Electronics, software
and acoustics
for medical devices and instrumentation.

ST-LINE designs electronics, firmware and software for medical, industrial and scientific devices, alongside acoustics services delivered by technicians on the Italian national register. A single technical partner from concept to the documentation the regulatory route requires.

// WHERE YOU START

Building a medical device or precision instrumentation?

From electronics to firmware to software, through to CE marking and FDA clearance — with people who have already been through certification.

When we’re not building for clients,
we open the lab.

Open-source projects we develop and optimise — from our acoustic calculation tools to contributions on simulation solvers. One of them — our camera-sensor bring-up tool — is cited by Arducam itself in its own official documentation.
