Advanced Needle Positioning System
By replacing traditional pressure sensors, Smart Inject Mark 2 integrates advanced technologies such as non-contact flow sensors, ultrasonic sensors, accelerometers, and image processing to detect needle positioning externally. This system eliminates contamination risks during drug loading and significantly improves drug administration accuracy, achieving a success rate of over 90%.

Fusion of AI and Robotics
Smart Inject Mark 2 combines AI-driven vein detection with 6-axis robotic arm control, maximizing precision in drug administration. The system uses the Vision Transformer-based SegFormer model to enhance the identification of veins and needle placement, achieving a target accuracy (mIoU) of over 0.9 and real-time processing at 30 FPS, reducing experimental failure rates and improving data reliability.
