Electrohydrodynamic printing of silver nanowires for flexible and stretchable electronics

High-resolution, large-scale printing of highly conductive AgNWs for flexible and stretchable electronics using EHD printing is presented. The printed patterns show the smallest line width of 45 μm and electrical conductivity as high as ∼5.6 × 10⁶S m⁻¹. AgNW-based wearable heaters and ECG electrodes are fabricated.
