Multilayer Step-like Microstructured Flexible Pressure Sensing System Integrated with Patterned Electrochromic Display for Visual Detection

, a wide linear response range up to 35 kPa, as well as excellent durability (∼5000 cycles). The electrochromic display is designed as a common cathode structure patterned via DIW printing, which exhibits fast coloring time (<0.4 s) and long-term durability (>6000 s). This work successfully demonstrates pressure visualization in human finger bending recognition and weight measurement. Moreover, this system will enhance the visualizable pressure identification capabilities of robotic hands and prosthetics, thereby offering users a more intuitive and real-time interactive experience.
