High-Performance Temperature Sensor by Employing Screen Printing Technology

Abstract

In the present study, a high-performance n-type temperature sensor was developed by a new and facile synthesis approach, which could apply to ambient temperature applications. As impacted by the low sintering temperature of flexible polyimide substrates, a screen printing technology-based method to prepare thermoelectric materials and a low-temperature heat treatment process applying to polymer substrates were proposed and achieved. By regulating the preparation parameters of the high-performance n-type indium oxide material, the optimal proportioning method and the post-treatment process method were developed. The sensors based on thermoelectric effects exhibited a sensitivity of 162.5 μV/°C, as well as a wide range of temperature measurement from ambient temperature to 223.6 °C. Furthermore, it is expected to conduct temperature monitoring in different scenarios through a sensor prepared in masks and mechanical hands, laying a foundation for the large-scale manufacturing and widespread application of flexible electronic skin and devices.

A High-Precision Three-Dimensional Probe Array Temperature Sensor

“…Heat treatment is a common method to modify thin films [10,12,24]. In this work, based on the process preparation parameters in Table 2, heat treatment of the prepared film was carried out at different time and temperature parameters.…”

“…The observation of temperature deviations, fluctuations, etc., can also be used to monitor the status of drugs, and blood [3][4][5][6][7][8][9][10][11]. In the electromechanical field, for auxiliary facilities such as power generation mainframe equipment, engine propellers, and hydraulic oil, accurate temperature measurements are required to monitor the operation of the system and thus ensure the proper operation of the project [12][13][14][15].…”

Flexible temperature sensor with high sensitivity ranging from liquid nitrogen temperature to 1200 °C

“…Researchers have carried out systematic research on the flexible thermocouple temperature sensor [12][13][14][15][16][17][18], which is mainly composed of two parts, a temperature-sensitive layer made of two different materials and a flexible substrate. The temperature-sensitive layer is mainly made of metals [11,12,14,16,18], metal compounds [2,[13][14][15] and nonmetallic compounds [17], and the flexible substrate of Polydimethylsiloxane (PDMS) [18], polyimide [2,[12][13][14][15] and other polymer materials [16,17]. However, not only the [2,12,13,15,16,18].…”

Conformal Cu–CuNi Thermocouple Using Particle-Free Ink Materials

“…Electronic devices are quickly progressing toward lightweight and compact whilst also being flexible . One device of interest is the temperature sensor, which includes the likes of resistance temperature detectors (RTDs), − thermistors, − semiconductor-based integrated circuits, and thermocouples. − In this context, thermocouples have been of interest due to a variety of material selections − although traditional thermocouples would be made of bulk metals. Thermocouples function on the Seebeck effect, a phenomenon which causes a small thermoelectric current to be produced when the junction consisting of two different metallic materials in contact is subjected to varying temperatures.…”
