Upgrade EMG Biofeedback Prototype

I have a working surface-EMG biofeedback prototype that is almost ready for a clinical trial. My background is in Occupational Therapy, so I need a technically-minded partner to finish the engineering details.

The prototype already captures clean EMG signals, but three areas still need work before it enters the clinic:

1. Fixing the vibration sensor
• Diagnose the current instability (occasional dropouts and inconsistent amplitude)
• Re-calibrate and, if necessary, replace the sensor so it triggers haptic feedback within 50 ms of threshold detection
• Deliver updated firmware and wiring diagram

2. Building EMG display software for Windows
• Real-time data visualization (raw signal and RMS/average)
• Session recording to CSV or similar format for later analysis
• A user-friendly interface designed for clinicians with minimal technical training
• Installer, full source code, and brief user manual

3. Other minor modifications
• Tidy PCB layout and enclosure fit
• Basic documentation so the device package is ready for ethics approval/IRB review

Preferred tools are open to you (C#/WPF, Python + PyQt, or C++/Qt are all fine) as long as the final executable runs on Windows 10 without admin rights.

Acceptance criteria
• Vibration feedback latency < 50 ms and repeatable across 100 trials
• Software streams at ≥ 1 kHz with no frame drops for at least 30 minutes
• Recorded files open correctly in Excel or MATLAB/R
• Clear, illustrated documentation covering hardware changes, build steps, and clinician workflow

If this sounds like your expertise—especially if you’ve shipped medical or wearable prototypes before—please outline your approach, timeline, and any similar projects you have completed. I’m ready to start as soon as we agree on the plan.
