Over
the past decade, the demand for high-performance wearable sensors
has increased because of their capability for interaction with humans.
Such sensors have typically been prepared on conventional substrates,
such as silicon, PDMS, and copper mesh. In this work, we propose a
class of wearable sensors fabricated from reduced graphene oxide (rGO)
patterned paper substrates (rGO-paper). These rGO-paper sensors are
highly sensitive to various deformations and capable of measuring
bending and folding angles as small as 0.2° and 0.1°, respectively.
We have demonstrated the applicability of these high-performance rGO-paper
sensors by patterning rGO on kirigamis that can detect pulse and the
motion of knees, wrists, and fingers. Finally, paper rings lined with
rGO sensors were used to control a robotic hand, and an rGO-paper
keyboard was used to light LEDs.
