AI Technical Summary
In existing laryngeal pacemaker systems, high skin impedance and motion artifacts occur when the respiratory sensor contacts the skin, resulting in poor signal detection. Furthermore, existing tattoo electrode sensors cannot establish stable and reliable electrical connections with external devices during long-term use.
A disposable flexible skin-transferable printed tattoo electrode sensor is designed with a removable support substrate and a water-soluble sacrificial layer, combined with stretchable connector traces and magnetic interconnect units to achieve stable and reliable connection with external devices, reduce motion artifacts, and provide a compliant interface between layers of different thicknesses and Young's moduli through soft conductive ink and polyimide foil materials.
It achieves stable contact with the skin during long-term use, reduces motion artifacts, can monitor respiratory signals in real time, and establishes a stable electrical connection with external devices. It is suitable for respiratory signal acquisition in laryngeal pacemaker systems, avoiding the irritation and signal quality degradation problems of traditional electrodes.
