Flexible, stretchable sensors

Abstract/Technology Overview

A sensor which is flexible or stretchable for use in many applications including detecting a hazardous substance and/or electromagnetic radiation.  The invention has particular use in detecting the presence of hazardous gases and liquids as well as detecting ultra-violet (UV) radiation. Such transparent and flexible or stretchable sensors offer significant potential for the development of cost-effective, bio-compatible, functional and curvilinear electronic and optoelectronic devices.

This technology demonstrates that the incorporation of electronic materials, in particular, functional metal oxides onto mechanical conformal platforms offers a new pathway for the development of sophisticated, stretchable electronic devices that can be bent, stretched, twisted and folded into complex curvilinear shapes while maintaining their electronic characteristics, performance and reliability.

The technology has application for novel systems such as in vitro pH sensors, transient and printable electronic devices, sensory robotic skin and wearable electronic devices

Technology Features, Specifications and Advantages

·       The flexible and stretchable sensors for use in detecting a substance and/or electromagnetic radiation.

·       Sensors can be incorporated on non-planar geometries, which is a challenge with existing technology.

·       Patent protection has been sought for this novel flexible or stretchable sensor and the method for the detection of substances and/or electromagnetic radiation, such as detection of hazardous substances and radiation.
