Real-time 2D pressure mapping from acoustic signals.

Acoustic wearable sensing platform

Viewable soon, once the patent is filed.

Developing an acoustic tactile sensing platform for real-time, 2D pressure mapping in wearable and healthcare applications. My work focuses on characterizing mechanical and acoustic noise and developing robust signal-processing methods to detect pressure-induced events.

Signal quality

Sensing through the noise.

Every step below relies on spectral analysis and real-time FFT.

  1. Pressure from sound

    Determined that relative pressure can be inferred across the grid from its acoustic frequency response, using force-sensing resistors (FSRs) as the comparison reference.

  2. Mechanical noise

    Diagnosed the dominant mechanical noise sources, such as crosstalk, through iterative experiments, then mitigated them mechanically to improve signal quality.

  3. Spike detection

    A real-time algorithm that picks out pressure-induced acoustic spikes under constant noise and a shifting signal baseline, without needing to suppress the noise entirely.

  4. Patent

    Filing is almost underway.
