On page 2964 Eduardo Mendes and co-workers report the production of large arrays of multi-responsive hydrogel cilia using microfabrication techniques. The cilia operate in aqueous solutions and are sensitive to pH, electric, and/or magnetic fields. Electrically stimulated cilia reversibly reduce their size by more than 80%. In the case of magnetoresposnive cilia, high-speed rotational movement is achieved. In addition, a biomimetic system that combines pHsensor triggered motility is presented.
