Abstract

The invention discloses a preparation method of a self-powered electronic skin system based on a laser reduced graphene / MXene composite material. The preparation method comprises the following steps:S1, preparing a graphene oxide / MXene mixed solution; S2, uniformly coating a flexible substrate with the graphene oxide / MXene mixed solution prepared in the step S1 to obtain a high-density flexible graphene oxide / MXene composite film; S3, obtaining a patterned laser reduced graphene / MXene composite electrode from the high-density flexible graphene oxide / MXene composite film obtained in the step S2 by a laser direct writing technology. According to the technical scheme, the laser reduced graphene / MXene patterned composite electrode is prepared by the laser direct writing technology after low-cost graphene oxide and an MXene solution are mixed, and the laser reduced graphene / MXene patterned composite electrode is used as a sensing and energy storage material, so that a multifunctional passive self-powered electronic skin system is designed.

Description

technical field [0001] The invention relates to a preparation method of a self-powered electronic skin system based on a laser-reduced graphene / MXene composite material, which can be used in the cross-technical fields of energy storage and sensors. Background technique [0002] In recent years, there has been a growing demand for wearable electronics for human health monitoring and biomedicine. Traditional wearable devices are usually integrated into rigid substrates and limited to work in a limited area, and an external power supply will increase the complexity of the device and reduce the integrity of the device. [0003] At present, among various sensors used to detect human motion and monitor health conditions, piezoresistive sensors are typical sensors that convert external pressure into resistance signals. Due to their low manufacturing cost and simple structure, they are widely used in wearable devices. Has been widely used. Among various energy storage devices, sup...
