Fabrication of graphene-based stretchable strain sensors using femtosecond laser direct writing

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 cond...

Description
Summary: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.
