I do, I buy the rolls of hypafix of 10 cm x 10 m and cut squares.
I usually cut a bit of tissue (no, toilet paper really, it's cheap) the size of the sensor so the patch doesn't stick to the sensor itself in case it needs to be replaced before the two weeks are over. But mostly the patch holds on for the two full weeks.
I've done it like this for the past 8 years.
