Embedded World 2026: Five embedded systems trends from the show floor

Something has clearly shifted in the embedded industry.

After a week at Embedded World in Nürnberg, one theme kept surfacing again and again in conversations with customers, partners, and engineers: embedded systems are rapidly moving into environments where reliability, resilience, and data integrity are no longer technical considerations. They are strategic requirements.

Devices are becoming more autonomous, more connected, and increasingly responsible for critical workloads in industrial systems, vehicles, infrastructure, and intelligent machines. As a result, the software infrastructure underneath these systems is becoming just as important as the hardware itself.

Our Tuxera team spent the week meeting with companies across the ecosystem, and several themes emerged repeatedly.

Here are five takeaways that stood out.

1. Embedded systems are moving deeper into mission-critical environments

Across industries, embedded systems are increasingly powering environments where failure simply is not an option. Whether it is robotics on a factory floor, autonomous vehicles, or large-scale industrial infrastructure, reliability and safety certification are becoming central design requirements. Many vendors highlighted certified stacks and deterministic system behavior as key differentiators.

This shift reinforces the growing importance of infrastructure software that can guarantee data integrity, predictable performance, and fast recovery when something goes wrong.

2. Physical AI is emerging

Physical AI refers to AI systems that interact directly with the physical world — machines, sensors, and industrial environments — rather than operating purely in software or the cloud. AI was everywhere at Embedded World, but the more interesting shift is where AI is moving: closer to the physical world. We are seeing early examples of AI systems interacting directly with machines and industrial environments.

Industrial automation systems analyzing vibration and acoustic signals to predict equipment failures were one example frequently discussed during the event. These systems depend heavily on reliable data flows and resilient infrastructure. If the data layer fails, the intelligence layer fails with it.

3. Infrastructure reliability is becoming strategic

As embedded systems become more connected and data-driven, the reliability of the underlying infrastructure is moving from an implementation detail to a strategic architectural decision. Embedded storage reliability, data integrity, and system resilience are increasingly shaping system design.

One example discussed during the event illustrates the point well: in some smart meter deployments, the operational cost of a meter failure can be three times higher than the cost of the device itself — a figure that underscores just how expensive downtime has become in connected infrastructure. In these environments, preventing failure becomes far more valuable than reducing hardware costs.

4. OTA updates are becoming a cloud-scale challenge

A phrase we heard repeatedly during the week was that “OTA is now an IT problem.” Over-the-air (OTA) updates for embedded devices increasingly resemble cloud-scale software deployment. The difference is that embedded devices often operate in environments where engineers cannot easily recover a system if something goes wrong. This is driving demand for smarter update mechanisms and resilient storage architectures that allow devices to recover safely from failed updates or interrupted deployments.

5. Security requirements are increasing across the stack

Security also surfaced as a growing concern across many conversations. Companies are facing increasing requirements around encryption, secure storage architectures, and protecting sensitive device data. One specific request that came up was support for file system-level encryption for individual files. Regulations such as the EU Cyber Resilience Act (CRA) are also pushing companies to reassess their designs through a security-by-design lens across the entire embedded software stack.

As embedded devices become part of critical infrastructure and connected ecosystems, protecting data throughout the entire stack is becoming a design requirement rather than an optional feature.

For us at Tuxera, many of these trends reinforce the direction we have been investing in for years. As embedded systems become more autonomous, data-driven, and mission-critical, the infrastructure layer becomes increasingly important. Reliable storage, data integrity, and resilient system behavior are foundational capabilities for the next generation of embedded platforms.

Embedded World was also a great moment for our team. We had the opportunity to meet many customers and partners across the ecosystem and showcase the technologies we have been developing. It was particularly exciting to see NitroFS — Tuxera’s certified embedded file system designed for reliability and fast recovery in mission-critical storage environments — recognized with the Embedded World Best in Show award, highlighting the growing importance of reliable storage infrastructure in modern embedded systems.

If one theme captured the event this year, it is this: as embedded systems move closer to the physical world and take on more critical workloads, the reliability of the infrastructure underneath them will matter more than ever.
