About the Project
The School of Engineering of the University of Glasgow is seeking a highly motivated graduate to undertake an exciting 3.5-year PhD project entitled “Functional Nanofiber-based Devices”
The rapidly growing field of wearable systems has opened interesting route for monitoring health remotely through various types of devices that are attached to clothing. The seamless integration of these devices into clothing or e-textile is seen as a way forward to improve the effectiveness of this approach. This project aims to realize smart clothes/patches with functional nanofibers leading to seamlessly integrated electronic devices such as sensors and energy generation. All-nanofiber based generators and sensors integrated with clothing in different sizes and shapes will provide conformal contact with our bodies so that even weaker signals can be detected. These devices will also offer benefits such as lightweight and good air permeability. Specifically, the electrospun conductive nanofibers will be fabricated by optimizing the properties of conductive polymers or composite of polymers with conductive particles (e.g. PEDPT:PSS, PANI or graphene based composites). The all-fibre
devices (e.g. nanogenerator, dynamic pressure sensor) will be fabricated by electrospinning of piezo/triboelectric fibres (e.g. PVDF, PLLA polymers) and conductive nanofibers. The polymer solution properties (e.g. viscosity, composite ratio and conductivity) and electrospinning parameters (e.g.Voltage, flow rate and collector distance) on the morphology and performance of electrospun fibers will be optimized to achieve devices with useful performance. The output voltage and current density of the device under external force will be investigated. The potential use of the fabricated device into a smart cloth to harvest the energy from human motion, monitor some vital health paremeters, and wound healing etc. will be explored.
Eligibility: Min 2.1 undergraduate degree in engineering, physics, materials, chemistry etc. or a cognate discipline.
