====Ultrasonic wave nebulizer====
Ultrasonic wave nebulizers were invented in 1965<ref>{{cite patent|url = http://pdfpiw.uspto.gov/.piw?PageNum=0&docid=03243122|country = US|title = Ultrasonic Spray Apparatus|inventor = Snaper, Alvin A.|number = 3243122|status = patent|pubdate = 29 March 1966|fdate = 24 February 1965}} {{Webarchive|url=https://web.archive.org/web/20181029191628/http://pdfpiw.uspto.gov/.piw?PageNum=0&docid=03243122 |date=29 October 2018 }}</ref> as a new type of portable nebulizer. 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<ref name="Ultrasonic humidifier">{{cite web|url=http://www.airwin-luftbefeuchter.de/html/en/operating_principle.html|author=BOGA Gmbh|title=Operating principle of ultrasonic humidifier|access-date=2010-04-05|url-status=dead|archive-url=https://web.archive.org/web/20101114085152/http://www.airwin-luftbefeuchter.de/html/en/operating_principle.html|archive-date=2010-11-14}}</ref> via [[ultrasonic atomization]]. As they create aerosols from ultrasonic vibration instead of using a heavy air compressor, they only have a weight around {{convert|170|g}}. Another advantage is that the ultrasonic vibration is almost silent. Examples of these more modern type of nebulizers are: [[Omron]] NE-U17 and Beurer Nebulizer IH30.<ref>{{cite book |author1=Knoch, M. |author2=Finlay, W.H. |chapter=Ch. 71 Nebuliser Technologies |editor1=Rathbone |editor2=Hadgraft |editor3=Roberts |title=Modified-Release Drug Delivery Technology |publisher=Marcel Dekker |year=2002 |pages=849–856 }}</ref>
