Thanks Paula as thats a good idea. Maybe like the wrap that goes around arms when you give blood. It doesnt stick exactly but might hold the sensor in place so it doesnt fall off. It is most often covered by the sleeves on a shirt. Thanks,
just to clarify it is tan in color and stretchy and sticks to itself when stretched, not really like gauze which has no stretch so would get loose despite being secured by tape. If you search Coban that is made by 3M you will see what I mean. there may be others with similar properties, but the stretch and no adhesive are the keys. Again good luck
