Thermo-Essence Technologies employee Matt Brazulea (L) passes a part to co-worker Will Phan as they assemble an electronic cigarette vaporizer at the company's office in San Carlos, California May 2, 2014. When Thermo-Essence Technologies co-founder Nathan Terry developed his e-cigarette he assumed the U.S. Food and Drug Administration would begin regulating the industry, as it has recently done, proposing a ban on sales to people under the age of 18 and requiring companies to register. Later it could impose product standard and quality controls. Terry wanted to create a product that would pass any FDA inspection. He used a pure metal wire wrapped around a rod made from magnesia-stabilized zirconia, a highly durable ceramic material. Instead of meshes, tape and plastic he used novel porous ceramics and surgical-grade alloys, and instead of soldering parts together he connected them mechanically, fitting components together like Legos to complete the circuits.
