Highly Sensitive and Stretchable Strain Sensors Based on Conductive Elastomer Composites.

ABSTRACT: Flexible strain sensors are essential for applications in surgical robots, wearable electronics, and soft electronic skin. However, it remains challenging to realize materials that combine both high sensitivity and large stretchability. The gauge factor (GF), which quantifies resistance changes under strain, is often low in highly stretchable polymers, because their conductive pathways remain intact during deformation. Here, we present conductive elastomer composites that integrate movable cross-links with carbon-based conductive fillers to overcome this trade-off. Among the four designed systems, γ-cyclodextrin-containing P₁-CD⊃P₂/KB achieved the best balance between mechanical and electrical performance. Systematic optimization of molecular weight, γ-cyclodex
