Investigation of non invasive feedback in prosthetic limbs
PhDs and postgraduate research
Funded PhD Project (UK and EU students only)
School of Energy and Electronic Engineering
This project is now closed. The details below are for information purposes only. View our current projects here.
The PhD will be based in the School of Energy and Electronic Engineering and will be supervised by Professor Peter Kyberd.
The bursary is available to UK and EU students only and covers tuition fees and an annual maintenance grant in line with the RCUK rate (£15,009 for 2019/20) for three years. The Faculty of Technology may fund project costs/consumables up to £1,500 p.a.
On this project, you will:
- Develop experimental protocol
- Develop apparatus
- Gain ethical approval for experiments with healthy volunteers
- Recruit volunteers
- Conduct experiments with volunteers
- Analyse data
- Gain ethical approval for experiments with prosthesis users
- Recruit volunteer users
- Conduct experiments with users
- Analyse data
- Write up and present results
The mechanical design of prosthetic hands has greatly improved in the last decade, but the level of control of those hands has not developed as quickly. Compared to the amount and types of feedback experienced by a person with a natural hand, powered prosthetic hands have very limited feedback, usually only visual.
Internal feedback to the nerves of the user is still difficult and will be expensive for the foreseeable future – but non-invasive feedback to the skin is a more practical and immediately achievable aim.
When other forms of feedback, such as force, are applied to prosthetic limbs they tend not to improve the functional performance of the operator. This could be because the feedback is not of the right form or perhaps fed to the user in the wrong way. This project aims to investigate why feedback forms are not usable, and to find ways to improve the performance by adopting the correct approach.
The successful candidate will study the use of feedback to enhance prosthetic grasping. You'll begin by creating tests and using unimpaired volunteers explore the limits of different feedback modalities – from vibration to force, heat to pressure, and the different senses being reproduced (force, touch, motion, proprioception and temperature).
The tests will include sensory substitution, where one external sense is replaced by another fed back (for example, force for vibration). The tests will involve both Virtual Reality as well as physical simulation of grasping and manipulation, and will explore which sense is useful, under which circumstances.
When the tests have sufficiently improved our understanding of the problem – and identified the most effective solutions – the tests will be adapted so they can be applied to users of prosthetic limbs in the lab. As a stretch goal, the systems may be further adapted for use in the field by a selected few prosthesis wearers.
- You'll need a good first degree from an internationally recognised university (minimum 2.1 or equivalent) in Engineering, Bioengineering, Applied Psychology or a related subject, or a Master’s degree in an appropriate subject, and a desire to excel as a researcher together with disciplined work habits.
- Exceptionally, equivalent professional experience and/or qualifications will be considered.
- English language proficiency at a minimum of IELTS band 6.5 with no component score below 6.0.
You must be familiar with programing techniques and prepared to learn to work with electromechanical hardware, when appropriate. You’ll have significant interaction with volunteer subjects (general population and prosthesis users), must be able to apply for ethical permission and recruit volunteers.
In particular, we’d welcome candidates with:
- programming skills
- good interpersonal skills
- an engineering or psychology degree
- mathematical knowledge
- interest in biomedical engineering
- flexible approach
