Abstract
The labyrinth of foil inside a glucometer strip reveals a fragile chemistry. If you peel open the plastic covering, many inner circuits contain some version of biosensor technology, electrochemical cells screen-printed with gold or other precious metals and coated in places with enzymes. The foil serves as a conductor for electrons in a drop of blood, allowing a brand-matched glucometer machine to measure the charge a sample holds. Yet costly design components (including gold) are also part of the reason that glucometer strips remain too expensive for most people in the world who have diabetes.
