Abstract

SENSOR DE LIMITE DE PRESSÃO BASEADO EM CAPILAR PARA LÍQUIDOS E MÉTODOS E APARELHOS USANDO O MESMO. Sensores de limite de pressão baseados em capilar são fornecidos para líquidos que exploram as propriedades de membranas porosas hidrofóbicas, super-hidrofóbicas, oleofóbicas e anfifóbicas para detectar quando o fluido passa através da membrana no caso de a pressão através da membrana aumentar acima da pressão de penetração de um fluido. Implementações de exemplo são fornecidas de diferentes configurações para um sensor de limite de pressão baseado em capilar e de como um sensor de limite de pressão baseado em capilar é usado em um dispositivo de entrega de medicação ou outros dispositivos de entrega de fluido para detectar a oclusão ou outra condição de fluxo de fluido.
