Electronic cigarettes: product characterisation and design considerations

Electronic cigarette (electronic cigarette) includes a wider range of product subcategories called Personal Vaporizer (PV), Advanced Personal Vaporizer (APV), or Electronic Nicotine Supply System (ENDS). These products have various designs. Complete characterization of electronic cigarette design functions is necessary to evaluate the potential risks and benefits associated with their use.

A systematic literature search was conducted in October 2013 to identify research related to electronic cigarette and electronic nicotine delivery systems. Using a set of related search terms, either alone or in combination, with 10 reference databases (Web of Knowledge, PubMed, SciFinder, Legacy Tobacco Documents Library, Embase, EBSCOhost, Espacenet, Google Scholar, Google Patent, and US Patent Office) I searched. Search conditions include "thermal runaway" or "battery fire" or "battery explosion" or "lithium battery explosion" or "electronic nicotine device" or "electronic nicotine supply system" or "electronic cigarette" or "electronic cigarette" . "Electron" and "Tobacco"

In order to be considered inclusive, the terms or patent (grant and application) are (1) written in English, (2) publicly available, (3) technical design or operation, or lithium battery Of fire or explosion shall be handled in part or exclusively. By search, a total of 296 electronic cigarettes articles or documents have been created that meet inclusion criteria. Next, narrow down the relevance between the title of the article and the abstract (details are insufficient in the title). In addition, thousands of batteries and patent documents were confirmed, about 100 copies of battery related documents and 460 patents were judged. Overall, in this search, 54 papers and 28 full-text review patents were created. This includes a manual search of the reference list to the selected article to identify other relevant publications.

After the full text review, 14 papers and documents and 16 patents documents were deemed to be directly related to the analysis. These articles and patent documents were issued between 2004 and 2013. The relevance and strength of each research was determined based on the depth and breadth of the analysis, the qualitative evaluation of the uniqueness and relevance of the engineering problem.

Other documents considered for review include conference reports / posters, reports not on peer reviewed journals, national and international standards, and government reports. Quote three documents from online sources or conference proceedings. Two Web sites that provide information on the design and operation of electronic cigarettes are also quoted. Although not peer reviewed, these sites and documents provide valuable insights on product design and operation.

Modern electronic cigarettes are attributed to Chinese pharmacist Hon Lik who invented the product in 2003. 1 Lik design acquired an international patent in 2007 (Electronic Atomization Cigarette: US 20070267031 A1). Electronic cigarettes were launched in Europe and the United States around 2006. 2 In recent years, worldwide usage is still very small, but the use of electronic cigarettes has increased significantly. Countries reporting the incidence of adults using electronic cigarettes include 0.3% in Indonesia, 1.2% in Italy, 1.9% in Greece, 5.9% in Poland 3. World electronic cigarette sales are estimated at $ 3.5 billion. Three major markets of the United States, Russia, Germany in 2015 (accounting for 60% of worldwide sales) 5 Electronic cigarette products are sold by manufacturers as substitutes for combustible cigarettes, and if cigarettes are not allowed It can be used.

A systematic literature search was conducted in October 2013 to identify research related to electronic cigarette and electronic nicotine delivery systems.
