Micro-/nanofiber-coupled superhydrophobic and conductive textile for underwater wearable strain sensors with full-scale human motion detection ability

Abstract

The as-prepared SNWTC exhibits excellent water super-repellency behavior under the initial and tensile states, realizing sensing service unaffected by water-based liquids in the air, and even working underwater for diving enthusiasts.

Pursuing Superhydrophobic Flexible Strain Sensors: From Design to Applications

“…[ 97 ] Different bending angles and frequencies are matched with Morse code “dots” and “dashes,” thereby establishing an underwater communication technology. The same approach was applied in another study ( Figure a), [ 162 ] further confirming the viability of superhydrophobic sensors for underwater communication applications.…”

Advancing coatings with polybenzoxazines: insights into molecular design, synthesis, and modification

“…Shakila Parveen Asrafali et al utilized a benzoxazine monomer, bis(6-phenyl diazenyl-3-phenoxy-3,4-dihydro-2 H -1,3-benzoxazinyl)benzonitrile (PBZ-BN), as a low surface energy material. They incorporated TiO 2 nanoparticles to enhance hydrophobicity, as the air trapped in the rough surface's gaps 90 blocks water from penetrating the nanoparticles, thereby increasing the contact angle with water. The resulting superhydrophobic PBZ-BN/TiO 2 composite displayed a substantial increase in WCA (146°) even at extremely low TiO 2 loading (∼5 wt%).…”

Flexible Mechanical Sensors Fabricated with Graphene Oxide-Coated Commercial Silk

“…Cotton fabric has been decorated with Ag nanowires, Ag flowers, and Ag thread [ 17 , 18 , 19 , 20 ]; coatings of electrochemically exfoliated graphene film have been applied on cotton fabric [ 21 ]; and coatings of Ag have been applied to cotton yarn using Ag paste followed by sintering [ 22 ] to provide electrical conductivity. Likewise, electronic textiles for sensors fabricated with nylon and polyester have been created using conductive polymers [ 23 ], Au and MoS 2 coating [ 24 ], graphite-polyurethane (PU) coating applied to crochet knitted elastic [ 25 ], the screen printing of elastic conductive carbon ink on polyester fabric [ 26 ], the wet spinning of CNT/thermoplastic PU on silver-plated nylon electrodes [ 27 ], the coating of CNT/carbon black PU on fabric with Ag-coated conductive nylon fiber [ 28 ], and the spraying of multiwall CNT/TiO 2 conductive suspensions on nylon textiles [ 29 ]. Mxene has also been applied to textiles to improve sensitivity [ 30 , 31 , 32 , 33 , 34 ].…”
