Non-invasive glucose monitoring in the works at Apple?

On Thursday, August 23rd, Apple filed a patent for what looks like non-invasive glucose monitoring technology. Is the tech giant (finally) developing non-invasive glucose monitoring technology? Here’s what that might look like.

Tech blogs following the nitty-gritty details of patent applications pulled out details that hint at what Apple might be working on. The patent application for “Reference switch architectures for noncontact sensing of substances” describes a system designed to measure the concentration of a particular substance in a sample using certain wavelengths of light.



I found the following TED talk fascinating. It doesn’t specifically deal with glucose monitoring, but it shows how light can be used in amazing ways for non-invasive monitoring of many types. The speaker does mention measuring oxygen in the blood, so measuring glucose doesn’t seem impossible:
