态测量快。这种提高的速度使该方法非常适合需要快速分析物定量的资源有限的应用。

期刊介绍: Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
