Applications
Sensor that is real-time and continuous, for humidity, organic vapors, pressure, mechanical force, light, temperature or specific chemical species.
Target Problems
Manufacturing methods to generate structural color (i.e. physical structures) are generally tedious and costly, resulting in limited commercial use. In addition, available films are rigid, lack organic based materials, and may be subject to environmental degradation. The commercial electronic-based humidity sensors are expensive and require power. The commercial paper-based humidity sensors use cobalt chloride, which are cheap and do not require power, but have several major issues: toxicity (cobalt chloride is toxic); non-real-time sensing; limited reliability and shelf life.
Key Benefits
- Lower cost
- Zero power consumption
- Flexible material
- Good processability
- Excellent corrosion resistance
- Light-weight
- Fast, dynamic and reversible response
- Spatial and temporal resolution
Technology
This invention uses a layering technique which exhibits structural color, specifically, the light response of a structure involving a versatile polymer layer backed by a thin versatile metal layer on a substrate.
