Silver nanowire net knitted anisotropic aerogel as an ultralight and sensitive physiological activity monitorElectronic supplementary information (ESI) available. See DOI: 10.1039/c8bm00651b

Inherent highly ordered anisotropic aerogels were prepared through a facile celery-carbonization process. The subsequent modification of silver nanowire knitted nets endowed the prepared carbonaceous aerogel with several valuable properties, including broad-spectrum antibacterial activity, near-infrared responsive heating, lightweight cushioning and anisotropic pressure-sensitive conductivity. With the aid of 3D printing technology, this versatile material could be applied as an ultralight monitor to realize the visualized detection of different physiological activities, such as ankle movements and cardiac arrhythmias.
