“…The sensing mechanism of the sensor can be attributed to the mixed potential principle. ,,, First, a mass spectrometer was used to analyze the reaction products of isoprene; Figure S5 compares the gas component before and after isoprene introduced. After isoprene was introduced, an increase in the content of CO and H 2 O was observed.…”

“…However, the load of Au increases the basic resistance of the sensor nearly 10 times to the level of GΩ, which is detrimental to signal detection. In contrast, sensors based on the mixed potential sensing mechanism present incomparable advantages in stability and humidity resistance, which have been confirmed in the highly stable detection of NO x , − SO 2 , , NH 3 , and volatile organic compounds (VOCs) − gases. Unfortunately, there are still very limited reports on mixed potential gas sensors for isoprene detection.…”

Monitoring of isoprene in exhaled breath is expected to provide a noninvasive and painless method for dynamic monitoring of physiological and metabolic states during exercise. However, for real-time and portable detection of isoprene, gas sensors have become the best choice for gas detection technology, which are crucial to achieving the goal of anytime, anywhere, human-centered healthcare in the future. Here, we first report a mixed potential type isoprene sensor based on a Gd2Zr2O7 solid electrolyte and a CdSb2O6 sensing electrode, which enables sensitive detection for isoprene with sensitivities of −21.2 mV/ppm and −65.8 mV/decade in the range of 0.05−1 and 1−100 ppm. The sensing behavior of the sensor follows the mixed potential sensing mechanism and was further verified by the electrochemical polarization curves. The significant differentiation between the sensor response to exhaled breath of healthy individuals and simulated breath containing different concentrations of isoprene demonstrates the potential of the sensor for the detection of isoprene in exhaled breath. Simultaneously, monitoring of isoprene during exercise signifies the feasibility of the sensor in dynamic monitoring of physiological indicators, which is not only of great significance for optimizing training and guiding therapeutic exercise intervention in sporting scenarios but also expected to help further reveal the interaction between exercise, muscle, and organ metabolism in medicine.

“…10b), meaning that the sensor response conforms to the mixed potential mechanism. According to the theory of mixed potential, [14][15][16]25,26 when the sensor is exposed to NH 3 in the presence of O 2 , the anodic reaction of NH 3 (1) and the cathodic reaction of O 2 (2) proceed simultaneously at the interface of In 2 O 3 -SE/YSZ. The mixed potential was established when the rates of reactions 1 and 2 were equal.…”

“…[9][10][11][12][13][14] Among them, the mixed potential type sensor based on yttriastabilized zirconia (YSZ) solid electrolyte is regarded as the most promising sensing device in NH 3 detection due to its simple design, low cost, and strong resistance to harsh operating environments (high temperature, high humidity) such as exhaust. [15][16][17][18][19][20] Based on the sensing mechanism of the mixed potential type sensor, the conductivity, catalytic and electrochemical activity of the sensing electrode material are crucial in achieving high performance. Thus far, various types of sensing materials have been reported as promising candidates for the detection of NH 3 , such as noble metals, metal oxides, and composite materials.…”

In2O3 material with special morphology was synthesized using the hydrothermal method and used as the sensing electrode for a mixed potential ammonia sensor based on yttria-stabilized zirconia electrolyte. The In2O3 sensing electrode (In2O3-SE) was sintered at different temperatures and was characterized by X-ray diffraction and field-emission scanning electron microscopy. The influence of the In2O3-SE sintering temperature on the performance of the sensor was investigated by testing the NH3 response at 500°C. The results showed that the sensor attached with In2O3-SE sintered at 900°C exhibited the largest response value (–102.1 mV for 250 ppm NH3) at 500°C. Moreover, the response value of the sensor varied almost linearly with the logarithm of NH3 concentration in the range of 20–400 ppm, which was consistent with the mixed potential mechanism, as verified by polarization and electrochemical impedance spectroscopy tests. Furthermore, the sensor also displayed high sensitivity to NH3, but weak cross-sensitivities to various interfering gases (CHs, NOx, CO, CO2 and H2O) at 500°C. It exhibited slight signal drifts both in the continuous 26-hour test and in the interval test over a period of one month, which showed that the sensor attached with 900°C-sintered In2O3-SE has acceptable short- and long-term stability.

“…Chemical sensors are widely applied in gas detection, which has the advantages of low cost and small size [5]. However, when chemical sensors are employed to detect NH 3 , it may be influenced by other gasses, such as oxygen [6]. Laser absorption spectroscopy (LAS) is an effective method with the advantages of being non-invasive, highly sensitive, having a fast response, and selective detection, and has been widely used for trace gas sensing.…”

This invited paper demonstrated an ultra-highly sensitive ammonia (NH3) sensor based on the light-induced thermoelastic spectroscopy (LITES) technique for the first time. A quartz tuning fork (QTF) with a resonance frequency of 32.768 kHz was employed as a detector. A fiber-coupled, continuous wave (CW), distributed feedback (DFB) diode laser emitting at 1530.33 nm was chosen as the excitation source. Wavelength modulation spectroscopy (WMS) and second-harmonic (2f) detection techniques were applied to reduce the background noise. In a one scan period, a 2f signal of the two absorption lines located at 6534.6 cm−1 and 6533.4 cm−1 were acquired simultaneously. The 2f signal amplitude at the two absorption lines was proved to be proportional to the concentration, respectively, by changing the concentration of NH3 in the analyte. The calculated R-square values of the linear fit are equal to ~0.99. The wavelength modulation depth was optimized to be 13.38 mA, and a minimum detection limit (MDL) of ~5.85 ppm was achieved for the reported NH3 sensor.
