This study reports a highly sensitive silicon carbide nanoparticle-based relative humidity sensor fabricated via serigraphic printing. The active 3C-SiC layer and silver electrodes are printed directly onto thick flexible polyimide (Kapton®) substrates. The printed sensors are integrated into a commercial KN95 mask for monitoring respiration parameters, showing the potential for future exploration in human health monitoring, utilizing fully printed, low-cost sensing devices.
