Technical Description
The invention is a low-cost, ultra-highly sensitive vapor sensor device and fabrication method that coats a conductive polymer thin film onto a flexible, non-conductive substrate. Strain-induced micro-cracks are plasma-etched to lock in high resistance, which vapor exposure to bridges via polymer swelling to spike electrical conductivity.
Problems Addressed
- Poor baseline reproducibility
- Slow response and recovery cycles
- High manufacturing and material costs
- Limited sensitivity and subdued electrical
- Unreliable or unprecise sensing behaviors
- Complex structural layers and surface reaction
Tech Features
