Abstract Multi-stable structures attract great interest because they possess special energy landscapes with domains of attraction around the stable states. Consequently. multi-stable structures have the potential to achieve prescribed reconfiguration with only a few lightweight actuators (such as shape-memory alloy springs). and do not need constant actuation to be locked at a stable ... https://www.lecoureures.shop/product-category/ski-de-fond-equipement-fixations-classic/
