Why firmware update architecture mission-critical for secure OTA defence systems
Insecure OTA defence systems are a critical and often overlooked vulnerability. Explore the firmware update architecture decisions that determine the security ceiling of any deployed defence IoT system
MAVLink integration in defence UAVs: Architecture, security and deployment considerations
What is MAVLink and why does it matter for defence UAV integration? UAVs (unmanned aerial vehicles, more commonly called drones) have moved from niche military tools to a central component of modern defence operations, used for reconnaissance, logistics, and...
Exploring LoRa defence communications for military-grade applications
Why LoRa Is Emerging as a Credible Protocol for Deployed UK Defence Sensor Systems The UK’s Defence Technology Framework and the broader Defence and Security Equipment International (DSEI) agenda have both placed persistent battlefield awareness at the centre of...
Building Compliant IEC 62304 Embedded Software for Medical Devices
Why IEC 62304 is the cornerstone of UK medical software compliance As we’ve seen across the board in this series centred on medical device compliance, integration and privacy, a persistent myth in product development is that software is somehow a secondary layer added...
Medical Device Cybersecurity Design: Principles, Standards, and Best Practices
Medical Device Cybersecurity Design: Principles, Standards, and Best Practices Designing secure embedded systems for medical devices There is a persistent assumption in connected medical device development: that medical device cybersecurity design and privacy are...
IEC 60601 Wireless Compliance Explained: EMC, Protocol Selection and Regulatory Pathways
The compliance trap: What engineers and product leaders need to know about IEC 60601 wireless compliance Wireless connectivity has become a near-universal expectation in medical device design. From remote patient monitoring, wireless firmware updates, and real-time...
Wireless Charging in Medical Wearables
Engineering wireless power transfer for clinical-grade wearable medical devices Battery charging is simultaneously one of the least glamorous and most consequential problems in medical wearable design. A device that requires the patient to locate a proprietary cable,...
BLE in Wearable Medical Devices
Engineering high-performance IoMT solutions for clinical viability Despite their potential, most wearable medical devices encounter challenges in clinical integration. The sensors exist, so it’s not because they can't sense the right signals. In most cases, it's the...
Condition Monitoring for Rotating Assets
Condition Monitoring for Rotating Assets: Beyond the Vibration Sensor Asset condition monitoring: Converting unplanned emergency repairs into proactive interventions In industrial environments, rotating assets (such as motors, pumps, compressors, or monitors that are...
NB-IoT vs LTE-M for utilities: Selecting the right connectivity architecture
Low-Power Wide-Area Network (LPWAN) technologies & energy digitalisation As the UK utilities sector continues to move towards a decentralised system focused on grid modernisation, digital tools and high-quality data are fundamental to designing a system capable of...
Rugged electronics for substations
Electronics design constraints for substations Substations are essential to national power networks, stepping voltage up or down throughout the supply chain. They transmit high-voltage electricity over long distances and distribute it at lower voltages for end users....
LoRaWAN for remote energy monitoring
Wireless Networking Protocols for Energy Monitoring: Benefits & Constraints Increased geopolitical tensions, supply chain disruptions, and heightened market uncertainty have placed global energy markets in unprecedented instability. Governments are compelled to...
Explosion protection concepts for energy equipment
Explosion protection in hazardous environments The UK energy sector is rapidly pivoting to hydrogen to meet 2050 net-zero targets, aiming for 5GW of low-carbon production capacity by 2030. Hydrogen is the cornerstone of decarbonising emission-heavy industries,...
Designing ATEX-certified wireless sensors
IoT sensor design for safe, scalable connectivity in hazardous environments In the push for industrial digitalisation (i.e., going beyond ‘optimising’ processes and tasks to enable faster, more effective decisions based on real-time data), wireless sensors have become...
ATEX vs IECEx for energy IoT devices
Ensuring safety in product design for explosive environments The ‘move fast, break things’ tech philosophy popularised by Mark Zuckerberg refers to prioritising rapid deployment, iteration, and risk-taking over perfection and stability. But when those ‘things’ are...
