ACS Applied Polymer Materials, Год журнала: 2024, Номер 6(14), С. 8548 - 8559

Опубликована: Июль 16, 2024

The use of hydrogel strain sensors in flexible electronic wearable devices has garnered significant attention. However, achieving hydrogels with comprehensive properties such as excellent tensile strength, strong adhesion, rapid self-healing, and high sensitivity simultaneously remains challenging. Herein, inspired by mussels, we developed a straightforward polymerization process an aqueous solution using the polymerizable monomer 3-methylacryloyldopamine, containing catechol structural unit, along acrylic acid, sodium acrylate, ethylene imine polymer, zwitterionic [2-(methacryloyloxy) ethyl] dimethyl-(3-sulfopropyl). This resulted double-network structure featuring multiple dynamic interactions. sensor exhibited remarkable (up to 4200%), adhesion (adhesion for wood: 3370 kPa), self-healing ability (3 s), (GF = 13.75), allowing accurate repeatable detection both large-scale subtle human movements. Furthermore, addition glycerol endowed capability functioning at low temperatures (−40 °C). Such adhesive dopamine-based also potential skins, dressing, human–machine interface.

A Flexible and Adhesive Strain Sensor Based on Deep Eutectic Solvents for Deep Learning-Assisted Signal Recognition

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Апрель 24, 2025

Flexible wearable electronic devices have garnered significant interest due to their inherent properties, serving as replacements for traditional rigid metal conductors in personal healthcare monitoring, human motion detection, and sensory skin applications. Here, we report a preparation strategy self-adhesive, ultrahigh stretchable DGel based on poly(acrylic acid) (PAA). The resulting exhibits high tensile strength (approximately 2.16 MPa) an stretchability 5622.14%). More importantly, these meticulously designed DES gels demonstrate signal recognition capabilities under strains ranging from 1 500%. also shows excellent cyclic stability durability (5000 cycles at 100% strain), exhibiting superior electromechanical performance strain sensor. of is attributed the synergistic effects chemical physical cross-linking within gel. Additionally, can be effortlessly assembled into sensors. By integration flexible sensing with deep learning, fabricated touch system achieves identification accuracy up 99.33%. This advancement offers new insights designing novel variety applications, including tissue engineering, sensing, devices.
