Abstract

Abstract : A self-energy monitoring system was developed that exhibited excellent electrochemical performance and rapid temperature response. Abstract : The fast development of wearable and portable smart electronics has immensely encouraged the demand for miniaturized integrated electronic devices. In this study, we utilized a duplex printing strategy to construct an all-in-one integrated electronic device by integrating asymmetric micro-supercapacitors (MSCs) with a tandem line-type temperature sensor (TLTS) based on reduced graphene oxide (rGO). In the integrated configuration, the 3D printing asymmetric MSCs based on MXenes/single-walled carbon nanotubes (SWCNTs) positive electrode and rGO/SWCNTs negative electrode delivered a large areal specific capacitance of 30.76 mF cm −2, high energy density of 8.37 μW h cm −2, and long lifetime (no significant capacitance decay of over 10 000 cycles). Moreover, the assembled device can offer the stable out power to TLTSs. Particularly, the temperature sensitivity of the duplex printed integrated electronic device can reach 1.2% per degree celsius. Collectively, the efficient 3D printing strategy can be used to build diverse all-in-one integrated electronic devices with state-of-the-art performance for next-generation wearable and portable electronics.
