Area of Science:

  • Biomedical Engineering
  • Medical Education Technology
  • 3D Printing Innovations

Background:

  • Static 3D printed anatomical models offer limited interactivity for educational purposes.
  • Enhancing 3D models with feedback mechanisms can improve trainee comprehension and patient communication.

Purpose of the Study:

  • To develop and prototype an interactive "smart" 3D printed anatomical model.
  • To integrate voice-activated light-emitting diodes (LEDs) for real-time anatomical structure identification.

Main Methods:

  • Segmentation and 3D printing of ventricular and cisternal systems with a 2.5-mm wall thickness.
  • Integration of wired LEDs at anatomical landmarks connected to an Arduino Uno microcontroller and Bluetooth transceiver.
  • Development of C++ code for voice command recognition via an Android device and Google's voice recognition engine.

Main Results:

  • Successful creation of a functional prototype demonstrating voice-activated illumination of specific anatomical structures.
  • The system effectively translates verbal commands into LED activation, providing immediate visual feedback.
  • Established a communication pathway between a cellular device, microcontroller, and LEDs within the 3D model.

Conclusions:

  • The developed "smart" 3D model serves as a prototype for future interactive anatomical education tools.
  • This technology has potential applications in medical training, patient counseling, and anatomical visualization.
  • Future advancements in 3D printing could enable integrated conductive materials for more seamless feedback device incorporation.
