主　　题：3D printing conducting polymer hydrogel flexible sensor micro-wrinkle structure 

摘      要：Conducting polymer hydrogel can address the challenges of stricken biocompatibility and ***,conventional conducting polymer hydrogels are often brittle and weak due to the intrinsic quality of the material,which exhibits *** property may cause a delay in sensor response time due to *** overcome these limitations,we have designed a wrinkle morphology three-dimensional(3D)substrate using digital light processing technology and then followed by in situ polymerization to form interpenetrating polymer network *** novel design results in a wrinkle morphology conducting polymer hydrogel elastomer with high precision and geometric freedom,as the size of the wrinkles can be controlled by adjusting the treating *** wrinkle morphology on the conducting polymer hydrogel effectively reduces its viscoelasticity,leading to samples with quick response time,low hysteresis,stable cyclic performance,and remarkable resistance ***,the 3D gradient structure augmented the sensor s sensitivity under minimal stress while exhibiting consistent sensing *** properties indicate the potential of the conducting polymer hydrogel as a flexible sensor.
