I was wondering if there was any way to increase or decrease the sensitivity of touches. Also, Could the trackpad sense touches like sand or sugar?

The Morph can detect force from any material. Each sensing element detects forces approximately between 5g and 5kg. However, the Morph is not designed to work as a scale. Additionally any forces applied to the Morph slowly over time will be removed due to base lining. To turn off base lining, please use: http://guide.sensel.com/sensel_h/index.html#//apple_ref/c/func/senselSetDynamicBaselineEnabled
