FABRICATION OF ROLLED AND HOLLOW FIBRE DIELECTRIC ACTUATORS
Bibliographic record
Abstract
Dielectric polymer actuators normally operate at electric fields close to the dielectric breakdown strength of elastomeric materials, or in the range 30 ‐ 100 MV/m. The high electric fields required for dielectric actuator operation necessitate th e use of thin elastomeric films in their fabrication. In a recently completed Technology Investment Fund project, DRDC Atlantic and Bodycote Materials Testing Canada investigated various methods for producing dielectric actuators from thin polymeric films. During this study, methods were developed for the fabrication of rolled actuators using spray-casting, and fi bre actuators using melt processing. Spray-casting was carried out with a thermosetting polyether polyurethane formulation or a silicone elastomer, using a custom built apparatus for producing large area multi-layer films. Fibre actuators were fabricated from thermoplastic polyurethane using a co-extrusion process to produce hollow tubes with internal and external compliant electrodes. The most difficult challenges encountered were related to electrical termination of the compliant electrodes, and dielectric film conductivity. Results of this study are discu ssed along with performance data for rolled and fibre actuators.

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.
