Ultralight Biomass-Derived Carbonaceous Nanofibrous Aerogels with Superelasticity and High Pressure-Sensitivity.

Superelastic and pressure-sensitive carbonaceous nanofibrous aerogels with a honeycomb-like structure are fabricated through the combination of sustainable konjac glucomannan biomass and flexible SiO2 nanofibers. The aerogels can detect dynamic pressure with a wide pressure range and high sensitivity, which enables real pressure signals, such as human blood pulses, to be monitored in real time and in situ.
