[The working principle and prototype construction of the Chinese vestibular prosthesis]

Area of Science:

• Biomedical Engineering
• Neuroprosthetics
• Vestibular System Research

Background:

• The development of advanced neuroprosthetics is crucial for restoring sensory function.
• Vestibular prostheses aim to address balance and spatial orientation disorders.
• Independent intellectual property rights are essential for clinical translation.

Purpose of the Study:

• To design the working principle and construct a prototype of the Chinese multichannel vestibular prosthesis (CMVP).
• To verify the performance of the CMVP prototype.
• To establish a foundation for the clinical promotion and application of CMVP.

Main Methods:

• Information encoding principle of the vestibular nervous system was used to construct the CMVP working principle.
• Circuit design was performed based on the established working principle.
• Prototype construction involved selecting appropriate electronic components and software systems, followed by performance testing.

Main Results:

• A detailed block diagram and explanation of the CMVP working principle were successfully created.
• The CMVP prototype was constructed, demonstrating biphasic pulse current output from all stimulus electrodes.
• The frequency of the pulse current output was effectively modulated by spatial rotation data from a motion sensor.

Conclusions:

• The working principle and circuit design of the CMVP are deemed reasonable and scientifically sound.
• Successful construction of the CMVP prototype in China has been achieved.
• The CMVP exhibits stable and reliable performance in spatial rotation sensing and modulated pulse current output.
