In article number 2000177, Zhizhu He and co‐workers report a super‐stretchable (800%) liquid metal foamed elastomer composite, and yet achieve super‐high electrical (≈10 4 S cm −1 ) and thermal (17.6 W mK −1 ) conductivities under a large strain of 400%, which also exhibits unexpected stretchingenhanced electromagnetic‐interference shielding effectiveness of 85 dB due to the conductive network elongation and reorientation.
