Project description:
"I have a concept for a handheld medical device that administers treatment through targeted neurostimulation, and I now need to turn it into a functional prototype ready for bench testing and early clinical evaluation. The work involves end-to-end hardware and firmware development—schematic design, PCB layout, component selection, and a basic user interface. A compact, patient-safe enclosure and preliminary safety documentation (ISO 13485 / IEC 60601 awareness) are also part of the scope so I can proceed to regulatory consultation later.

My current assets: core treatment parameters, wave-form specifications, and rough sketches of the form factor. What I still require is the engineering expertise to translate these assets into a fully working unit that can reliably deliver the programmed stimulation profiles on demand, log session data, and charge via USB-C.

Deliverables that will mark project completion:
• CAD and Gerber files for the electronics and enclosure
• Compiled firmware plus commented source code
• A working prototype shipped to me, validated against the stimulation specs
• Brief verification report summarising electrical safety, output accuracy, and run-time logging

Experience with neurostim devices, micro-current or TENS designs, STM32/ESP32 or similar MCU platforms, and rapid prototyping tools (Altium, KiCad, SolidWorks, 3-D printing) will help keep the timeline tight. If any portion of the build—such as enclosure printing or board assembly—needs to be subcontracted, please state that up front so we can align on lead times." (client-provided description)
