Like some of my other proposed designs, a key motivation is to circumvent the loss of nicotine from the traditional e-cig design (about half lost during vaporisation).

The present proposal is a twist, effectively, on the previously discussed 'hybrid' design. This time the idea is to separate the delivery of nicotine from the fog creating PG/VG and flavors in time.

In this scheme, the nicotine is delivered first, as a mist that could be generated in a number of ways, whether by ultrasonics, compressed gas or (electric) pump and nozzle (like an inhaler).

About one second later the device automatically switches over to producing a vapor of PG/VG/PEG plus flavorings; this could be generated in the same manner as with current e-cigs.

The timing would be controlled by a mini microprocessor in the battery (or between the atty and external power source). This type of microprocessor is already included in automatic batteries and could be added to manual designs too, very cheaply.
