ONLINE COVER Powerful and Precise. Conventional motor technologies are heavy, lack flexibility, and do not retain efficiency or power density at small scales. Kedzierski and Holihan developed linear and rotational microhydraulic actuators that have high power density and efficiency and that improved when scaled to smaller dimensions. Such lightweight, flexible, and accurate actuators may find many applications in soft robotics and biomedicine. [CREDIT: GLEN COOPER/MIT LINCOLN LABORATORY]
