Connected Device Engineering

From sensor concept to validated, production-ready connected devices

We design and develop connected devices that combine advanced sensors, robust electronics, firmware,
wireless communication and cloud platforms. Our team turns complex ideas into reliable products that
are ready for real environments – from hospitals and factories to cities and logistics networks.

Your full-stack partner for connected devices

Connected devices are no longer just “nice to have”. They must be precise, secure, efficient and easy to integrate into real operations. At Sterna, we bring together sensor expertise, embedded engineering, product design and cloud platforms so you can work with a single partner from first idea to industrialization – with fewer risks and faster cycles.

Sensor & electronics design

We design high-reliability electronics around advanced sensing technologies:

Colorimetry and spectrometry (visible / IR / UV)
Time-of-Flight and distance sensing
Environmental, structural and physiological sensing
Low-power, rugged embedded architectures
High-resolution signal acquisition and conditioning

Firmware & wireless connectivity

We develop firmware and communication stacks that are robust, secure and energy-efficient:

Embedded firmware for ARM / MCU platforms
Power management and low-power modes
BLE, WiFi, NB-IoT, LTE-M, LTE, LoRa and wired Ethernet
Secure communication and OTA update strategies
Integration with existing systems and gateways

Product & UX integration

We connect technology with real users and real workflows:

Mechanical integration and housing design
HMI / UX for devices and dashboards
Usability engineering and ergonomic considerations
Design for harsh or regulated environments
Co-design with clinical, industrial or field teams

Cloud & data platforms

We build or integrate the digital layer that gives meaning to your data:

Scalable backends and APIs (ST Platform or custom)
Dashboards for monitoring, alerts and analytics
Data pipelines, storage and event processing
Edge and on-premise options when required
Secure access, multi-tenant scenarios and integrations

When to work with us

We are the right partner when you need more than a PCB layout or a quick prototype.
We help teams that must bring demanding, high-impact devices to life, often in regulated
or mission-critical environments.

You have a strong product idea but need an engineering team to make it real
You need to integrate advanced sensors with custom electronics and firmware
You want a single partner covering device, connectivity and cloud
Your device will operate in hospitals, factories, cities or critical environments
You need an engineering process aligned with CE and ISO 13485 requirements

Frequent Asked Questions

“Can you work from our existing prototype?”

Yes. We often start from early prototypes or PoC boards. We review the architecture, identify risks, and plan the steps needed to reach a robust, certifiable device.

“Do you only work on medical devices?”

No. While we have strong expertise in medical devices and ISO 13485 alignment, we also develop connected products for industrial, logistics, energy, agritech and smart city applications.

“Can you also support manufacturing?”

Yes. We support DFM, tooling, supplier selection, testing plans and ramp-up, and we collaborate with manufacturing partners when needed.

“What if we already have a cloud team?”

We can integrate with your existing platform or data team, providing well-documented APIs, connectivity strategies and edge logic that fit your architecture.
