Summary
Researchers developed a wearable repetitive transcranial magnetic stimulation (rTMS) device, significantly reducing size and power consumption. This innovation enables rTMS therapy during free behaviors and in home settings.
Area of Science:
- Neuroscience
- Biomedical Engineering
Background:
- Repetitive transcranial magnetic stimulation (rTMS) is a valuable tool for treating neuropsychiatric disorders and brain research.
- Current rTMS devices are limited by large size and high power consumption, restricting their use in free behaviors and home settings.
Purpose of the Study:
- To develop a portable, battery-powered wearable rTMS device.
- To overcome the limitations of conventional rTMS systems for broader applications.
Main Methods:
- Utilized lightweight magnetic core coil designs.
- Implemented high-power-density, high-voltage pulse driving techniques.
- Developed a battery-powered wearable stimulator weighing 3kg.
Main Results:
- Achieved a 90% reduction in power consumption compared to commercial devices.
- Maintained comparable stimulus intensity and repetition frequency.
- Demonstrated enhanced cortical excitability during free walking, linking leg activity to arm cortex excitability.
Conclusions:
- The developed wearable rTMS device is effective and portable.
- This technology facilitates high-frequency rTMS modulation during free behaviors.
- Enables convenient home and community-based rTMS treatments for wider accessibility.
