Subsequent mechanical stresses in the branches determine where new branches will begin to develop and, in turn, produce their own signaling molecules.

To minimize the current due to this effect, it's important to remove mechanical stresses from the insulator and use insulating materials with minimal piezoelectric and stored charge effects.

Before weaving, the warp threads are coated with a size (a dressing) to enable them to withstand the mechanical stresses involved in the weaving process.
