The development of flexible and stretchable electronic skins that can mimic the complex characteristics natural skin is great value for applications in human motion detection, healthcare, speech recognition, robotics. In this work, we propose an efficient low-cost fabrication strategy to construct a highly sensitive enables detection dynamic static pressure, strain, flexion based on elastic graphene oxide (GO)-doped polyurethane (PU) nanofiber membrane with ultrathin conductive poly(3,4-ethylenedioxythiophene) (PEDOT) coating layer. three-dimensional porous GO-doped PU@PEDOT composite nanofibrous substrate continuous self-assembled pathway nanofiber-based offer more contact sites, larger deformation space, reversible capacity pressure strain sensing, which provide multimodal mechanical sensing capabilities high sensitivity wide range. sensor demonstrates (up 20.6 kPa–1), broad range (1 Pa 20 kPa), excellent cycling stability repeatability (over 10,000 cycles), over approximately 550%). We confirmed applicability pulse monitoring, expression, voice full motion, demonstrating its potential use wearable human-health monitoring systems.
