Abstract

Sistemas de detector de respiración de gas confiable, rápido y barato para diagnósticos médicos, incluyendo dispositivos de monitoreo portátiles, personales, para una variedad de enfermedades y padecimientos, incluyendo por ejemplo, asma, diabetes, colesterol en la sangre y cáncer de pulmón. Un dispositivo (100) sensor para detectar gases incluye un elemento (109) de detección que tiene una resistencia eléctrica que cambia en la presencia de un gas objetivo, un circuito de lectura, acoplado eléctricamente al elemento de detección debido a la presencia del gas objetivo y convierte la medición a una señal digital; y un bucle (203) de retroalimentación desde una unidad (205) digital al circuito de lectura para compensar las variaciones en una resistencia de línea base del elemento de detección.
