AI Technical Summary
Existing concha electrodes suffer from poor contact, suspension, or excessive pressure due to individual differences, resulting in unstable signal acquisition. Furthermore, the passive contact method is prone to displacement during head movement, making it impossible to maintain reliable contact for extended periods.
It adopts a segmented flexible electrode assembly and an active fitting bracket, and uses the shape memory alloy deformation structure to generate deformation within the human body temperature range to achieve adaptive fitting. Combined with magnetic connection and multi-layer composite structure, it ensures that the electrode matches the concha cavity surface.
It significantly improves the fit between the electrodes and the concha, ensures the stability and reliability of signal acquisition and electrical stimulation, reduces system power consumption, and improves wearing comfort and user compliance.
