The technology inside an ultrasonic wave nebulizer is to have an electronic oscillator generate a high frequency ultrasonic wave, which causes the mechanical vibration of a piezoelectric element. This vibrating element is in contact with a liquid reservoir and its high frequency vibration is sufficient to produce a vapor mist [ 17 ] via ...
Thus the company was approached to develop an alternative. The result was the Both Respirator: a lightweight, comparatively inexpensive respirator made out of plywood (the name "iron lung" continued to be used by many, in spite of the wooden construction). The design proved effective, and the respirators were soon employed throughout Australia.

While the 4 other competing type of inhalers are relatively new inventions. The first "gas inhaler" (or breathing apparatus) was invented and designed by James Watt in 1793. The first nebulizer was invented and designed by Sales-Girons in 1858. The first dry powder inhaler was invented by Newton in 1864.

Claude Shannon (1916–2016), founder of information theory and modern cryptography, invented Minivac 601, and co-invented the first wearable computer (with Edward O. Thorp) Ugo Cerletti (1877–1963), together with Lucio Bini (1908–1964), Italy – Electroconvulsive therapy; Leona Chalmers (c. 1937), U.S. – modern menstrual cup
At the tip of the nebulizer, the liquid is pulled into the gas stream by surface tension along a spout dipping into the gas stream. This allows the gas to impact the liquid, and has the liquid interact in the center of the gas flow where the gas flow speed is highest, producing a better transfer of energy from the gas to the liquid, and ...
