A highly stretchable and intrinsically self-healing strain sensor produced by 3D printing

One common issue when implementing wearable strain sensors for health-monitoring is the limited service time when they are inevitably subjected to mechanical operation in practical applications. Therefore, integrating multi-functionality with reliable performance is a long-term pursing target. To this end, we have developed a promising strain sensor utilising a facile 3D printing technology of digital light processing (DLP), thereby...
