Darmanjo NPWT Devices — ESP32 Wound-Therapy Hardware
Alongside Darmanjo’s platform, I have been designing its NPWT (negative-pressure wound therapy) devices: ESP32-based hardware with pressure sensors and custom electronic boards.
What I worked on
My work with Darmanjo goes beyond its software platform. For some time I have also been designing the clinic’s NPWT devices — the portable negative-pressure wound therapy units patients carry with them during treatment.
The devices are built around the ESP32, pressure sensors, and custom-built electronic boards. My part is the engineering: sensing and controlling pressure reliably, designing the boards around the therapy’s real constraints, and writing the firmware with ESP-IDF.
Medical-adjacent hardware leaves no room for “mostly works”. The design has to stay safe and predictable when a sensor reads unexpectedly or power behaves badly, which is exactly where small, well-understood firmware and careful board design earn their keep.
What it brings together
- ESP32-based NPWT device design
- Pressure sensing & control
- Custom electronic board design
- ESP-IDF firmware written in C
