Abstract

uma cabeça de ejeção de líquido (1) inclui um orifício de ejeção (12) através do qual um líquido é ejetado, um primeiro percurso de fluxo de líquido (13) que está em comunicação com o orifício de ejeção (12) e através do qual o líquido flui, um segundo percurso de fluxo de líquido (14) que está em comunicação com o orifício de ejeção (12) no lado oposto do primeiro fluxo de líquido (13) com relação ao orifício de ejeção (12) e através do qual o líquido flui, um primeiro eletrodo (21) posicionado no primeiro percurso de fluxo de líquido (13) e um segundo eletrodo (22) que está posicionado no segundo percurso de fluxo de líquido (14) e gera um fluxo eletro-osmótico no líquido juntamente com o primeiro eletrodo (21).
