Abstract

ESTE PEDIDO DE PATENTE DESCREVE A PRODUÇÃO DE UM DISPOSITIVO CONSTITUÍDO POR UM SISTEMA BIO MICROELETROMECÂNICO (BIOMEM) PARA PROMOVER A REGENERAÇÃO ÓSSEA ATRAVÉS DO REVESTIMENTO DE UM SUBSTRATO METÁLICO BIOMÉDICO COM UMA CAMADA DE ÓXIDO FERROELÉTRICO E PIEZOELÉTRICO FUNCIONALIZADO BIOCOMPATÍVEL OU COM UMA CAMADA POLIMÉRICA PIEZOELÉTRICA FUNCIONALIZADA BIOCOMPATÍVEL E BIODEGRADÁVEL. ESTA TECNOLOGIA RELACIONA-SE TAMBÉM COM UM MÉTODO EM QUE OS SUBSTRATOS METÁLICOS BIOMÉDICOS SÃO REVESTIDOS COM CAMADAS FERROELÉTRICAS E PIEZOELÉTRICAS BIOCOMPATÍVEIS DE LITAO3 (LTO) OU COM CAMADAS PIEZOELÉTRICAS BIOCOMPATÍVEIS E BIODEGRADÁVEIS DE ÁCIDO POLI-L-LÁCTICO (PLLA) FUNCIONALIZADAS ELETRICAMENTE POR CARREGAMENTO ELÉTRICO ATRAVÉS DE UMA CONFIGURAÇÃO DE ALTA VOLTAGEM SEM CONTACTO (POLARIZAÇÃO PELA TÉCNICA DE CORONA) OU ATIVADO POR RADIAÇÃO, UTILIZANDO RADIAÇÃO ULTRAVIOLETA (UV). OS SUBSTRATOS AÇO INOXIDÁVEL 316L (316L-STAINLESS STEEL 316L-SST) REVESTIDOS COM REVESTIMENTOS LTO FUNCIONALIZADOS APRESENTAM UMA MAIOR CAPACIDADE DE ENERGIA E DE HUMEDECIMENTO DA SUPERFÍCIE, UMA MAIOR TAXA DE FORMAÇÃO DE FOSFATO DE CÁLCIO E UMA MAIOR ADSORÇÃO DE PROTEÍNAS.
