Towards Application of Microscale Structural Superlubricity

Structural superlubricity (SSL), a state of near-zero friction and no wear between contacting solid surfaces, offers a disruptive approach to minimizing friction and wear. Recent years have seen a surge in SSL research, expanding its focus from fundamental science to practical applications, where the realization of robust microscale SSL play a key role. This chapter summarizes the recent advancements in SSL, with a particular emphasis on aspects that promote practical applications. These include SSL electrical contacts, SSL-based generators, the stability of SSL systems, and the environmental impact of SSL.
