Glucology Sensor Shields are soft, stretchy overpatches that sit over your Dexcom G7, ONE+ or Stelo sensor and add an extra layer of hold for the full wear period. A non-stick center sits over the sensor itself, so patch changes are easy, and a vent hole lets it breathe. The wavy-edge adhesive moves with your body.
✅ Extra hold – helps prevent lifting and peeling edges
✅ Water- and sweat-resistant – for showers, swims and workouts
✅ Breathable cotton-spandex blend – stretches and moves with you
✅ Gentle on skin – latex-free adhesive
✅ 25 patches per pack – available in 4 colors
✅ FDA Listed
✅ Australian-owned since 2016 – trusted by 350,000+ customers worldwide
Compatible with: Dexcom G7, Dexcom ONE+ and Stelo
Please note: Don't apply over irritated, cut, scraped or broken skin. Sensor Shields add to your sensor's own adhesive rather than replacing it – always follow your CGM manufacturer's instructions.
Q: How long does one patch last?
A: Each shield is designed to last a full sensor wear period. Wear time varies with skin type, activity and climate.
Q: Can I swim and shower with it?
A: Yes. Sensor Shields are water- and sweat-resistant. Press the edges down again after swimming for the best hold.
Q: Using a different CGM?
A: We make Sensor Shields for Dexcom, FreeStyle Libre, Omnipod and Medtronic. Browse all Sensor Shields.

Unfortunately despite applying it as directed it started to peel off within a week.
Essentially does what it’s supposed to do, but getting the back of the adhesive off is a nightmare as the perforated lines are cut terribly
These are really amazing and have stuck on tight on sweaty Qlder skin, where majority don’t.
Buyers fault, I thought I clicked on Omnipod, but it defauled back to Dexcom, so now I cut out the pod’s shape and no problems sticking the same…… I can match both devices if I like 😊
Thanks for taking the time to share your feedback with us JK. It means so much when our customers share their experiences.
I’m glad we were able to meet your expectations!
I really love this product as it sticks but that is if you do it properly. Wiping down with an alcohol swab and applying it over the CGM. I really love the design and as long as you don't shower too often or have water on it a lot, it will last!

I’ve been a bit disappointed with the patches. After 2 days of wear they have lifted on the edges and end up getting caught on clothing and lifting further. I’ve tried on 2 different sites (belly and arm) but had the same issue for both.
I love my CGM Patches. I’ve always had trouble with my CGM adhering for the full duration of 7 days. Once I found these patches and paired them with Skin Prep & Skin Tac Wipe, I no longer have issues.
Thanks for the review Judith!
I’m glad we were able to meet your expectations!

Surf..not durable!
Special purchase for surf..followed every direction. New to T1D so very concise of taking care. Product Fail. Asked on FB groups for help..transmitter even had water between it and the Sensor.
May I suggest you market a whole arm band..a product to wrap around the arm.
Went to surf today..wore a Physio Strap..dexcom didn't move. I'm sure you'll get there but, I think I wasted my money.
Item is not waterproof and comes off within a day or two. I’m on my 3rd in 4 days. At least when they do fall off and they do, the sensor tape is still stuck to my skin. Item easily lifts up on the edges. Thank goodness they put several in a package and they are cheap.
My daughter is an athlete and unfortunately the patches came loose during training due to sweat. Position was cleaned with skin wipes prior to positioning the patch and firmly pressed to the skin for required amount of time and also rubbed to secure. On the daily they are great just a small problem with sweat when doing high intensity training.
These new slightly elongated patches give me more coverage on my sensor.
They stay on and can be worn in water.
Hi Judith, we're so glad to hear that you're happy with the patches! Thanks for sharing your experience.
They work great. Stick to my skin for 2 weeks just fine. Sometimes it starts to pull up on a small section. I just cut those off as close as possible and push down on the rest, and it doesn't come up anymore.
Hi Jerry, we're glad to hear the shields are working well for you! Thanks for sharing your tips on application. If you ever need assistance, we're here to help!
No matter what I do, I can not make it stick. Everyone that I have tried. In some section of the pad doesn't stick. So I'm not using it any more. I gave up.
The patches are great, they do exactly what they are supposed to do, I bought the patches because I am a rough sleeper but the patch has kept my sensor in place for Two weeks straight. No problems with sweat or showering, they dont budge, great product

Beautiful pattern and lovely cotton material , super easy to place over GCM . Only issue that it started to lift on the eighth day and was gone by the tenth . I will check full instructions again as it really lovely and I’ll try again 👍
This patch is easy to apply. My sensor is more securely fixed to my arm with this patch and it remains quite dry after showering. Importantly it is easy to remove.
