Cracks are always associated with defects or damage. However, recently cracks have attracted great research interest in many fields. One of the most successful applications of cracks is nanocrack-based strain sensors (nCBSSs). The first nCBSS prototype developed in 2014 was bioinspired by the crack-shaped sensory organs of a spider, and it exhibited an incredible sensitivity to strain and vibration. From then on, a lot of effort has been devoted to studying nCBSSs, and nCBSSs have demonstrated their great potential for applications in just a few years. Herein, aiming to provide a valuable reference to researchers from different fields, a comprehensive review of nCBSSs is provided, including their typical fabrication processes, sensing mechanism, performance and applications particularly for personal healthcare, sport performance monitoring and human–machine interfaces. Finally, a brief conclusion and several current challenges were discussed.
