a Design setup and target functionalities, i.e., high structural stiffness under mechanical load and large actuation performance under magneto-mechanical load; b Three optimized designs obtained by varying the weighting factors in Eq. 1. Notably, the design of Scenario 3 performs well in both target functionalities, i.e., structural stiffness and magnetic actuation.
