▎ 摘  要

We report a highly sensitive pressure sensor array fabricated with photothermally reduced graphene oxide (GO). Nonconductive GO thin film is converted into conductive (10(4) S/m) thin layer by fast and precisely designed laser scribing method to generate pressure sensors with sensitivity of 19 mV/kPa. The fabricated array is easily attachable on any surface for monitoring applied forces or pressure and maintains excellent electrical conductivity under high mechanical stress and thus holds promise for durable sensors.
