Measuring health state by light through skin
Your watch measures exactly one thing: how much light comes back out of your wrist. Everything else — heart rate, sleep, stress, recovery — is inference built on top. Drawing on 165 studies of soldier physiology, we look at what optical sensors genuinely reveal about stress and health, what they cannot, and why their errors all lean toward telling you that you are fine.
What soldiers told us: field-testing sweTAK alongside Signal and ATAK
This spring, Nerio Defense joined a field test comparing Signal, ATAK and sweTAK under realistic conditions. Here’s what 36 soldiers told us about each tool — why familiarity still wins, where sweTAK proved its purpose, what we need to fix, and the smartwatch ideas that emerged from the field.
The Importance of Long-Term Physiological Monitoring for Soldier Readiness and Resilience
Modern military operations demand continuous insight into a soldier’s physical and mental readiness. Nerio Defense — supported by Samsung through advanced biosensors like the Galaxy Ring and Galaxy Watch Ultra 8 — is developing tools that monitor vital parameters such as HRV, blood oxygen saturation, blood pressure indicators, energy and stress levels. Long-term tracking reveals early signs of fatigue, reduced recovery or elevated stress that traditional checks miss. With intelligent analytics, commanders gain a clearer, proactive understanding of readiness, improving safety, resilience and mission performance.
Why the Soldier Needs Automation – Thoughts on Innovation from FMV’s “Omvärld”
The modern soldier is expected to operate in increasingly complex environments – yet most lack even the most basic digital tools. In FMV’s publication Omvärld, Nerio Defense highlights a critical need. At Nerio, we believe automation and intuitive communication tools must become standard for every soldier.
Exploring Radio Mesh Networking Technologies: A Deep Dive into LoRa and Its Alternatives
Radio mesh networking technologies, like LoRa, have transformed industries by enabling long-range, low-power communication for IoT applications. LoRa excels in coverage, scalability, and cost-efficiency, but its limitations include low data rates and latency. Alternatives such as Sigfox, NB-IoT, LTE-M, Zigbee, Wi-Fi HaLow, and BLE Mesh offer tailored solutions for specific needs, ranging from real-time data transmission to high-bandwidth and localized networks. Choosing the right technology depends on factors like range, power consumption, data requirements, and cost. This guide helps you evaluate LoRa and its alternatives to ensure a robust, future-ready deployment for your application.
Lack of Essential Tools
In today’s fast-paced digital world, soldiers struggle with outdated tools that compromise their safety and effectiveness. Limited battery life and cumbersome interfaces create unique challenges on the battlefield. Imagine equipping our forces with advanced technology that provides real-time data and intuitive controls. This modernization isn’t just about civilian advancements; it’s about empowering soldiers to navigate complex combat environments confidently. Embracing digitalization can transform military operations and enhance those who serve.
