Controllable adhesion to glass spheres with a new magnetically actuated synthetic gecko adhesive made from a magnetoelastomer is demonstrated. Adhesion is controlled by orienting the microfabricated surface features with an external magnetic field. Results show sphere pull-off forces can be increased 10-fold by changing the ridge orientation. Applications include solar panel cleaning, reusable adhesives, and microfabrication.
