AbstractTo obtain flexible electronic materials with energy storage and sensing properties， β -cyclodextrin/polyacrylamide/polypyrrole （ β -CD/PAM/PPy） conductive hydrogel was prepared by insitu polymerization，and the mechanical，electrochemical and sensing properties of the hydrogels were investigated. The results show that the β -CD/PAM/PPy conductive hydrogel possess more than 300% elongation at break. The flexible supercapacitor assembled from the conductive hydrogel possess the largest area specific capacitance （ 26.158mF/cm2 ）with 0.04mmol （2 β -CD and

0.48mol/L pyrrole. Meanwhile the capacity retention rate is up to 86% after1 50o charging-discharging cycles and 83.2% after 3Oo times of bending. Moreover，the flexible sensor based on β⋅ 1 CD/PAM/PPy conductive hydrogel is able to detect human body motion which can be applied in energy storage and sensors.
