DOI: 10.1002/aenm.201602096 of highly conductive fillers (>107 S m−1, silver nanowires and carbon nanomaterials) into an elastomeric matrix.[23] Unlike deterministic composite, these devices are intrinsically stretchable as fillers maintain electrical contact by sliding along each other during stretching.[22] Intrinsically stretchable batteries have been reported, but none are completely elasti...
