“I was sure that the electronic cigarette would be welcomed with open arms”

Slightly old article here from back in July, but I’m seeing a lot of posts citing Herbert A. Gilbert as the inventor of electronic cigarettes. Whilst his 1963 device shares a lot with today’s e-cigarettes, it’s missing three important things: nicotine, flavour and vapour (Herbert’s device just involved inhaling moist, flavoured air).

The article doesn’t end well, and I certainly don’t hope we get the regulation Han Lik suggests, but it’s important to recognise him as the Chinese pharmacist who invented the modern electronic cigarette.

Sciences et Avenir : What pushed you to begin research on the electronic cigarette and what were the main challenges?

Hon Lik : My basic specialty is finding how to introduce our traditional pharmacopeia’s active substances into the human body. I used to be a big smoker myself and knowing the harmful effects associated with it very well, I told myself I couldn’t go on like that.

I tried nicotine patches but I didn’t care for the idea of slow diffusion of the drug into the organism. I missed the effect of the sudden impact, the act of smoking, the sensation of smoking. So I started thinking of a way to create vapor containing nicotine, similar to cigarette smoke but not as harmful for the organism.

In 2001 I devised a system on a large console, using food additives as solvents. At the time I was working on vaporization by ultrasound but the droplets formed were too big to resemble tobacco smoke. This technology is used for example in some household humidifiers; it consists of making a metallic diaphragm vibrate at an ultrasonic frequency in a liquid to create micro-droplets which then, upon contact with room-temperature air, form a sort of cold vapor.

I finally decided to use resistance heating which got better results. The challenge was managing to scale the mechanism down to a miniature size right for a cigarette and getting the right dose of nicotine, while also getting the right odors from harmless additives. This is how I came to file the first patent in 2003 in China.Sciences et Avenir
