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.
