The End Work Master Eva Maria Ortiz optimized antennas RFID tags, doubling its reach with dimensions one third lower
Telematics and master engineer in Telecommunications Eva Maria Ortiz has achieved its final graduate project significantly improve the performance of integrated labels in blood bags antennas, enabling identification much faster and reliable.
The End of Work Master student at the Polytechnic University of Cartagena (UPCT) helps to improve traceability and transfusion safety and streamlines the management of stored blood.
It also prevents the insulating placement next to the antenna, as used in smart dorsal sporting events.
The investigation, which has led Professor Alejandro Alvarez Melcón, optimized performance of RFID tags (Radio Frequency Identification) antenna with different sizes.
"We have tripled the size range with currently used and antennas proportions doubled with a small third, reducing cost," summarizes the teacher.
"The antennas receive the radio frequency signal reader and activate a chip that emits the identification information about the blood," says the student.
"The problem is that the blood can absorb radiation and detuning the antenna, so far the only effective reader was standing at between 30 and 40 centimeters.
With our antenna can be detected identifiers to meter and a half, enabling the reading of many more bags at once, "he argues.
"We start from the existing antennas on the market and those proposed by the scientific community and we went optimizing introducing and bending dipoles between two metal plates," explains Ortiz.
"It was an achievement that measurements made in the anechoic chamber UPCT coincide exactly with simulations that Eve had done" says the director.
The student, 24 and Molina de Segura, is now co-directing a Final Degree Work to improve identification antennas blood tubes.
The student also highlighted as a fellow of the Telefonica-UPCT Chair to be selected its project of a new business architecture for using Android from virtual devices in the cloud as a national finalist technological entrepreneurship program Talentum Startups.
