I'm very happy to share my latest publication with Prof. Danilo Mandic, "An In-Ear PPG-Based Blood Glucose Monitor: A Proof-of-Concept Study"!

This research explores, for the first time, the ear canal as a potential site for non-invasive blood glucose monitoring. The in-ear sensor uses photoplethysmography (PPG) in combination with machine learning to estimate blood glucose levels without the need for painful fingersticks or invasive devices.

My aim is to make diabetes management easier, more convenient, and less expensive for millions of people around the world, paving the way for earlier diagnosis and enhanced treatment of diabetes.

I'd love to hear your thoughts and opinions on this new approach to blood glucose monitoring. Let's discuss!

Very cool! I'm currently wearing a CGM. I already love these and find them super non-invasive (Freestyle Libre 3). It's a penny that sits on your arm and every 14 days you change it for 1 minute.

But this would probably be even cooler.

Do you think there would be other locations that lend themselves to this, besides ear canal? People already use their ears for headphones a lot, so it might be difficult to use for some.

Thank you for your comment! The main idea is to integrate this sensor with earbuds or hearing aids, since these are already widely used.

Oh, I see. Hope you succeed. If this technology makes its way into the Apple watch or AirPod we'll reduce T2D by 100 million over night.

Cool stuff! Any physiological reason why the ear canal would be better suited for PPG compared to a say something like a PPG device in a watch?

Thanks for your comment! The ear provides an excellent alternative to the wrist when it comes to temperature stability, constant pressure between sensor and skin and the relatively cleaner signal given that in general the head moves less than our wrists.
