Electrospining Machine: Electrospun Nanofbers for Sensor Applications

Background

A sensor is a device or apparatus capable of sensing and measuring a specific physical or chemical quantity. Sensors can convert sensed information into electrical, digital or other recognisable forms for processing, transmission and analysis. Sensors are widely used in industrial, medical, environmental monitoring, automotive, and consumer electronics applications.

What are the requirements for materials

Materials used for sensors need to be sensitive, stable, specific, preparable, reliable, and responsive.

What are the techniques for preparing Electrospun Nanofbers for sensors?

Electrospun Nanofbers for sensors are prepared by a large number of methods, and common methods include electrospinning, template method, and self-assembly techniques. Among them, electrostatic spinning is a commonly used technique for the preparation of Electrospun Nanofbers by stretching polymer solution or molten polymer into fibres under the action of a high electric field to form a nanoscale fibre structure. Electrospun Nanofbers prepared by this method have high specific surface area and fine diameter, and have a wide range of applications in the field of sensors

Electrospun Nanofbers for Sensor Applications

Nanofiber Membrane prepared by electrostatic spinning technology has many advantages such as small scale, large specific surface area, high porosity, easy doping functional modification and controllable structure, which can simultaneously improve the sensor's sensitivity, response time, durability and other performance indexes from the selection of raw materials, structural design and other aspects. Especially in terms of structural design, more use of various biomimetic structure design

This paper systematically describes the structure and preparation process of Electrospun Nanofbers and conductive layers. The influence of the material and structure of Electrospun Nanofbers on wearable strain sensors is outlined, and the following discussion of sensing performance optimisation strategies is outlined. In addition, applications of wearable strain sensors based on Electrospun Nanofbers in biomonitoring, motion detection and human-computer interaction are presented.

2.Electrospun Nanofbers in Environmental Sensors

Environmental sensors are one of the key technologies for environmental monitoring, which ultimately empowers environmental protection.Environmental sensors made of Electrospun Nanofbers have many advantages, such as having a porous structure and a high specific surface area, which effectively improve their performance in environmental sensing. This paper reviews the research progress of Electrospun Nanofbers with different morphological and functional characteristics in environmental sensors in the last decade.
