I got quite a few questions on what get I used to encapsulate the IMU. The gel is the Dow Corning Sylgard 527, the consistency of the gel is controlled by the proportion of part A vs. part B. I used 70% part B and 30% part A. After you mix the two parts you need to heat the mix (and the board in it) in order to cure. I put it in an oven at about 70 degC for 2 hours. It will also cure at room temperature but it may take several days.
