摘　　要：Bulky external power supplies largely limit the continuous long-term application and miniaturization development of smart sensing devices.Here,we fabricate a flexible and wearable integrated sensing system on an electrospun all-nanofiber platform.The three parts of the sensing system are all obtained by a facile ink-based direct writing method.The resistive pressure sensor is realized by decorating MXene sheets on TPU nanofiber.And,the resistive temperature sensor is prepared by compositing MXene sheets into poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:PSS).The thin-film zinc–air battery(ZAB)includes an interdigital zinc–air electrode that is bonded with a gel polymer electrolyte.It can supply a high open-circuit voltage of 1.39 V and a large areal capacity of 18.2 mAh cm^(-2) for stable and reliable power-supplying sensing parts operation.Thanks to the hydrophobic nature of TPU and open-ended micropores in the TPU nanofiber,the sensing system is waterproof,self-cleaning,and air and moisture permeable.For application,the above-mentioned functional components are seamlessly integrated into an intelligent electronic wristband,which is comfortably worn on a human wrist to monitor pulse and body temperature in real time with continuous operation of up to 4 h.By the novel design and remarkable performance,the proposed integrated all-nanofiber sensing system presents a promising solution for developing advanced multifunctional wearable electronics.
