Abstract

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.

Keywords: biomass; carbonaceous aerogels; nanofibers; pressure sensors; superelastic.
