Large‐Scale Smart Carpet for Self‐Powered Fall Detection

Abstract

solitude and the first time to help patients are becoming increasingly important and exigent. Fortunately, the development of science and technology has made this urgent demand no longer out of reach. [5] Over the past few decades, three mainstream fall monitoring methods have been developed, including vision-based, [6,7] ambient-based technologies, [8,9] and wearable-based, [10][11][12] according to the type and position of sensors that are installed in the systems. However, in the course of use, these methods

Natural silk-composite enabled versatile robust triboelectric nanogenerators for smart applications

“…[6,9] However, Triboelectric Nanogenerators (TENGs) have gained an enormous interest owing to their high conversion efficiency of ambient mechanical energies into electricity, facile and cost-effective fabrication techniques, and the great potential to be utilized as self-powered wearable sensors in health monitoring, biosensors, human-machine interactions, and other fields. [10][11][12][13][14][15][16] TENGs, first reported by Z.L. Wang's group in 2012, [17] convert various ambient mechanical resources into electricity based on two fundamental principles; contact electrification and electrostatic induction.…”

Elastic Kernmantle E‐Braids for High‐Impact Sports Monitoring

“…Fabrication of Core-Spun Yarns and Electronic Braids: The core-spun yarns were obtained through a commercial high-speed spinning frame and the detailed fabrication process has been described in the authors' previous work. [40,48] Using the core-spun yarn obtained above as the basic unit and high-elastic silicone as the core, large-scale electronic braids can be obtained through commercial braiding machines.…”

Fibrous triboelectric nanogenerators: fabrication, integration, and application

“…Yarn spinning is the process of making multiple monolaments into yarn or thread, [127][128][129] which is benecial for the massproduction of compound yarns due to its mature and mechanized process. 30,64,66,97,130 Therefore, the application of yarn spinning in the fabrication of TENGs provides a big opportunity for the industrial production of F-TENGs. 131 Through the suitable design of the core lament and sheath bers, the structure and properties of F-TENGs can be optimized.…”
