CorePlate™ 3D Chip

🏗️ Working Principle: 3-Layer Architecture

| Layer |
Key Finding |
| 🔍 Macro Layer |
Central well holds organoid; metal contacts connect to external device |
| 🔬 Meso Layer |
3D electrode pillars penetrate tissue bottom, recording deep inside |
| 🧬 Micro Layer |
Neuronal axons/dendrites wrap around pillar electrodes, gold tip is recording site |
💡 Data Flow: Neuronal action potential → 3D microelectrode coupling → Ion-to-electron conversion → External digitization
