Miniaturized Medical Device Development
Budget: $25 – $50 USD
I’m building a wearable, battery-powered device that treats urinary incontinence by driving a micro-stepper screw mechanism. The work is split into two closely related phases and I’m looking for one partner who can carry both through to prototype stage.
Phase 1 covers the electronics and firmware. I already have the functional blocks defined: a Li-Po cell, an inductive charger coil, an MCU (Arduino-class or equivalent), and the stepper driver. Your job is to turn that into a production-ready schematic, compact multilayer PCB, and embedded code that moves the screw precisely, monitors battery/temperature, and exposes a USB-CDC interface for configuration.
Phase 2 brings connectivity and user interaction. I need the same hardware miniaturised even further, Qi or another suitable inductive standard selected, and Bluetooth LE added so the device can talk to an Android phone. On the software side you will deliver:
• A lightweight Windows PC utility that lets clinicians adjust treatment parameters, monitor live telemetry, push firmware updates, and, when authorised, trigger the device manually.
• A companion Android app offering the same capabilities over BLE with a straightforward, medically-oriented UI.
Acceptance criteria will be joint bench tests confirming step accuracy, charge efficiency, and reliable parameter transfer over both USB and Bluetooth. I’m open on toolchains, but please indicate if you favour KiCad, Altium, STM32CubeIDE, PlatformIO, Android Studio, etc., as I’ll need the full project files at hand-off.
If you have end-to-end experience in wearable medical hardware, inductive power, and cross-platform apps, I’d love to hear how you’d approach this.
