Basically, a vibrating mesh\u00a0nebulizer is composed of a liquid reservoir with a piezo\u00a0mesh disk mounted on one side of it, and a piezo mesh\u00a0driver circuit board with batteries. The piezo mesh disk\u00a0consists of a stainless steel plate that has been perforated\u00a0with thousands of precision-formed, laser-drilled\u00a0holes, and surrounded by a piezoelectric material.<br \/>\nThe piezoelectric material will vibrate at a very high rate\u00a0of speed when it is driven by an analog signal of specific\u00a0voltage, frequency, and waveform that is generated\u00a0by the driver board. As a result of rapid vibration,\u00a0solution is drawn through the holes to form droplets of\u00a0consistent size that are delivered at a low velocity to be\u00a0be inhaled directly into the lungs.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>A nebulizer is a medical device that is used to transform a liquid medicine into aerosol droplets so that patients with pulmonary diseases can easily inhale the medication into lungs.
