All‐solid‐state flexible supercapacitors based on strategically created three‐dimensional hierarchically porous graphite foams are reported by Donglei Fan and co‐workers in article number 1702738 . The supercapacitors exhibit ultrahigh specific capacitances based on the entire electrode weight and retain 80% of capacitance after 1000 continuous bending cycles. They can be seamlessly integrated with strain sensors for self‐powered detections of strains from skins, including carotid artery pulses and finger bending.
