Conductive reduced graphene oxide (rGO) patterns have been successfully fabricated on graphene oxide films coated on polydimethylsiloxane (PDMS) substrate via femtosecond laser direct writing (FsLDW)-induced photoreduction. Through this mask-less and high-resolution technique, the electrical conductivity of rGO patterns can be tuned by simply adjusting the laser writing parameters. Noticeably, based on FsLDW, high-performance and stretchable graphene-based strain sensors were fabricated and can be utilized for monitoring of human motion and respiration, heartbeat detection, and human/machine interaction.
