Introduction
Toray Industries has developed a piezoelectric polymer with heat resistance exceeding 200°C, believed to be a world first. This innovation enhances vibration detection and monitoring across various industries.
Limitations of Existing Materials
Current piezoelectric materials like polyvinylidene fluoride and lead zirconate titanate have limitations. The former loses its polarization structure at 120°C, while the latter is hard and brittle, making it difficult to mount on complex shapes or large areas.
Applications and Demand
There is growing demand for vibration detection sensors in fields such as mobility, robotics, industrial machinery, and aerospace. These applications require sensors that can operate in high-temperature environments and cover large areas.
Innovation and Benefits
Toray's polymer maintains its polarization structure above 200°C, making it suitable for use in hot environments. It is available in varnish, film, or nonwoven fabric forms, allowing for versatile applications. Additionally, the material is free of lead and fluorine, complying with environmental regulations.
Future Prospects
Toray aims for practical applications of this polymer by 2028 and is currently providing samples to customers to explore and expand its uses.
