Design, manufacture and application of MXENe-based flexible sensor in Electronics/Materials Science
Background: MXene is a new type of two-dimensional layered nanomaterials, which has excellent electrical conductivity, mechanical strength, optical properties, etc., and is suitable for making flexible sensors. Flexible sensor is a device that can sense external stimuli and convert them into electrical signals, which can be applied to smart skin, wearable electronics, human-computer interaction and other fields.
Project introduction: This project aims to use MXene to prepare flexible force sensor, and explore its resistance change rule under different strains, as well as its application in human motion detection.
Project content:
Ti3C2 MXene nanosheets were prepared from MAX phase precursor by chemical etching and intercalation, and Ti3C2 MXene thin films were prepared by vacuum filtration.
By measuring the resistance-strain curve of Ti3C2 MXene thin film, the force sensitivity and stability of Ti3C2 Mxene thin film are studied.
By connecting Ti3C2 MXene films with conductive tape or wires, flexible force sensors are constructed and tested for their response to different types of human movements such as bending, stretching, punching, etc.
By analyzing the output signals of flexible force-sensitive sensors, different human motion patterns are identified and their potential applications in human-computer interaction are evaluated.
Topic innovation:
The use of MXene as a flexible force sensor material overcomes the defects and inhomogeneity of traditional materials (such as carbon nanotubes, graphene, etc.) in the preparation process, and improves the performance and reliability of the sensor.
Ti3C2 MXene film was prepared by a simple vacuum filtration method, avoiding the complicated transfer or deposition process, reducing the cost and difficulty.
By connecting Ti3C2 MXene film with conductive tape or conductive wire, the flexible force sensor can be made quickly and easily, and its operability in practical applications is improved.
By testing the response of the flexible force sensor to different types of human movement, it shows its wide application prospect in smart skin, wearable electronics, human-computer interaction and other fields.
