Technical Deep Dive
- Material Composition: Employs a composite of silver flakes and a thermoplastic polyurethane (TPU) binder to ensure flexibility and conductivity.
- Fabrication Method: Utilizes a stencil-based application technique where the ink is painted directly onto the skin, bypassing high-temperature sintering requirements.
- Signal Processing: The serpentine geometry of the conductive traces minimizes mechanical strain, preventing signal artifacts during patient movement.
- Biocompatibility: The ink formulation is designed to be non-toxic and non-irritating, allowing for extended wear without dermatological issues.
- Connectivity: Designed to interface with external wireless data acquisition modules via thin, flexible interconnects.
