“…With the rapid development of intelligent electronic equipment, flexible electronic devices are urgently needed in many areas, including human health monitoring, , human–machine interface systems, , soft robotic systems, , electronic skins, , flexible displays, , and so on. Among them, the flexible piezoresistive-type pressure sensor develops rapidly, which can convert mechanical deformation into electrical signal variation. , Three-dimensional (3D) aerogel pressure sensors have attracted widespread attention because of their high porosity, low density, good chemical stability, good compression resilience, and rapid response to external stimuli. , There are various aerogels that have been researched, including graphene aerogels, , transition-metal carbides and/or nitride (MXene)-containing aerogels, , and biomass aerogels. , The ultralight biomass aerogels with the merits of low cost, degradability, and renewability can solve the problem of electronic waste production and environmental damage due to most polymers being difficult to degrade or recycle. − Biomass aerogels are promising materials for preparing green pressure sensors.…”
