Human health and food safety are global challenges, seriously endangering the sustainable development of human and society. Owing to high sensitivity and excellent mechanical properties, traditional film-based wireless sensor devices can capture human physiological signals, but it is hard to make a breakthrough in simultaneousreal-time monitoring of food spoilage. Concretely, due to difficult-to-control molecular behavior and the conflict between rapid solidification and order structure, the fabrication of film-based sensor device with orderly conductive pathways remains a great obstacle. Herein, a scale-producible room-temperature water-driven strategy is employed to manufacture pomegranate-structured film-based sensor devices with fast-solidified orderly conductive pathways for simultaneous detecting human physiology and spoilage gas signals by assembling multi-branched cellulose nanofiber (MCNF), polyaniline (PANI) and multi-walled carbon nanotube (CNT) via multiple bonds. Surprisingly, the superhigh sensitive sensor devices can be successfully integrated into awireless heart rate monitor and smart packaging monitoring system for real-time monitoring human physiological and food spoilage gas signals. Therefore, this strategy enables molecular ordering by room-temperature.water-driving, which resolves the conflict between fast solidification and ordered structure and provides a new paradigm to address health management and food packaging issues.
