“…[11][12][13][14][15][16] Among these, great attention has been paid to the electrochemical sensors for the quantication of pesticide residues because of their unique features such as cost-effectiveness, rapidity and high sensitivity. [17][18][19][20][21][22][23][24][25] The efficiency of the electrochemical sensors largely depends on the electrode material, highlighting the need to obtain new electrode materials with good properties. To this end, noble metal materials and alloy metals are appropriate candidates for the surface modication of electrodes, but they have a high cost.…”

“…The sensor can simultaneously measure temperature and pressure and can achieve temperature compensation at high temperatures. Jun Lin et al [25] analyzed the impact of temperature on the sensitivity and amplitude frequency characteristics of sensors, and based on the theoretical formula model of transfer functions and experimental data, established a temperature drift model of sensors and provided a temperature compensation model for sensitivity.…”

Weighing-In-Motion (WIM) technology is one of the main tools for pavement management. It can accurately describe the traffic situation on the road and minimize overload problems. WIM sensors are the core elements of the WIM system. The excellent basic performance of WIMs sensor and its ability to maintain a stable output under different temperature environments are critical to the entire process of WIM. In this study, a WIM sensor was developed, which adopted a PZT-5H piezoelectric ceramic and integrated a temperature probe into the sensor. The designed WIM sensor has the advantages of having a small size, simple structure, high sensitivity, and low cost. A sine loading test was designed to test the basic performance of the piezoelectric sensor by using amplitude scanning and frequency scanning. The test results indicated that the piezoelectric sensor exhibits a clear linear relationship between input load and output voltage under constant environmental temperature. The linear correlation coefficient R2 of the fitting line is up to 0.999, and the sensitivity is 4.04858 mV/N at a loading frequency of 2 Hz at room temperature. The sensor has good frequency-independent characteristics. However, the temperature has a significant impact on it. Therefore, the output performance of the piezoelectric ceramic sensor is stabilized under different temperature conditions by using a multivariate nonlinear fitting algorithm for temperature compensation. The fitting result R2 is 0.9686, the root mean square error (RMSE) is 0.2497, and temperature correction was achieved. This study has significant implications for the application of piezoelectric ceramic sensors in road WIM systems.

“…However, their work did not put forward an effective temperature compensation method, and the temperature characteristic for lower frequencies were not studied. Lin Jun from the Jilin University conducted studies of temperature compensation on the MTLS10 electrochemical seismic sensor [ 14 ]. Their study tested the sensitivity curves with a temperature range of 10 °C ~ 45 °C, and developed a temperature coefficient model, which corrected the temperature sensitivity through a mathematical model.…”

Electrochemical seismic sensors that employ liquid as their inertial masses have the advantages of high performances in the low-frequency domain and a large working inclination. However, the surrounding temperature changes have serious impacts on the sensitivities of the sensors, which makes them unable to work as expected. This paper studied the temperature characteristics of electrochemical seismic sensors based on MEMS (micro–electro–mechanical systems), and analyzed the influences of the temperature effects on the open-loop and closed-loop amplitude-frequency curves. Most importantly, the temperature compensation circuits based on thermistors were developed, which effectively adjusted pole frequencies and sensitivity coefficients, and finally realized the real-time temperature compensation for both open-loop and closed-loop measurements for the first time. The results showed that in the temperature range of −10 °C ~ +40 °C, and with the 3 dB bandwidth range of 0.01 Hz ~ 40 Hz, the change of the maximum sensitivity was reduced from about 25 dB before temperature compensation to less than 2 dB after temperature compensation.
