Because those sensors are expensive, I made a sensor holder to keep it in place. The holder fits the sensor snugly and has extra holes to let the moisture out. For the adhesive, I use Kinesiotape or fysiotape.
The holder covers the adhesive layer from the sensor, so you can replace the Kinesiotape without damaging the adhesive layer.
The templates make it easy to cut the tape at the right size.
maybe it needs some sanding on the bottom, with extra fine sandpaper, I used Gritt 600. To make it smooth on the skin.
Some help to stick it on is recommended.
