Community project · Non-profit

Medical devices that think on the spot, for clinics without specialists or internet.

Edge AI for Health is a student-led project by Hoang Anh Nguyen at Hanoi University of Science and Technology. I design low-cost devices that run AI on the chip itself, so they work offline and patient data never leaves the device.

Why this project

A good examination shouldn’t depend on where you live.

  1. Few specialists at the front line

    A commune health station is often a patient’s first and only stop, yet heart and lung sounds take years of practice to judge well.

  2. Cloud AI doesn’t reach the village

    Many smart tools stop working when the connection drops — exactly in the places that need them most.

  3. Imported devices cost too much

    Each device uses common, affordable parts so a health station could own one, repair it, and build another.

Design principles

Four rules every device follows.

  • Works offline

    The AI runs on the device’s own chip. No signal, no problem.

  • Data stays on the device

    Recordings are processed and kept locally, never uploaded by default.

  • Affordable and repairable

    Off-the-shelf parts that a local technician can source and replace.

  • Open to the community

    Designs and code are shared as each device reaches a safe, documented stage.

The devices

One approach, four everyday problems.

In development

Cough Listener

A small box for clinic waiting rooms that picks out coughs from background noise and suggests who may need TB or pneumonia screening.

In development

Single-lead ECG Patch

A thin chest patch worn for several days that watches for irregular heart rhythms such as atrial fibrillation and saves only the moments that matter.

In development

School Hearing Screener

A headphone kit that lets a school nurse run a quick hearing check, with a built-in microphone that pauses the test when the room is too loud.

Illustrations are design drawings, not product photos.

How it works

Every device follows the same four steps — all of them on the device.

  1. Sense

    Sound, heart rhythm or a hearing response, captured by low-cost sensors.

  2. Clean

    Separate overlapping sources and remove the noise of a real clinic.

  3. Decide on the chip

    A small model, sized for a microcontroller, highlights what needs attention.

  4. Show it here

    A clear result on the device. The clinician makes the call.

Research foundation

Built on speech-separation research.

Telling apart several sounds that overlap — three voices at once, a heartbeat under a breath, a cough in a noisy room — is the same problem. My separation research is the core of the acoustic devices.

Who is behind it

Hi, I’m Hoang Anh Nguyen.

I’m a third-year Electronics & Telecommunications student at Hanoi University of Science and Technology. I started with Linux and networking, moved into AI on small hardware, and found the problem I want to spend my time on: bringing careful listening and early screening to places that don’t have specialists.

Get involved

This project gets better with more people in it.

  • Doctors and nurses

    Tell me what your clinic actually needs, review a design, or help test a prototype safely.

  • Students and engineers

    Firmware, PCB layout, signal processing, small models — there is a piece for every skill.

  • Organisations

    Host a pilot at a health station or school, or sponsor parts for the next batch of devices.
