Piezoresistive force sensors based on interparticle quantum tunneling among electroactive fillers are widely used in various fields of wearable healthcare device, and human-machine interaction, touch panel, and energy harvesting due to its enormous potentials enabling to realize integrated sensing system. So far, however, existing strategies to form percolative networks have shown poor sensitivity in low pressure range despite use as a promising candidate for the stimuli sensing layer. To improve the sensing performance, in this study, we demonstrate synergistically combined spike-stimulated dendritic network leading to the significantly enhanced quantum tunneling effect among fractal conducting microchannels. Fabricated nanocomposite sensor shows standout capability to transduce the dynamic pressure distributions from external stimuli into electrical signal variations enabling to detect soft touch on the human skin and display touch panel.
