The development of wearable electronic devices has created a better blueprint for future human computer interaction and intelligent living. Flexible pressure sensor is an important link to the development of wearable electronic devices. Despite significant progress made to date, there are still issues to be solved, including complex material synthesis, cumbersome preparation process and poor sensitivity response to human body signal. In this paper, we report flexible sensors that could be applied in different conditions. The sensors are fabricated by combination electrospinning-prepared PVDF nanofiber film with PDMS/Ag NWs and PET/ITO electrodes, respectively. The sensors based on PVDF nanofiber film feature good piezoelectric property with quantitative pressure measurement. Furthermore, they can act as a real-time monitor of human movement due to their conformal form factors. In addition, the sensors realize non-direct contact sensing, providing a broad design idea for future non-contact human-computer interaction. Our approach provides a new, simple, and cost-effective strategy for the development of wearable pressure sensors. (C) 2018 Elsevier B.V. All rights reserved.
