Apparatuses and method are described to create a reduced stiffness microstructure (RSM). A RSM is made by forming a first buckled membrane along a first buckling direction and forming a second buckled membrane along a second buckling direction. The second buckling direction is opposite to the first buckling direction and the first buckled membrane is in contact with the second buckled membrane over a contact area. Within an operating zone, a stiffness of the reduced stiffness microstructure spring is less than an absolute value of a stiffness of either the first buckled membrane or the second buckled membrane when the contact area translates along either one of the buckling directions. In the operating zone the stiffness can approach or equal zero.
