Laser printing of micro-electronic communication systems for smart implants app...
Moura, Caroline Gomes; Carvalho, Óscar Samuel Novais; Magalhães, V. H.; Pereira, Rafael Santiago Floriani; Cerqueira, M. F.; Gonçalves, L. M. V.Endow the implant with intrinsic communication system between sensors and actuators or between implant and patient is a key factor for its long-term success. The capacity of early diagnosis of failures and the ability to remedy them are necessary to minimize expensive complications and reducing revision procedures. Ti6Al4V is the most used titanium alloy for implant’s fabrication. In this sense, this work prese...
Tuning electrical and thermoelectric properties of freestanding graphene oxide ...
Okhay, O.; Goncalves, G.; Dias, C.; Ventura, J.; Vieira, Eliana Maria Fernandes; Gonçalves, L. M. V.; Tkach, A.Electrical conductivity and Seebeck coefficient of freestanding paper of graphene oxide (GO) and GO reduced by heat treatment at 180 degrees C (rGO) are tuned by addition of carbon nanotubes (CNT). The electrical conductivity of rGO with 50% of CNT is raised to similar to 2940 S/m from similar to 613 S/m for pure rGO or similar to 34 S/m for GO with 50% of CNT without reduction. Moreover, Seebeck coefficient of...
Laser surface texturing of Ti-6Al-4V by nanosecond laser: Surface characterizat...
Moura, C. G.; Carvalho, O.; Gonçalves, L. M. V.; Cerqueira, M. F.; Nascimento, R.; Silva, F.The development of smart biomedical implants with intrinsic communication system between sensors and actuators, or between implant and patient, remains a challenge for scientific community. Titanium and its alloys, especially Ti6Al4V, are the most used materials in the implant's fabrication. The present work is concerned with implant internal communication printing process and presents a detailed study on titan...
