“…A wireless sensor network (WSN) can be defined as a network composed of sensor nodes, which are distributed in the network deployment area and work together. The information collected from the monitoring site is transmitted through the wireless link [13]. The data collected by the sensor nodes are sent to the base station, which can process the data locally, or further transmit the data to other data storage or processing centers through the network.…”

Running exercise can increase the basal metabolic rate and increase the time of aerobic exercise. It is a healthy and effective exercise method. Based on the current needs of the general public for running auxiliary training, this article combines wireless sensing and blockchain technology in the design scheme, and designs and implements a running training auxiliary technology. First, obtain the user's gait information and other related parameters in the process through the wireless sensor network, and optimize the calculation gait in different states through the noise processing algorithm. Then, use the blockchain technology to design a data transmission and storage plan for the protection and analysis of the user's personal privacy data. This technology builds a new type of sports training assistance system for the masses of modern society and contributes to the masses' physical exercise.

“…The commonly used wireless temperature sensing systems (temperature sensors) include surface acoustic waves (SAW), microwave wireless temperature sensors, and inductance and capacitance (LC) [ 26 , 27 , 28 , 29 , 30 ]. The temperature sensor based on the resonant inductance capacitance (LC) circuit did not require a power supply or physical lead connection [ 31 , 32 ]. Because of the small size and stability of LC sensors, they are especially suitable for short-distance transmission tests in harsh industrial environments.…”

As the key component of aero-engines and industrial gas turbines, a bearing’s working temperature at high speed is close to 300 ℃. The measurement of an engine bearing’s temperature is of great significance to ensure flight safety. In this study, we present a wireless LC conformal temperature sensor for bearing temperatures, which integrates silver on the bearing surface in situ through a screen-printing process. This process makes Ag film (9912-K FL) firmly adhere to the bearing surface and realizes wireless measurements for bearing temperatures in situ. A high-temperature holding experiment of the prepared sensor was conducted, and the results showed that the sensor can work stably for 10 h at 300 ℃. We tested the designed wireless LC conformal temperature sensor at 20–270 ℃. The results showed that the proposed temperature sensor attained as good accuracy and stability in the temperature range 20–270 ℃. The sensitivity of the temperature measurements was 20.81 KHz/℃ when the bearing rotateds, the maximum repeatability was 0.039%, the maximum uncertainty was 0.081%, and the relative error was stable within 0.08%.

“…However, the operating temperatures of these sensors generally do not exceed 500°C, imposing significant limitations when operating in higher temperature environments ( Naderi and Moghaddam, 2020 ; Salvatori et al, 2020 ; Abdel-Motaleb and Dittakavi, 2021 ). Most LC-type high temperature pressure sensors are fabricated using either a low-temperature co-fired ceramic (LTCC) or high-temperature co-fired ceramic (HTCC) technology ( Lin et al, 2018 ; Zhu et al, 2018 ; Raynaud et al, 2021 ; Zhang et al, 2021 ; Seek and Makarovi, 2022 ). In these methods, sensors are using combined processes of multilayer ceramics and laminations, high-temperature sintering, and screen-printing processes, however, the manufacturing process is complex.…”

The process method of a Si3N4 ceramic sealed cavity is realized by vacuum brazing and chemical reaction at 1,100°C and 0.5 MPa pressure. Through the combination of Si3N4 ceramic polishing and thinning, inductively coupled plasma etching, and high-temperature metal filler (Ti-Zr-Cu-Ni) brazing process, a vacuum-sealed cavity suitable for high-temperature environments was prepared. The cross section of the bonding interface was characterized by scanning electron microscope (SEM) and energy dispersive spectrometer (EDS), which indicated that the two Si3N4 ceramic were well bonded, the cavity structure remained intact, and the bonding interface strength exceeded 5.13 MPa. Furthermore, it retained its strong bonding strength after in high-temperature environments of 1,000, 1,050, and 1,100°C for 1 h. This indicates that a brazed vacuum-sealed cavity can be used in high-temperature environments. Through the proposed method, pressure sensor that can withstand high temperatures can be developed.
