Bone Density Scale Hardware
Budget: $25 – $50 USD
I am building DigitScale IA, a dedicated body-composition scale that goes beyond mere weight and zeroes in on bone density. The goal is a standalone hardware device—complete with its own enclosure, sensing module, firmware and simple companion interface—that can provide reliable, non-invasive bone-density readings each time a user steps on it.
Your expertise in sensor selection, PCB design, firmware development and calibration will shape the entire product. Feel free to propose capacitive, impedance-based, ultrasound or hybrid approaches; accuracy and repeatability are the metrics that matter most. Bluetooth LE connectivity is preferred so users can pull their data into a mobile app later, but a basic on-device display will suffice for the first iteration.
Deliverables
• Schematics, PCB layout and full bill of materials
• Embedded firmware with documented code and calibration routine
• Mechanical design files suitable for 3-D printing or CNC prototyping
• Validation report comparing bone-density results against a commercial reference device
If you have worked on smart scales, medical sensing, or low-power Bluetooth devices, let me know; those skills will accelerate the project.
