Ultra-fast self-healable stretchable bio-based elastomer/graphene ink using fluid dynamics process for printed wearable sweat-monitoring sensor

Anti‐Fouling Polymer or Peptide‐Modified Electrochemical Biosensors for Improved Biosensing in Complex Media

“…[188] Son et al created a selfhealable and conductive ink by incorporating graphene into the self-healing polymer poly(1,4-cyclohexanedimethanol succinateco-citrate), with the printed serpentine-structured electrode exhibiting good conductivity while spontaneously healing during 10 cut-heal cycles with a healing time of just 12 s at ambient conditions while retaining a sensitivity of 99% for detecting Na + in sweat in real time. [189] The incorporation of antifouling hydrogels within these of similar self-healing coatings thus offers potential, particularly in designing wearable and implantable sensors with enhanced performance. A) A self-healing anti-biofouling complex hydrogel composed of gold nanoparticle (AuNPs), molybdenum disulfide (MoS 2 ) and polypeptide integrated into an electrochemical sensor for continuous monitoring of uric acid and ascorbic acid levels in sweat.…”

Smart healable polyurethanes: sustainable problem solvers based on constitutional dynamic chemistry

“…24 Based on their functional features, healable PU elastomers hold great promise for soft electronics. As far as we know, a typical approach developed to fabricate healable electronics involves embedding a network of conductive fillers, such as liquid metal, 127,128 ionic liquid, 129,130 graphene, 131 MXene, 132 metal-based nanowire, 133,134 carbon nanotubes, 135 etc. into a healable PU elastomer.…”

Advanced Self-Powered Biofuel Cells with Capacitor and Nanogenerator for Biomarker Sensing

“…Mechanical resilience of BFC sensors can be improved by incorporating stretchable electrode inks prepared by mixing soft elastic binders along with conductive filters wherein high performance can be restored in the stretched state with a strain of up to >100%. 143 A corresponding material ink when printed on a flexible textile substrate exhibits a minimum resistance change under high tensile strength 200% for a longer cycle. A microstructure offers high compressibility and stretchability that stem from the nanomicro-macro trans-scale design of three-dimensional structure with tunable electrical conductivity and tuned resistivity such as cellulose nanofiber paper (CNP) with stretchable electronics on a paper substrate.…”
