Episode The Chip That Measures Your Glucose Every Five Minutes
In this episode, we dive into the chip inside Dexcom's G7 continuous glucose monitor — a coin-sized electrochemical sensor that measures glucose every five minutes for ten days. We explore how the chip miniaturizes a lab-grade chemistry setup using glucose oxidase enzymes, amperometric detection, and on-chip signal processing. Lucas explains the challenges of stability, calibration, and the body's immune response, while Luna discusses the competitive landscape with Abbott's FreeStyle Libre. We also touch on future directions like multi-biomarker sensing and closed-loop insulin delivery. A behind-the-scenes moment reveals how listener support keeps the podcast ad-free and focused on deep tech details.
