Embodiment Construction

[0032] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0033] The typical structure of the all-nanofiber electronic skin provided by the present invention can be found in figure 1 with figure 2 , the electronic skin includes three layers of nanofiber membranes, upper, middle and lower, which are the upper contact electrification layer 1 , the middle electrode layer 2 and the bottom support layer 3 . The electronic skin utilizes the principle of triboelectric nanogenerator, and its working mode is a single-electrode working mode. When an external object, such as human skin, contacts and separates from the contact electrification layer 1, an alternating current signal will be generated between the intermediate elec...

Abstract

The invention provides a full-nanofiber electronic skin which comprises an upper nanofiber membrane, a middle nanofiber membrane and a lower nanofiber membrane which are a contact electrification layer, a middle electrode layer and a bottom supporting layer respectively. The contact electrification layer and the bottom supporting layer are both nanofiber membranes made of biodegradable materials.And the middle electrode layer is a nanofiber membrane with a sterilization function and is electrically connected with the ground or other conductors. The electronic skin is provided with a pluralityof layers of staggered nanofiber networks and a large number of three-dimensional micro-nano hierarchical pores, so that the electronic skin has air permeability, high output, high pressure sensitivity and antibacterial property.

Description

technical field [0001] The invention relates to the field of sensors, in particular to an all-nanofiber electronic skin and an application device thereof. Background technique [0002] As the largest organ of the human body, human skin not only has the basic functions of protection, secretion and respiration, but also is an important somatosensory system for human perception, interaction and communication with the material world. By mimicking the features and functions of natural skin, considerable interest has been aroused in the development of biomimetic electronic skins in wearable person-centric health monitoring, smart prosthetics, robotics, human-machine interfaces, and artificial intelligence, etc. The field has a wide range of applications. [0003] Based on different physical sensing mechanisms, such as piezoresistive, capacitive, piezoelectric, and triboelectric, e-skin can detect and quantify the diversity of environmental stimuli, including temperature, humidity...
