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 read more 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 simultaneously realising super-high stretchability and intrinsic self-healing ability.Owing to the incorporation of carboxyl multi-walled carbon nanotubes (c-CNTs), the over-curing of the N-acryloylmorpholine (ACMO) resin was read more adequately mitigated, and good electrical conductivity of the nanocomposite was obtained.

On the basis of multi-functionality, the strain sensor before and after self-healing can be applied for real-time and accurate detection of human activities.Therefore, it is expected that the highly stretchable and intrinsically self-healing strain sensor will have promising applications in wearable electronics, personal health care, etc.
