In
recent years, wearable and flexible sensors have attracted considerable
research interest and effort owing to their broad application prospects
in wearable devices, robotics, health monitoring, and so on. High-sensitivity
and low-cost pressure sensors are the primary requirement in practical
application. Herein, a convenient and low-cost process to fabricate
a bionic fish-scale structure poly(dimethylsiloxane) (PDMS) film via
air/water interfacial formation technique is presented. High-sensitivity
flexible pressure sensors can be constructed by assembling conductive
films of graphene nanosheets into a microstructured film. Thanks to
the unique fish-scale structures of PDMS films, the prepared pressure
sensor shows excellent performance with high sensitivity (−70.86%
kPa<sup>–1</sup>). In addition, our pressure sensors can detect
weak signals, such as wrist pulses, respiration, and voice vibrations.
Moreover, the whole process of pressure sensor preparation is cost-effective,
eco-friendly, and controllable. The results indicate that the prepared
pressure sensor has a profitable and efficient advantage in future
applications for monitoring human physiological signals and sensing
subtle touch, which may broaden its potential applications in wearable
devices.
