Summary: A scalable wireless wear monitoring system has been designed and deployed in a distributed harsh industrial environment, where installation of electronic equipment near wearing measuring locations is not feasible. The system utilizes a novel LC-type passive wireless wear sensor system and a sensor readout coil, and employs a double Holt-Winters method for data analysis. Laboratory measurements and on-site operation demonstrate high precision and sensitivity of the system.

Summary: This paper presents flexible pressure sensors based on 3D printing technology, with a sandwich structure design and a hollow prism structure pressure sensitive layer. Experimental synthesis of three kinds of flexible composite dielectrics demonstrated that the sensor with PDMS doping both BaTiO3 and CNTs showed the highest sensitivity, 1.3 times that of the reference sensor, indicating that fabricating composite dielectrics in this way has the potential to improve device performance.

Summary: A high-precision fusion strategy is proposed for temperature monitoring in aquaculture ponds, which includes preprocessing the temperature data using an improved unscented Kalman filter, fusing the data collected from sensors at the local fusion center using sequential analysis and fast inverse covariance intersection (ICI) algorithm, and fusing the temperature data from the middle layer at the global fusion center using an improved seagull algorithm to optimize the extreme learning machine (ELM) algorithm. The results demonstrate that the fusion strategy reduces external interference, improves the accuracy of global optimal temperature state estimation, and ensures the stability and accuracy of data fusion.

Summary: Soft capacitive pressure sensors with high performance are in demand in the flexible wearable field. Resistive-capacitive hybrid response fiber pressure sensors (HFPSs) with three-layer core-sheath structures are proposed to overcome the limited sensitivity range of capacitive fiber pressure sensors. The hybrid response enhances the practical sensitivity of HFPSs, allowing them to effectively monitor pulse signals at preloads ranging from 0 to 22.7 kPa.

Summary: This study proposes a flexible capacitive pressure sensor based on filter paper substrate. The sensor utilizes an electric double layer (EDL) structure formed by introducing an ionic liquid (IL), and detects pressure through the change of ion-electron interface contact. With a high sensitivity of 221.9 kPa(-1) and an ultra-low detection limit of 2 Pa, this paper-based iontronic pressure sensor has enormous potential in healthcare wearable electronics and human-machine interface equipment.
