Working with Nordic’s nRF9160 has been one of the most technically rewarding journeys in IoT firmware engineering. On the surface, it is a powerful module that combines LTE-M, NB-IoT, GPS, and an ARM Cortex-M33 in a single ultra-low-power package. For asset tracking, healthcare wearables, remote diagnostics, industrial telemetry, and logistics systems, it appears ideal. But here’s what many teams […]
Debugging battery drain in a wearable’s firmware starts by measuring what the device draws when it should be asleep, then finding which peripheral, interrupt or task is keeping it awake. The faults are small, a few microamps or a timer firing too often, and invisible in lab testing. They only show up as battery life

Artificial intelligence has crossed an important threshold in clinical diagnostics, and healthcare is beginning to feel the impact. For years, AI systems in radiology, pathology, and clinical decision support were positioned as assistants. They highlighted anomalies, suggested possibilities, and improved workflow efficiency. The final decision always remained with clinicians. That boundary is changing. With regulatory approvals validating AI tools

Medical implants have always represented the intersection of engineering precision and human survival. Devices such as pacemakers, insulin pumps, neurostimulators, and shunts already play a life-saving role in modern healthcare. But a new transformation is underway, one driven by artificial intelligence and embedded computing. We are entering an era where implants will no longer operate as static,
Power optimisation turns a MedTech device that works on the bench into one that works on the patient: it decides how long a monitor runs between charges, whether an alert still fires on a low battery and whether the device passes the safety standards it is sold under. That is the importance of power efficiency

In early-stage MedTech development, hardware usually gets the spotlight. Investors ask about sensors, algorithms, clinical validation, and manufacturing readiness. Teams celebrate when prototypes work reliably in controlled environments. However, as products transition from early development to scaling for real-world deployment, a different reality emerges, one that often catches teams off guard. The challenge is not the

You build an on-device arrhythmia detection system by designing backwards from the constraints of a small medical device: a microcontroller with limited RAM and flash, a strict power budget and continuous ECG sampling, with every detection made on the device, none in the cloud. On-device arrhythmia detection in medical devices is a reliability problem first,

The most significant decision in medical device firmware is made before the application code: RTOS or bare metal? RTOS or bare metal? On the surface, this choice is often framed as a technical preference or performance trade-off. Especially for Class II and Class III medical devices, it is neither. It is a risk-alignment decision. Your architecture shapes how firmware
Choosing Between RTOS and Bare Metal in MedTech Firmware Design Read More »
Firmware loops can quietly drain a wearable’s battery by keeping the processor awake when nothing needs it: a polling loop, a busy-wait delay or a timer set “just to be safe” stops the device ever reaching deep sleep. Firmware loops that drain wearable batteries pass every functional test, because the device works; only the runtime
How Do Firmware Loops Quietly Drain a Wearable’s Battery? Read More »
In most industries, firmware is judged by whether it works. In MedTech, firmware is judged by whether it can be proven to work safely and consistently under every foreseeable condition. You cannot patch your way out of non-compliance. And you cannot debug your way past a failed audit. In medical devices, firmware is not just logic running on silicon. It is
