This EPSRC DLA 3.5-year PhD project at Cardiff University focuses on developing a self-adaptive, energy-harvesting lower limb prosthesis for rehabilitation. The research addresses the limitations of current rehabilitation devices, which often provide passive assistance and can lead to patient dependency, by introducing a lightweight, intelligent prosthesis system designed for long-term, home-based rehabilitation. The system features two main innovations: an energy-harvesting mechanism for self-sustained operation and an adaptive control algorithm that encourages active muscle engagement, supporting targeted muscle activation as prescribed by physiotherapists. The project leverages OpenSim, an open-source biomechanical simulation tool, to model lower limb movements during rehabilitation tasks such as sit-to-stand. These simulations will help identify optimal phases for energy harvesting and inform the timing and magnitude of prosthesis assistance and resistance, forming the basis for a control framework that balances effective rehabilitation with energy efficiency. The adaptive algorithm will use real-time electromyography (EMG) feedback to personalize assistance, ensuring muscle activation remains at optimal levels for each user. Initial validation will be conducted with healthy participants, followed by pilot testing with patients diagnosed with knee arthritis. The project builds on an existing prototype and aims to advance the technology towards a fully intelligent, energy-autonomous rehabilitation device, contributing to the field of precision rehabilitation and supporting independent recovery in home settings. Applicants should have a strong background in Engineering or a related field, with a first-class or good 2.1 degree (or equivalent), and meet English language requirements (IELTS 6.5 or equivalent). Full funding is available for both Home and International students, covering tuition fees and a competitive stipend. The application deadline is January 9, 2026, with interviews for shortlisted candidates. For more information, prospective applicants can contact Dr Shou-Han Zhou at Cardiff University.
