Development of Conductive Electrospun Materials for Advanced Sensor Applications in Dentistry

Project details: 

This PhD project proposes an innovative exploration into the development of conductive electrospun materials, primarily designed to advance sensor technologies in the field of dentistry. Electrospinning, a versatile technique for creating ultrafine fibres, offers a unique platform for engineering advanced materials with precise control over fibre composition and architecture. The core objective of this project is to combine electrospinning with various conductive enhancement techniques to fabricate novel electrode materials. Importantly, these fibres will be engineered to be inherently soft and highly flexible, making them ideally suited for conformable electronics that can seamlessly adapt to the contours of the skin or internal organs, thereby maximising contact for signal collection while minimising the risk of irritation or mechanical mismatch.

These materials are envisioned to develop new technologies for biometric monitoring, with potential applications in electromyography (EMG), electroencephalography (EEG), electrooculography (EOG), and innovative intraoral sensors for speech and mastication analysis.  These devices are promising for the continuous monitoring of various physiological parameters, potentially aiding in the diagnostic processes related to speech pathologies, temporomandibular disorders, and other dental or maxillofacial conditions.

The project will initially concentrate on the development of materials, allowing for a comprehensive examination of their properties and functional implications. In collaboration with the supervisory team, the successful candidate will have the autonomy to select the specific application they wish to explore. The methodology employs a multifaceted strategy integrating multilayer spinning, selective surface treatments, and spin coating to incorporate conductive elements effectively. Each technique will be optimised to enhance the electrospun fibres’ electrical conductivity and mechanical properties. 

An important phase of the research will be the characterisation of these materials, including assessments of their electrical properties, durability, and biocompatibility—essential factors for sensors used in or on the human body. The project aims to produce electrodes that not only meet but exceed current performance standards in terms of responsiveness, wearability, and signal clarity.

The student undertaking this PhD will gain expertise in advanced material science, electronics, electrospinning techniques, biosignal acquisition and the application of these materials in health-related sensor technology. They will work closely with experts in the field, particularly Dr Paterson, an expert in bioelectronics, and Dr Ortega, an expert in electrospinning. This project not only aims to contribute significant advances to the field of dental research but also seeks to establish a foundation for the wider application of these materials in medical diagnostics and wearable health monitoring systems.
