We have some 4" wide stretch medical tape which works very well to hold the device firmly in place. The tape holds well but is easy to remove. It is very stretchy so follows the contour of the muscle well and gives nicely with movement. Pictures attached.

Reading through some of the problems people had with the placement and fixation you can see, that Herb gave a great solution.
Many of the often seen artifacts are produced by the way you mount and fix the device. If you use a sleeve or all around tape than you already create a pressure, which during exercises will be enhanced depending on the motion you do and the activation of capillariation in and around the place, where you placed the device. So in cycling for example, where you create a huge ROM with your knee and with it a big change in diameter on your quadriceps you will always see a big interfering but as well a change in actually readings. The below picture shows you a tHb view during a cycle test over 10 seconds with closer view of a NIRS and you can even see , what the RPM of this athletes where. This are 2 world class athletes one test is done in Switzerland on a Japanese top athlete and the other here in Quesnel BC Canada on one of the most successful MTB guys in northamerica. You can see the smooth pattern due to the way we apply the equipment. It as well shows you , whether we have a symmetrically oxygenation, when we apply the equipment on both sides. We can apply 4 and more sensors now and even can run both simultaneous on the screen to see quality of movements and at the same time we run a live quality signal control to be sure we have never a influence of motion and or light. When applying any kind of NIRS you always cover the equipment with a black cloth below the stretch tape as well you apply the MOXY so you have R and T from caudal to cranial or visa versa and not in a horizontal plane, as the ITB will interfere with the light source So this picture is only to show you the idea of the tape but the placing and the optode position is not the way we suggest.
