This work presents a novel flexible tactile sensor array fabricated with PEDOT:PSS conductive polymer modified micro-structured polydimethylsiloxane (PDMS) bumps. PDMS bump arrays with micro-structures are coated with PEDOT:PSS conductive polymer for resistive tactile sensing. The micro-structures on PDMS bumps are produced by replicating the formed thermal bubble cavities during laser ablation of...
