Facile monitoring for human motion on fireground by using MiEs-TENG sensor

Object recognition by a heat-resistant core-sheath triboelectric nanogenerator sensor

“…1 In addition, in order to simplify the operation and improve accuracy, statistical features such as the amplitude, mean, and standard deviation of the data can be extracted for subsequent analysis. 26 Finally, the transformed data were stored on a computer and handled by the SVM classifier. Specifically, these multi-dimensional features will define the identity of the captured object.…”

“…25 According to available literature, aramid fibers and silicon rubbers are good positive layers and negative layers, respectively. 26 Nevertheless, the assembly of gel, fibers, and rubbers with different phases to form an integrated TENG sensor with high stability and flexibility is still a challenge. In addition, the data signal output is large during sensor operation, and the efficiency of human accurate analysis of the original signal is poor.…”

Human body IoT systems based on the triboelectrification effect: energy harvesting, sensing, interfacing and communication

“…5d, Sun et al presented a novel TENG-based sensor for human motion monitoring on fireground by employing designed patterned MXene ink electrodes printed directly onto the triboelectric materials. 136 A TENG with a rectangular electrode was attached to the elbow to sense the bending of the joint by sensing simple emergency hand signals. By using the double needle bed flat knitting machine technology, Chen et al fabricated a 3D double faced interlock fabric TENG that was implemented as a stretchable wearable TENG-based sensor to monitor the bending of the arm joint (Fig.…”

Wearable Electronics Powered by Triboelectrification between Hair and Cloth for Monitoring Body Motions

“…Energy challenges and wearable electronic devices are gaining more and more attention in recent years, and there is a lot of room for research on obtaining energy from human motion and implementing sensing functions. [1][2][3][4][5][6][7] Inspired by the triboelectric effect between clothes during human movement, many studies have achieved energy conversion and biosensing by integrating triboelectric nanogenerators (TENGs) into the fabrics that humans wear or by attaching TENG units to human bodies. [8][9][10][11][12][13][14] However, the materials used in the majority of studies were not only complex but also expensive.…”
