Electronic smoking article and improved heater element
An electronic cigarette includes a liquid supply including liquid material, a heater operable to heat the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol, and a wick in communication with the liquid material and in communication with the heater such that the wick delivers the liquid material to the heater. The heater is formed of a mesh material.
