Tough, antibacterial and self-healing ionic liquid/multiwalled carbon nanotube hydrogels as elements to produce flexible strain sensors for monitoring human motion

Carbon Nanotubes and Silica@polyaniline Core–Shell Particles Synergistically Enhance the Toughness and Electrical Conductivity in Hydrophobic Associated Hydrogels

“…As a result, when too much is added, the excess carbon nanotubes can interact and build up in the various conductive channels of the polymeric network, piercing the polymeric network and preventing the transmission of some electrical signals. Not only that, but this stacking behavior also weakens the nonconjugated relationship between C-MWCNT and SiO 2 @PANI core–shell particles and polymer segments, thus blocking the original conductive pathways and leading to a decrease in electrical conductivity. − Therefore, we infer that the addition of C-MWCNTs, the degree of dispersion, and their interaction with SiO 2 @PANI-P­(AM/LMA) are combined factors that determine the conductivity trend.…”

Phytic acid/tannic acid reinforced hydrogels with ultra-high strength for human motion monitoring and arrays

“…Under applied stress, the hydrogel distributes tension through the sliding of PVA molecular chains and a multitude of reversible hydrogen bonds between or within molecules. 42 When the tension is released, the broken hydrogen bonds rapidly reform, resulting in macroscopic recovery of the hydrogel. In Fig.…”

Multifunctional small biomolecules as key building blocks in the development of hydrogel-based strain sensors

“…Hydrogels have attracted attention as strain sensors in human health and physiological signal monitoring, 59,60 soft robotics, 61,62 and human–machine interfaces. 63–65 Hydrogel strain sensors have recently been applied as wearable sensors in wrist pulse or heart rhythm monitors, 66,67 visual sensors, 68,69 and human interaction 70 and motion monitors.…”
