The future of medical device development lies not in traditional programming, but in prompt engineering. NewPrompt demonstrates how advanced AI models (Codex, Claude, GPT-4) integrated into Visual Studio on Raspberry Pi enable rapid prototyping of embedded medical systems. Our approach: engineers describe what devices should do—AI generates the code. We’ve validated this methodology across three confidential projects (currently in patent process) in diagnostics, rehabilitation, and patient care. The result? Microcontrollers that program themselves, dramatically reducing time-to-prototype from months to days.
