Abstract By virtue of the excellent flexibility, conformability, portability, and aesthetics, wearable photodetectors have attracted worldwide research enthusiasm over past decade. However, traditional bulk covalent semiconductors are difficult to be applied due their pronounced rigidity. Profiting from self‐passivated surface, carrier mobility, strong light‐harvesting ability, low‐dimensional van der Waals materials (LDvdWMs) shown immense potential for application in optoelectronic devices.
