Flexible pressure sensors based on polymer elastomers filled with conductive fillers show great advantages in their applications in flexible electronic devices. However, integratable high-sensitivity pressure sensors remain understudied. This work improves the conductivity and sensitivity of PDMS-Fe/Ni piezoresistive composites by introducing silver flakes and magnetic-assisted alignment techniques. As secondary fillers, silver flakes with high aspect ratios enhance the conductive percolation network in composites. Meanwhile, a magnetic field aligns ferromagnetic particles to further improve t...

Conductive elastic composites composed of conductive fillers and polymer matrices are showing an increasing number of applications in the fields of flexible sensors, wearable devices, and stretchable electronics. Under mechanical deformation, the conductive filler network in the matrix shifts to change the conductive pathway among particles and thus, electrical conductivity of the composite. For most conductive composites, their conductivity changes monotonically with strain. Here, we report a composite that exhibits an unconventional strain response; its electrical conductivity increases shar...
