Advanced Material Development said it is holding talks with potential partners in the RFID antenna industry as progress continues to be made in developing the company’s proprietary Conductively Optimized Graphite (COG) nano-material.

A research paper just published in the prestigious Advanced Material Technology scientific journal has described some of the research by the teams at the universities of Sussex and Surrey that are working on COG with the company.

In the research, the teams assessed the performance of the COG antenna in a practical system using an RFID reader, whereby the transmitter power is progressively increased until the tag is successfully read.

In the paper, the teams described how this early-stage prototype successfully achieved read distances of more than 2m in lab conditions, with theoretical ranges beyond 11m. 

“Ongoing work in the Sussex labs continues to improve the print qualities of the conductive ink for commercial production needs,” AMD said, noting that the Sussex team has returned to lab work after the coronavirus shutdown.

AMD, which owns 100% of all critical and underlying IP, said talks with a number of potential global partners about further developing and deploying this ‘green RFID’ solution.

Graphene’s low cost of production, high performance and environmental sustainability make it a potentially important material for use in electronic devices. 

Sussex and Surrey are two of the three universities with which AMD works to fund and commercialise university-based nanomaterials research.
