There has been a decent round of research publication recently. 

I find it interesting that there is some resurfacing of interest in using head-mounted haptics in order to help mitigate motion sickness, as demonstrated in these two recent studies (one by Oculus, no less).

Also good to see bend-sensing making a comeback as well.

I wonder if it'll ever make it into a product one day. It looks like it should in theory be pretty cheap, and if it could possibly just be integrated into clothing, that would amazing. Even with loose fitting clothing, it's possible we could use machine learning or a simpler statistical model to work out accurate limb locations. They claim no drift, and that the errors don't sum with each additional segment/length, which is amazing compared to IMU-only FBT. 

And an investigation of using haptics to induce a "penetrating" phantom touch sensation.
