Thermoplastic polyamide elastomers (TPAEs) with 6 (PA6) as hard segments and polyether amine soft are successfully synthesized by one‐pot melt polycondensation, in which the tensile strength elongation‐at‐break of resulting TPAE segment content 43 wt% reached (27.54 ± 0.92) MPa (508.10 19.81)%, respectively. Subsequently, two different types chain extenders Joncryl ADR 4468 ((ADR)/Hexamethylene Diisocyanate (HDI) trimer) applied to enhance molecular entanglement TPAEs. It is found that showed a better extension effect, TPAEs improved significantly when 5 wt%, corresponding foam possessed outstanding compressive resilience stability. Based on excellent compression property, contact‐separated triboelectric nanogenerator assembled friction layer, demonstrated high open‐circuit voltage 20.4 V, short‐circuit current 0.74 μA, power density 0.18 W m −2 , durability. Overall, prepared foams provided an avenue for high‐performance self‐powered intelligent footwear materials.
