Philip Morris International is test marketing a product employing new technology described by PMI as a mesh patch to heat e-liquids that eliminates manual assembly of wick-and-coil designs that are the industry standard.

PMI’s technology allows full automation in contrast to nearly all e-cigarette products that require wicks to be hand-threaded through heating coils, the company said in its latest Scientific Update for Smoke-free Products. A flat-coil product has been undergoing test marketing under the MESH brand in Birmingham, UK, since late last year, PMI said.
“The trick was to design a flat alternative to the original coil-and-wick technology that provided a comparable user experience to traditional e-cigarette products,” PMI said. “By designing a flat coil, a machine could place a flat wick on top of it, inject e-liquid into an adjacent cavity, and neatly seal it all in a self-contained cartridge.”
