Desenvolvimento de um sistema de eletrodeposição de filmes finos de ZnO para EGFET como sensor de pH
     Development of an electrodeposition system of ZnO thin films to EGFET as pH sensor

Edgar Monteiro da Silva, Pablo Diniz Batista

Resumo


A partir de 2004 aumentou o interesse da pesquisa científica em sensores de pH baseados em filme fino de óxido de zinco utilizando transistores de efeito de campo. A produção e caracterização destes sensores normalmente são feitas a partir de equipamentos comerciais, que nem sempre estão disponíveis para todos os pesquisadores. Dentro dessa perspectiva e com o objetivo de colaborar com a pesquisa nesta área, este trabalho propõe a construção de um sistema de eletrodeposição com baixo custo para facilitar a produção, a caracterização e a investigação do filme de ZnO como sensor de pH. Este projeto está baseado no paradigma {\it open source hardware}.


Palavras-chave


sensor de pH, ZnO, EGFET, eletrodeposição, potenciostato.
