Abstract Electrorheological fluids (ERF) have garnered significant attention for their potential to provide actuation on demand. Similarly, developing stimuli‐responsive printable inks flexible electronics is also gaining antecedence. However, a material that demonstrates both functionalities far and few. Accordingly, ink made using silylated carbon nanofiber (SiCNF)‐polydimethylsiloxane (PDMS). The viscosity of the increased by 43%, when subjected an electric field ( E ). Robust stability 20 cycles under = 300 V mm −1 noted. yield stress (τ y ) value 1600% 600 compared zero‐field stress. Applying temperature with further τ . In absence E, applying not only slowed down relaxation modulus but counterintuitively augmented extent sluggishness increase in temperature. A comprehensive study waiting time indicated structure build‐up within composition happening as increases. time‐temperature time‐waiting superposition principle applied predict long‐term behavior inks. Further, printability index check studied used printing designs direct writing. printed demonstrated pressure sensing capability sensitivity 6.3%/kPa stable over 60 cycles.
