Optical pressure sensor based on zirconia nanostructures

Posted by UATEC - Unidade de Transferência de TecnologiaResponsive · Patents for licensing · Portugal

Summary of the technology

A group of researchers from a Portuguese university has developed the concept of a gas pressure gauge based on the control of the luminescence from zirconia nanostructures. The invention aims to measure the gas pressure based on the nanoparticles emission that is different depending on the amount of gas molecules surrounding the nanoparticles. Comparing with existing solutions, the advantage of this process, which operate in a pressure range of interest for various market sectors (ex. Food industry), is the absence of electrical contacts. The university is looking for companies that develop this type of solution on an industrial scale for the further joint development of specific applications or technology licensing.

New and innovative aspects

The present invention has the following advantages over existing technologies: a) no electrical contacts, being the pressure inferred optically, b) use of biocompatible material, c) flexible handling system.

 

Specifications

A Portuguese university developed a solution to overcome the commercial inexistence of wireless pressure sensors. The degree of product innovation lies in using a contactless technology based on the colour emission of zirconia nanoparticles due to the pressure of the surrounding environment. Sensors based on this technology benefit from not require electrical contacts being the pressure registered with the naked eye taking into account the colors emitted by the nanoparticles. These characteristics allow the applications in packaging and related food industry. Furthermore, it is important to mention that the nanoparticles are biocompatible.

The university aims to license this technology to companies with development or production and marketing capacity of sensors for the development of business solutions based on the technology. The university is also available to participate in this development through a joint venture project or its subcontracting.

 

Applications

  • Application as pressure sensors for food, aerospace and vacuum technology industries.

 

Intellectual property status

Pending patente application.

 

Current development status

Tested in the laboratory as proof of concept.

Desired business relationship

The university aims to license this technology to companies with development or production and marketing capacity of sensors for the development of business solutions based on the technology. The university is also available to participate in this development through a joint venture project or its subcontracting.
