The Problem:
Ice buildup on exposed and rotating surfaces reduces performance and creates safety risks.
It increases drag and vibration, forces shutdowns, and leads to costly energy and maintenance losses in aircraft, drones, and wind turbines.
Where Current Ice Sensors Fall Short:
Most existing ice detection systems only respond after performance has already started to decline.
They struggle to detect early ice formation, often miss local icing on complex surfaces, and can trigger false alarms.
This leads to delayed response, unnecessary power use, and limited coverage on curved or rotating structures.
A New Approach to Ice Detection:
Repellion develops lightweight surface sensors that detect ice directly where it forms.
Using triboelectric sensing, the technology converts tiny surface interactions with ice and precipitation into electrical signals.
This allows systems to detect icing in real time and respond quickly while minimizing energy use.
Why Choose Repellion?
Early Ice and Rain Detection
Detects rain, snow, and early ice buildup at very small thicknesses (below 200 μm).
The sensor operates with extremely low power, making it well suited for energy-limited systems such as drones.
Automatic Response Control
When ice is detected, the system can trigger active or passive de-icing methods automatically.
This removes the need for manual intervention and helps reduce unnecessary energy use.
Ice Removal Confirmation
The sensor continuously monitors the surface and confirms when ice has been completely removed.
This allows de-icing systems to turn off at the right moment and avoid wasting power.
Designed for Multiple Platforms
Suitable for a wide range of systems, including aircraft, drones, wind turbines, and other exposed infrastructure
Thin and Flexible Integration
The sensor is extremely thin and flexible, allowing it to conform to curved and rotating surfaces with minimal added weight.
Compatible with Existing De-Icing Systems
The sensor can integrate with many ice-mitigation technologies, including thermal, electro-mechanical, pneumatic, and hybrid systems.
