Stretchable electronic skin based on paper-cut structure, and preparation method and application thereof

Abstract

The invention discloses stretchable electronic skin based on a paper-cut structure. According to the electronic skin of the paper-cut structure, cutting gaps are formed in the electronic skin. The electronic skin with the paper-cut structure is of a single-shaft paper-cut structure, a double-shaft paper-cut structure or a square spiral paper-cut structure. The electronic skin of the single-axis paper-cut structure is that cutting gaps are longitudinally and periodically arranged on the electronic skin; the electronic skin of the double-shaft paper-cut structure is that cutting gaps are periodically arranged on the electronic skin in a latticed mode; and the electronic structure of the square spiral paper-cut structure is that cutting gaps are periodically arranged on the electronic skin in an L shape. According to the stretchable electronic skin based on the paper-cut structure provided by the invention, the electronic skin of the paper-cut structure has good stretchability; and therefore the electronic skin can be better attached to the skin. The invention also provides a simple and convenient preparation method of the electronic skin, and also provides application and a method for monitoring human physiological signals by the electronic skin.

Description

technical field [0001] The invention belongs to the technical field of electronic skin, and in particular relates to a stretchable electronic skin based on a paper-cut structure and a preparation method and application thereof. Background technique [0002] Liquid metal-based bilayer electronic skin with asymmetric structure and electrical properties on both sides plays an important role in microscale sensors / actuators, energy storage / generation devices, and thermal management. The bilayer film electronic skin provides convenience to solve the challenges involving electronic circuits and energy management, effectively prevents internal short circuits of circuits, and realizes complex functions in a limited space. However, the traditional liquid metal bilayer electronic skin is not stretchable and does not match the elastic modulus of the skin. The traditional double-film electronic skin is not combined with the skin sensing function, and cannot sense human physiological sig...

AI Technical Summary

Problems solved by technology

However, the traditional liquid metal bilayer electronic skin is not stretchable and does not match the elastic modulus of the skin.

The traditional double-layer film electronic skin is not combined with the skin sensing function, and cannot perceive human physiological signals well

In addition, the traditional double-layer electronic skin cannot be recycled and reused, so it is very important to prepare a double-layer electronic skin that is stretchable, recyclable and can sense human physiological signals.
