See battery safety risks before they become failures
Access real measurements from inside the cell to detect anomalies earlier, improve battery safety, prevent unexpected failures, and unlock higher energy yield and longer battery life.
Unlock higher energy yield, safer operation and longer battery life
Cell-level pressure, temperature and leakage data that make your battery more predictable, efficient and reliable
Battery systems rely on precise cell-level data.
FLEXOO’s on-cell, customizable sensors deliver real measurements - pressure, temperature and leakage — providing operators with the information they need to improve efficiency, lifetime and safety.
Cell-level pressure and temperature sensing
Traditional battery monitoring relies heavily on voltage - but in many chemistries, large parts of the operating range are difficult to distinguish based on voltage alone.
Pressure reveals what voltage cannot:
- During charge and discharge cycles, pressure follows a clear, repeatable pattern
- This pattern remains stable over hundreds of cycles
- Even small deviations signal aging and enable real-time SoH assessment
- Early pressure rise indicates internal gas buildup — a pre-indicator of critical failure events
By measuring physical changes directly, internal cell processes become visible - not just inferred.
Leakage detection for cooling loops and electrolyte pathways
Liquid cooling loops and electrolyte-carrying components are critical in high-power battery systems.
Small leaks - whether from cooling lines, seals, interfaces or electrolyte-relevant components - can quickly escalate into performance loss, safety risks or unplanned downtime.
Early leak detection
- Spatially resolved sensor pixels for precise localization
- Immediate resistance change upon contact with coolant or electrolyte
- Wireless data transmission (Bluetooth Low Energy)
- Easy integration into new or existing system layouts
- Reliable monitoring in circular, curved or constrained areas
Leakage is detected where it originates - before system-level effects occur.
A fully customizable sensor platform
All FLEXOO printed sensors are:
- Free-form, layout-customizable and ultra-thin.
- Compatible with prismatic, pouch and cylindrical cells.
- Configurable in density, size and sensing parameters.
- Available with direct BMS connection or wireless readout.
From first prototypes to millions of units, every sensor is built on the same FLEXOO technology stack - ensuring performance, consistency and scalability.
This unified platform means your validation effort is required only once, regardless of production volume or sensor configuration.
Why cell-level sensing matters
From sensing to full battery monitoring systems
FLEXOO’s sensing technology can be integrated into complete monitoring solutions - from sensor layer to data processing
Designed for direct cell integration
Ultra-thin printed sensors integrate directly at cell level without requiring battery pack redesign.
