AgNW/Graphene Hybrid Electrode for Dielectric Elastomer Actuator
Bibliographic record
Abstract
Dielectric elastomer actuators (DEAs) necessitate stretchable electrodes that show mechanical compliance and sustain conductivity even under stretching. A percolative network of silver nanowires (AgNWs) as an ultrathin film formed on the elastomer meets all these requirements as stretchable electrodes. However, AgNWs are prone to thermal degradation due to resistive heating caused by applied electrical current. This work introduces a hybrid stretchable electrode of AgNWs coated by graphene nanoplatelets (GNPs) to produce more resilient and durable DEAs. GNPs added to preformed AgNW structures act as a protective layer, mitigating localized heating at NW junctions and eventually preventing DEA failure. The hybrid electrodes show a sheet resistance as low as 9 Ω/sq and electromechanical strain as high as 56.5% at an electric field of 45 V/μm when integrated into the DEAs. The AgNW/GNP DEAs also show high endurance, withstanding an applied electric field up to 70 V/μm without failure. This work showcases the advantages of rationally selected hybrid materials that produce more resilient DEAs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
