Quiz: Galvanic Boosters, Anyone?

Handheld skincare devices may seem like a gimmick, but there’s quite a bit of engineering beneath their surfaces. Engineers combine current flow, vibration, and optics to create microcurrent and galvanic gadgets, which showcase the latest developments in bio-interface design. Beneath their small casings are circuit boards that regulate energy, sensors that detect skin contact, and housings that manage heat and motion. 

Do you know what these devices are doing beneath the skin’s surface? Find out with this ASME quiz.
