About the Cover:

We report a highly skin-adaptive, sweat-drainable patch with an isotropically stretchable and durable nanotube-implanted electrode via a selective-transfer technique for multiplexed bioelectronics. Inspired by the wrinkled suction cups in the forelegs of diving beetles, the water-repellent adhesive patch can stably monitor multiple biosignals (electrocardiography and skin temperature) without delamination on skin in sweaty and even harsh dynamic conditions.
