Industrial sensors for harsh environments

Today's remote sensing and actuating systems are widespread. From niche use cases, they have transitioned to pervasive deployment, bringing enhanced control, optimization, and safety. CSEM sensor technologies answer extreme expectations that commercially available products or traditional approaches don’t. Many challenges tied to the operating environment (e.g. temperature, obstacles to radio waves, biological tissues) and to the device (e.g. size, autonomy, cost, sensing strategy). This is precisely where an interdisciplinary team helps win the battle to bring a technically and commercially viable solution.

The pillars of CSEM IIoT solutions are:

• Robustness and compactness
• Resilience in data communication protocols
• Security against cyber-attacks
• Ultra-low power
• AI-driven data processing

Wireless IoT devices need energy to operate. When not connected to the power network, they most often rely on batteries (primary cells) or on accumulators (secondary cells or supercapacitors) when they can harvest energy from the surrounding environment.

Batteries and other energy tanks constrain the power consumption profile of a system. Depending on their structure and chemistry, this results in maximum current peaks and duration, voltage drops, temperature range and dependence, self-discharge rate, and many other effects. To provide the most adequate solution for a specific application, we further characterize commercially available batteries with specific power consumption profiles. We also prototype with industrial prototypes from innovative battery companies and startups and which are close to industrial release (e.g. solid-state, sustainable). We have created and further expand a knowledge base critical to our customers.
