Wearable, fast-healing, and self-adhesive multifunctional photoactive hydrogel for strain and temperature sensing

Abstract

A wearable, fast-healing, and self-adhesive hydrogel is prepared to realize the monitoring of full-range human motion and give an impressive thermal response in human body temperature detection for health information collection, as well as tunable photothermal property.

Wearable, Biodegradable, and Antibacterial Multifunctional Ti3C2Tx MXene/Cellulose Paper for Electromagnetic Interference Shielding and Passive and Active Dual-Thermal Management

“…40 As shown in Figure 5a Considering the practical application in disease treatment such as arthritis and muscle injury, photothermal therapy with a stable and controllable output is required. 41,42 Therefore, the photothermal performance of the flexible Ti 3 C 2 T x /CNF heater exposed to a NIR (λ = 980 nm) laser with a certain distance of ∼5 cm from the light source is investigated (Figure 6a). Similar to the phenomenon under sunlight, the temperature of the Ti 3 C 2 T x /CNF paper can be elevated to ∼71.5 °C under NIR laser irradiation (200 mW/cm 2 ), which can also be simply controlled by tuning the power density (Figure 6b,c, Figure S7), demonstrating a controllable photothermal performance at different application scenarios.…”

PSS-dispersed dopamine triggered formation of PAA adhesive hydrogel as flexible wearable sensors

“…1–3 Recently, inspired by natural mussel adhesion, various catechol-based adhesive hydrogels have been proposed in the synthesis of self-adhesive epidermal sensors. 4–6…”

“…[1][2][3] Recently, inspired by natural mussel adhesion, various catechol-based adhesive hydrogels have been proposed in the synthesis of self-adhesive epidermal sensors. [4][5][6] So far, several catechol-based adhesive hydrogels have been fabricated using catechol-containing polymers, catecholfunctionalized monomers, and other catechol-functionalized materials. [4][5][6][7][8][9][10][11][12][13][14] Dopamine (DA), an important neurotransmitter found in the brain, contains both catechol and amine groups.…”

Tri-cationic copolymer hydrogels with adjustable adhesion and antibacterial properties for flexible wearable sensors

“…Another is the internal self-adhesion such as biomimetic adhesion chemistry. By introducing adhesion monomers such as dopamine, 13,14 phenolic hydroxyl compounds 15,16 and nucleic acid bases 17,18 into the target material, the self-adhesion behaviours of the material are realized. This method could avoid the discomfort and inconvenience caused by the external auxiliary method, and is becoming the mainstream method today.…”
