  • Patent number: 11480560
    Abstract: A system comprising a respirator, a biochip, and an atomizer for studying respiratory pathogens. The respirator of the system is configured to create breathe-mimicking air movement, the biochip comprises an airway lumen in fluid communication with the respirator, and the atomizer is in fluid communication with the airway lumen of the biochip, according to various embodiments. The atomizer may be configured to generate droplets of a respiratory pathogen (e.g., from liquid inoculum). In various embodiments, the breath-mimicking air movement comprises air volume as a function of time, wherein the respirator is configured to generate breathing cycles.
