Electrostatic Jet Engineering of Flexible Composite Pressure Sensors for Physical Applications

Design and fabrication of highly sensitive flexible sensors is an area intense interest research but limited with respect to the detection range application (e.g., deployment in both terrestrial aquatic environments). Here, we present pressure (FPSs) comprising graphene–PANI-embedded polyethylene oxide exhibiting ultralow limits. These were prepared using a modified electrohydrodynamic (EHD) jetting method enabled wearable monitoring physiological parameters selective life activity. Sensor thickness, resistance, sensitivity modulated through jetted layers. Through EHD jetting, minimum detected static was seen be 12 Pa. The strain resistance test displayed gauge factor 5.5 under bending 12.5–50%. FPS engineering performed green, sustainable, cost-effective approach demonstrated high sensitivity, limits, rapid response, excellent mechanical durability. Detection minute signals during physical activity finger movements, facial expression, cough, hand gestures, acoustic vibrations, real-time pulse waves near-body states) shown. Furthermore, underwater elucidates potential emerging healthcare, environmental, bio-related monitoring.
