The breath gas analysis through gas phase chemical analysis draws attention in terms of non-invasive and real time monitoring. The array-type sensors are one of the diagnostic methods with high sensitivity and selectivity towards the target gases. Herein, we presented a 2 × 4 sensor array with a micro-heater and ceramic chip. The device is designed in a small size for portability, including the internal eight-channel sensor array. In2O3 NRs and WO3 NRs manufactured through the E-beam evaporator’s glancing angle method were used as sensing materials. Pt, Pd, and Au metal catalysts were decorated for each channel to enhance functionality. The sensor array was measured for the exhaled gas biomarkers CH3COCH3, NO2, and H2S to confirm the respiratory diagnostic performance. Through this operation, the theoretical detection limit was calculated as 1.48 ppb for CH3COCH3, 1.9 ppt for NO2, and 2.47 ppb for H2S. This excellent detection performance indicates that our sensor array detected the CH3COCH3, NO2, and H2S as biomarkers, applying to the breath gas analysis. Our results showed the high potential of the gas sensor array as a non-invasive diagnostic tool that enables real-time monitoring.

Single-crystalline GeS nanoribbons were synthesized by chemical vapor deposition for the first time. The nanoribbon photodetectors respond to the entire visible incident light with a response edge at around 750 nm and a high responsivity, indicating their promising application for high performance broadband visible-light photo-detection.

In order to improve the thermal stability of silicon micro hotplate, a ceramic hotplate with structure of suspending bridge was designed. The steady-state thermal response of the hotplate and the structure of the micro-heater were simulated by using the finite element method. By using conventional microelectronics technology and laser micro processing technology, the microstructures with thickness of 100 μm and bridge width of 2 mm were produced. The test results show that the ceramic hotplate has higher working temperature than traditional silicon hotplate, and it can be worked steadily at the average temperature of 630 °C on 1.5W heating power. Taking ceramic hotplate as heating platform and nano-SnO2 materials with Pd doping concentration of 0.2 at.% and 10 at.% as sensitive materials respectively, the array with two gas sensors was designed and fabricated. The gas sensor array can be used to detect single gas of CO or CH4 with high sensitivity and good selectivity when it works with constant heating voltage. When the sensor array works with periodic voltage heating pulse, it can realize quantitative detection for mixed gases of CO and CH4.

Mechanical Switch

Purpose The purpose of this paper is to analyse the possibilities of mechanical switch replacement by capacitive film touch sensor in applications requiring high reliability and short response time. Advantage of replacing mechanical switch by capacitive touch sensor is no mechanical wear and possible implementation of sensor in application where the switch could not be used or where the flexibility of the sensor substrate is required. The aim of this work is to develop a capacitive touch sensor with the advantage of maximum mechanical resistance, short response time and high sensitivity. Design/methodology/approach Based on various possible sensors layouts, the authors realized 18 different (14 self-capacitance and four mutual capacitance) topologies of capacitive sensor for touch applications. Three different technologies – PCB, LTCC and polymer technology – were used to characterize sensor’s behaviour. For precise characterization of different layouts realized on various substrates, the authors used integrated circuit FDC2214 capacitance-to-digital converter. Findings Sensing range of the capacitive touch (proximity) sensor is affected by the per cent of area covered by the sensor, and it does not depend on topology of sensor. The highest sensing range offers PCB technology. Flexible substrates can be used as proper substituent to rigid PCB. Originality/value The novelty of this work lies in finding the touch capacitive sensors that allow shorter switching times compared to standard mechanical switches.
