Summary
This study introduces a tiny, stretchable neural electrode and wireless power device for precise back pain relief, minimizing side effects associated with conventional therapies.
Area of Science:
- Biomedical Engineering
- Neuroscience
- Medical Devices
Background:
- Spine disorders cause widespread back pain, impacting quality of life and economic productivity.
- Conventional radiofrequency therapies for pain relief have significant side effects due to large stimulation areas.
Purpose of the Study:
- To design a miniaturized, stretchable neural electrode for precise dorsal root ganglion stimulation.
- To develop a subcutaneously implantable wireless power transmission (WPT) device for the neural electrode.
- To mitigate side effects associated with current pain relief methods.
Main Methods:
- Architectural design and simulation of a transdermal wireless power transfer device.
- Development of a wrap-able pulsed radiofrequency (PRF) stimulatory electrode.
- Design of insulation packaging for a titanium protection box.
Main Results:
- Successful design and simulation of the wireless power transmission system.
- Creation of a functional wrap-able PRF electrode prototype.
- Development of a protective insulation packaging for the implantable device.
Conclusions:
- The developed system offers a precise and potentially safer alternative for neural stimulation in back pain management.
- The tiny, stretchable electrode and WPT device show feasibility for clinical application.
- Further studies and prototypes are warranted to validate efficacy and safety in patients.
