Extreme‐Temperature Resistant, Flexible, and Sensitive Strain Sensor for Aerospace Parachute Deployment

Advanced Materials Technologies, EarlyView.
In this study, we report a resistive‐type strain sensor fabricated using single‐walled CNTs, are used layer using the pray technique to deposit as conductive, and UV‐resin was spin‐coated as a protection layer. The sensor functioned in harsh temperature variation conditions from −50°C to 125°C without deterioration.
