PhD Study : Electro-mechanical spinning (EMS): Innovative Technique to scale-up efficient nanofibers mats for wearable electronics applications

Summary

The proposed project focuses on advancing a critical technology in materials engineering: the scaled-up production of nanofiber mats. Nanofibers are incredibly thin fibres, below micron scale, with applications of high-tech clothing for health monitoring. Currently, the main method for creating these fibres is process called electrospinning, which uses electric fields to form the fibres. While effective, electrospinning can only produce fibers-mats on a relatively small scale, limiting their commercial and industrial potential.

To address this limitation, the project proposes the development of a new technology that combines the traditional electrospinning process with a method known as solution-blown spinning. This hybrid technique, named electro-mechanical spinning (EMS), will incorporate electric fields within air-based fibre production to allow larger-scale manufacturing without compromising fibres’ quality.

The research will explore various aspects of this new system, including the power, distance, feeding rate, and air pumping, necessary to create the fibres, along with optimized location of electrodes. The project will involve rigorous testing with different polymer materials to understand the effects of this new method on the fibres’ properties.

As part of the project, piezoelectric nanofibers, which can convert mechanical stress into electrical energy, will be produced for use in wearable electronics. These materials have exciting applications, such as energy-harvesting clothing that can charge devices or monitor vital signs like heart rates and breathing. The project will compare the quality and performance of fibres produced by this new method with those made by existing techniques.

The benefits of this project extend beyond technology. It aligns with the UK’s industrial strategy to foster innovation, supports business growth, and helps train a skilled workforce. By scaling up the produced versatile fibres, the project promises significant advancements for various industries and consumers globally. The proposed research integrates different engineering disciplines including mechanical, electrical, and composite manufacturing engineering.
