What I built
A wearable acoustic sensing platform for gastrointestinal sounds, built end to end: the analog front end, the impedance-matching design that couples the sensor to the body, the PCB, the firmware, and the enclosure. The board streams to a desktop app for visualisation, annotation and analysis, and gives the wearer real-time audio and haptic feedback.
The design was first done in Altium and later redesigned in KiCad so the whole platform is reproducible from an open bill of materials.
